How do I grow 303 OG marijuana seeds?

303 OG marijuana can be successfully grown both indoors and outdoors, with each method offering distinct advantages. Indoor cultivation provides better control over environmental factors such as temperature, humidity, and lighting, resulting in optimal plant growth. It thrives in a controlled indoor environment, making it suitable for growers with limited space. On the other hand, outdoor cultivation allows plants to benefit from natural sunlight and fresh air, potentially leading to larger yields.

What do 303 OG marijuana plants look like?

303 OG marijuana plants exhibit distinctive physical characteristics that make them easily recognizable. They typically have dense and compact buds covered in a thick layer of trichomes, giving them a frosty appearance. The leaves are deep green, and broad, and often exhibit shades of purple, especially during the flowering stage. The plants tend to grow to an average plant height, with sturdy branches that can support the weight of the resinous buds. Overall, their aesthetic appeal is enhanced by the abundance of resin and the vibrant colors they display.

When to harvest your 303 OG marijuana seeds

The ideal time to harvest 303 OG marijuana depends on several factors, including the desired effects and the strain’s flowering period. Generally, it is recommended to harvest when the trichomes on the buds turn milky white or amber, indicating peak potency. Indoor plants typically have a flowering period of 8-10 weeks, yielding around 400-500 grams per square meter. Outdoor harvest usually occurs in late September to early October, resulting in a yield of approximately 500-600 grams per plant.

    You can relieve all your stress and feel free, oh so free, with 303. This is an indica-dominant hybrid that will give you this nice relaxing high that you will feel take over your entire body. The smoke is creamy and smooth and will have you ready to lay it down for the day.

    303 OG has an excellent stress-relieving property to it, the smooth hit and strong high allow me to enjoy a day without any worries at all. I did not get a large amount of weed compared to other seeds I’ve grown but these seeds still have a moderate amount.

  4. David Murray (verified owner)

    Stress? What stress? 303 OG is a great strain to kill off any stresses life has to throw at you. This high THC strain will force it all out and flow through your body to let you relax and enjoy the rest of your day.

  5. Amanda Wright (verified owner)

    Had some mailing issues at first, explained the situation and customer support hooked me up no problem! Great customer service only added a great experience once i got the seeds, have yet to finish growing them but so far so good, been about 4 weeks in and the progress is promising.

  6. Abdullah Humphrey (verified owner)

    303 OG is the perfect after-work strain. It’s an easy grow, too, which is why I was so excited about it. It takes about 3 months, a definite summer hobby for me 🙂 I got recommended this site by a friend. We always smoke pot together and recently she started sharing her homegrown stash and I was floored by the quality. I knew I needed to buy my own seeds and start growing at home. GREAT product. Very excited to return the favor!

  7. Charlize R (verified owner)

    I have been around weed most of my life since my parents were marijuana farmers (among other things). I took up the business in my 30s but recently decided to just grow pot for myself. Great shipping rates on this site with a superior product. Highly recommend you try it out, it’ll change the way you smoke weed!

  8. Huseyin M. (verified owner)

    Been a west coast grower since before the “green rush.” Happy I had the knowledge and skills before all these new kids try their hand at the cannabis game. I used to grow commercially, and my product is still in demand after a few seasons of business, but now I am getting too old to stay up to date on all the rules and regs so I grow at home, for my lone self 🙂 I still love the practice and have gotten quite good at it. 303 is a win for its strong indica profile and forest-floor flavor, MMMmmm earthy!

  9. Mirza Turner (verified owner)

    Great weed from the great state of Oregon. Perfect for coastal growers….highly recommend growing in a greenhouse or indoors for best results….. a sturdy plant with a medium yield. Usually produces between 500-800 G among 3-5 plants. You’ll be amazed at the tight, well-formed flowers and bright, citrusy smell!

  10. Alessandro Ridley (verified owner)

    Goooood weed! Fast shipping and delicous flavor. I bring my all to growing MJ. It’s such a fun process!! I bought 10 seeds and they shipped right quick. It’s absolutely gorgeous and brilliantly colored. I love the way this works and hope it can happen again, maybe I can grow indoors next time?? Good buy!!

  11. Katey Spence (verified owner)

    The 303 OG is the strain for me. The smooth citrus flavor makes for an amazing uplifting experience that hits me in all the right ways. It’s a super green color and very fresh!

  12. Montgomery O’Sullivan (verified owner)

    This weed might just change yr life. It’s got fat nugs and some very high profile textures that make it one-of-a-kind! Gets me baked like a true hero. I am stoned AF on my couch right now!

