303 OG

As its name suggests, 303 OG marijuana seeds do indeed come from the Colorado area. Because these seeds are so locally based, they can be hard to find outside Colorado. But if you do ever come across this strain, do not pass up the opportunity to bring it home with you. 303 OG is often referred to as a medical strain for its ability to help fight depression, anxiety, and stress disorders. Indicas, in general, are effective ways to relax, unmind, and melt into the bed for a good night’s sleep.

The wave of 303 OG comes in two sets. The first feels similar to a sativa, as you’ll be more social, creative, and engaged in whatever you’re doing at the time. The second set, however, is when the medical feelings come in. If you had a long, stressful day, the second set of 303 OG will make you feel like you’re floating on Cloud 9. All that stress and tension will rapidly melt away and your mind with quiet down. 303 OG also comes with a euphoric feeling, which is particularly effective for smokers with depression.

Many consumers are in agreement that 303 OG marijuana seeds have helped them through tough times. For those who frequently suffer from panic attacks, it might be helpful to keep this strain around the house to lower your heart rate and calm the nervous system. This strain does not trigger any symptoms of anxiety or paranoia. Many choose to smoke 303 OG at night.

    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.

    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!

    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!!!

    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.

    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.

    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.

    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!

    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.

    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 …

    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!

  11. 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.

  12. 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!!

  13. 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.

    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!

  15. 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!

  16. 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!

  17. 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!

  18. 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!

    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….

  20. 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!

  21. 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!

    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!

  23. 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!

  24. 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!

  25. 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!