  13. Edgar Young (verified owner)

    Best damned weed on the internet! After DAYS of looking for the perfect weed, I finally found what I was looking for. It’s so nice to have this stuff available. Easy to grow, nice to maintain. Definitely a unique style of mj that makes me smile!

  14. Oakley O’Brien (verified owner)

    303 OG is a prize-winning strain in my book. This light, green feathery weed is perfect for smoking in the mornings or afternoons for a little bit of an uplifting high that clears my head and makes me feel much more zen and focused. Not a professional grower, but I do have good luck with these seeds, they always germinate and produce at least a couple hundred Gs.

  15. Amit Hogg (verified owner)

    Great smelling strain and even better looking. Gets me nice a high and opens up new doorways in the mind. Brings me closer to joy every time I smoke it. Ordered online and had it shipped to my place. Only took a few days! I like the earthy smell, the sweet flavor and the mellow buzz that will make any west coaster breathe easy.

  16. Nakita Williams (verified owner)

    Oregon man, what a crazy chilled out wacky state, the PERFECT place to grow marijuana, and a SWEET hobby to impress the ladies with. I smoked constantly the other day, joint after joint and I gotta say this is some SWEET weed that gets me high as a kite and feels great in my body!!

  17. Tylor Webber (verified owner)

    303 Og is where I am from man, that’s like my teenage years on the west coast, and it’s feeling pretty good man. I am so very happy and stoked about my new weed supply. They look amazing in the backyard, and all my friends are just crazy about them. I smoke this dope and then go rock climbing and boarding!!

  18. Brent Downs (verified owner)

    Never tried out the 303 strain before but it’s been really great for my depression. Have had nothing but good luck with this strain and always enjoy the sweet and sour vibes that come with this beautiful flower. I feel marijuana is magic, and I think this is something I want to invest in doing for a long time!!

  19. Fahima Hussain (verified owner)

    303 OG is a good old time, it’s a great middle-of-the-road-kind of strain and it helps me relax. I am just a very stressed-out dad and helping my daughter grow up is a hard time, so I smoke a little bit of this after she falls asleep and it makes my life a lot easier. She doesn’t know or seem to mind and I enjoy working in the garden.

  20. Ferne Watkins (verified owner)

    303 OG is the weed of the Oregon trail….that;s right, THAT Oregon. Okay, so bought my seeds online and like woahhh they shipped hella fast to my doorstep and here we are, 5 months later, the precipice of greatness, about to smoke ma own dank herbbbbb!!! Yess, getting stoned is the best! Gotta stay high.

  21. Trey Floyd (verified owner)

    Time to get nice and cozy and load up a FAT bowl of the 303 OG…this weed is a true gem…it’s a great way to stay busy during quarantine…which seemingly will never end…I am very excited though for the next harvest which is coming up…these nugs are absolutley magic…they are bright green and blue and are suuuuper sitcky too!

  22. Della Holden (verified owner)

    Are you ready to have your mind blown? This indica laden strain is hella fun to grow. It makes my life soooo much better, and it gets me seriously high!!! It’s the kind of strain you wanna smoke out of a HUGE bong and then order thai food and just veg out! Have been very happy with my grow and will buy from here again!!!

  23. cryptopyro (verified owner)

    The 303 OG is a really awesome strain. It helps me deal with all the pain and stress associated with my daily life struggles and it makes me kinda just chill and happy and I want to just eat a lot of pad thai and play mario Kart till 4 am. I am very pleased with the result and definitely wanna keep trying you know?

  24. alpacapaca (verified owner)

    I am a west coaster so this area code means something to me! I ordered online, got my seeds delivered to Oregon, and started growing right away…not a bad choice if you’re looking for an easy grow with a big yield, plus it’s an OG strain, so you can experience some nice vibes and good times in the evening!

  25. Bruce Hotchkis (verified owner)

    WOW, that’s all I can say about this weed….it’s neon green colors and super fluffy texture makes this a real winner in my mind. I am very excited to harvest….it’s been about 4 months of working in the garden….but it’s all about to Pay Off! I can’t wait to start smoking this marijuana to help me with my anxiety….it’s got all the chill vibes of the west coast!

  26. Robert Ojeda (verified owner)

    303 OG is my home area code and I am super stoked to find some Colorado weed on this website…I am amazed at just how easy this was to grow, and I am by no means an expert grower…got myself 3 seeds and followed the very helpful grow guide on this website. I found that if I gave my plants an even amount of water and pruned often, they were very happy. Can’t wait to buy more!

  27. Rightnow (verified owner)

    Gotta love these Colorado strains….they are some of my favorite cause they have been bred to grow in a more arid climate, which is great. Got myself 3 seeds online and had them delivered right to my place. I finally got my new grow room set up and these little guys did really great in there. Once it was time I moved them outside and they got HUGE and made some great weed. So fresh!

  28. RUMPROAST (verified owner)

    I don’t know what kind of sorcery went into developing this strain, but the end product is incredible! I grew this plant in a legal state in New England last year, my first year growing. Ran two plants in the same size fabric pot with the same planting medium: topped one, and let the other one pretty much do her thing. Yielded 270 and 200 grams, respectively, even with a bunch of mistakes during the early part of the grow. Plants were quite mold and pest-resistant, compared to the ECSD plants grown in the same garden, pots, medium, etc.

    How’s the smoke, you ask? The high? Incredible on both counts. Smooth and tasty smoke (properly dried and cured to the best of my knowledge), and a very mellow, kind of creeping high. I smoke this after dinner, another toke before bed, and end up with a smooth, comfy and warm cruise into bed. My wife especially loves this strain: she doesn’t smoke, but tells me I’m much easier to deal with after a hard day when smoking the 303OG.

    This review comes after popping TWO 2019’s growing (and smoking) season, and I just ordered 10 for this year!

  29. Tacotruck Chaser (verified owner)

    If you need a rush of euphoria, but don’t have much time in your afternoon, just take a few tokes of this delicious herb and you will fee right as rain. I definitely recommend buying 3 seeds to start, the yield is so large that you don’t have to worry about running out. I got nearly 800 grams and that’s waaaaay more than I was expecting. Hopefully, I can grow this indoors next time, get an even BIGGER yield. Love PSB!

  30. KeepingitontheDL (verified owner)

    Ugh god work gets so stressful this time of year….I need a way to relax and unwind. FInally I came across this OG strain. I Love growing weed, have been doing it for years but this site…like whoa! I haven’t come across an online selection this big probably ever! I got my seeds delivered wicked fast and started them this spring in the backyard and they did pretty darn well….maybe like 1000 g in total from 3 plants? Like that’s crazy! If I ever do this again I’m gonna set up an indoor grow room….

  31. Fernando (verified owner)

    I am a Colorado native so I definitely enjoy this weed and have been smoking it for years now. I ordered my seeds online with PSB and got them delivered right to my door. Growing was easy and fun and I got some pretty impressive results. I am SWIMMING in fresh dank herb and this stuff helps me relax hardcore at the end of the day. Helps with stress, anxiety, and depression. Highly recommend!

  32. Lisa Rand (verified owner)

    This is an excellent west coast strain. Something beautifully delicious about this bud, and I love that it’s an even 50/50 split in terms of sativa and indica properties. It’s been really perfect for my stress and anxiety, this stuff really just balances me out, gives me a zen feeling inside, and I am floating on cloud 9 all day long. Perfect for a lunch break smoke, and keeps me interested in work until I am off at 5 lol!

  33. Chuck Cohen (verified owner)

    This is a perfectly balanced hybrid! It’s never too strong in the brain or the body, gets me stoned in just the right way and keeps me feeling good all day long! Was very easy to order my seeds online with PSB. A truly amazing company for how many seeds varieties they offer. I grew this weed in my backyard and got some nice yields. What a treat!

  34. Randall H. (verified owner)

    I suffer from depression and anxiety and find that weed is really great for my symptoms. I love this strain in particular, a very relaxing indica hybrid that’ll keep you feeling chilled out until bedtime. Definitely not a daytime strain, smoke this when you get home from work, it’ll help a whole lot lol! Fun to grow and easy to order online. I’ll be back for more!

  35. Donna B. (verified owner)

    A lovely strain of mj, very balanced buzz and it super relaxing. Have been growing mj for years, and this is not my first time growing this strain, however this is my first time with PSB, was very impressed by the selection of seeds and how fast everything shipped to my door! Grew right in the garden in my backyard, plants got nice and bushy and tall and I got a solid yield of around 450 grams! That should definitely last me a long time. I smoke anytime of day, but usually at night, helps me chill out and have fun!

  36. Elison E. (verified owner)

    With coffee undertones and a citrusy aroma, 303 OG is an absolute powerhouse in the weed world. Initially very uplifting and chatty, this strain slowly moves into gentle relaxation that can help manage stress and chronic pain particularly after a difficult workday. A very straightforward growing process, indoors I had a moderate harvest. I’d recommend this plant for beginners in terms of ease and quantity – the trimming cycle is painless, as you’ll be after you’re done smoking it too.

  37. Shawna J. (verified owner)

    My work requires that I travel extensively and often, so I’m constantly at the airport flying across the country. Only problem is I HATE FLYING!!! So to help me with the stress and anxiety it causes me, I thought I’d give the 303 a shot and what a relief! I smoke some weed before leaving home in the morning for the airport and getting through those long flights makes it SO much more bearable. I only wish I could smoke it right from my seat! Just kidding. The growing was a no brainier and I got nearly 300 G of nug to work with. Pacific is my go-to from now on!!

  38. Beth R. (verified owner)

    They claim this mj is 26% THC and I don’t doubt it. Seriously, the best bang for the buck I’ve found anywhere. Smokes easy, slightly sweet but mostly on the sour/skunk side. Can’t go wrong with this one.

  39. Jade D. (verified owner)

    I was the last person to think weed could help with depression. Here I thought for all of these years that it would make me more depressed. I think that was just before weed was legal in Canada and I rarely knew what I was smoking. Now I have all the information I need at my fingertips, and Pacific’s friendly customer service reps to help me find strains like this one. Thanks!

  40. Viviana I. (verified owner)

    Fantastic nighttime smoke. I have insomnia issues (I think due to a fairly high amount of stress in my life) and very few things can coax me into a restful sleep. I was so glad that I could find 303 online through Pacific Seeds as my sister has the same issues and she said 303 OG helps her a lot. Boy oh boy did it work for me too. Got me to sleep without any groggy feeling the next day. Only thing I wish is that the yield was a little bigger – it feels like I go through it pretty fast. Maybe I can find a way to expand my growing area and grow more weed …

  41. weezyl250 (verified owner)

    Had to have this on account of the fact that I live in Colorado. I had never heard of it before, which was weird, but anyway…. the weed didn’t disappoint. Very balanced high that is both relaxing for the body as well as the mind. I felt very happy and even keel after smoking this bud. My grow went pretty easy with no problems. Happy healthy plants the whole way.

  42. Naomie D. (verified owner)

    I have a very stressful work life and need something at the end of the day to help me relax and unwind. 303 OG is the answer to all my stress and anxiety problems. I really am glad I came across this strain! PSB has an amazing online selection and their delivery is both fast and discreet. I smoke this after dinner, when I’m ready to just chill out and unwind. This weed even helps me sleep at night. Highly recommend for 9-5 workers like me!

  43. Mateo J. (verified owner)

    I was resistant for using cannabis to treat my depression for such a long time. Now I regret all that time lost and wish I had tried 303 OG sooner. I wouldn’t say it cures my depression, but it does give me great periods of a happy high. It quiets my mind, eases my stress and even makes my body feel easy and calm. Not a bad grow, the plants were short and compact enough to grow indoors in my basement. Thank you, Pacific Seeds, and thank you so much 303 OG.

  44. Shelby M. (verified owner)

    I didn’t know where to buy seeds online without shipping issues but a friend recommended PSB and I couldn’t be happier. I ordered a pack of 303 OG seeds and they showed up in less than a week, no issues. Really great blend of indica and sativa with high thc so this is a perfect session smoke any time of day. Warmer temps kept this lady happy indoors and I got a modest but potent harvest after about nine weeks. I’d definitely recommend PSB to anybody.

  45. Hubert I. (verified owner)

    This is such a great strain. It’s an incredibly relaxing, peaceful high, without putting me to sleep like some pure indicas do. It reliably relieves my anxiety, which I’m always thankful for. It also arrived much sooner than I was expecting. If you’re looking for a good hybrid, you can’t do much better than this one.

  46. Natalie O. (verified owner)

    Colorado native here, so I wanted to grow a strain from my home state. 303 OG goes way back, I used to smoke this stuff when I was much younger and was super excited to find it available here at PSB. Online ordering was incredibly fast and simple and my seeds arrived in no time at all! I planted in the backyard and had some strong yield (around 300 G). Love the euphoria associated with this strain, and the burst of creativity is nice as well. Happy I gave it a go!!!

  47. Braydon S. (verified owner)

    I had some technical questions about this strain because my plants came out looking a lot shorter than I thought they’d be. I just contacted the customer service at Pacific and they were so awesome. The person I talked to definitely knows a lot about growing mj and he helped walk me through the ins and outs of growing this strain. Turns out my plants are just fine, but I might want to adjust my nutrients a little. Thanks for the advice!

  48. Vicente F. (verified owner)

    Easygoing grow for an easygoing high. This weed rules. Took ten weeks to flower but it stayed pretty damn short so space wasn’t an issue in my indoor grow which I like. Even though its a 50/50 hybrid the indica is really powerful here in terms of relaxation which is a really good thing, but it’s still nice and clearheaded and engaging. 10 stars for sure.
