  1. I grew 9 GSC plants in 2020 in upstate New York, Beautiful plants and very high Yield at 7 lbs. I am growing 8 this year. 2 hit smoke stoned half the day, very good smoke.

  2. I have been growing the Original GSC outdoors for 6 years and have had nothing but success and rave reviews about this strain. If you have the right climate and weather and put the time and right ingredients in, you end up with a great product. I live in the Foothills of the Sierra Nevadas in California. If you grow right there is nothing like Outdoor cannabis. I have never had a GSC under 9 1/2 feet tall. My tallest was 10 1/2 ft. and never harvested under 5 1/2 to 6 lbs. on a plant. One year I only had 2 GSC plants and they averaged 10 lbs. per plant. That was the most I ever got and the growing conditions were Perfect that year. I usually have maybe 8 people, (regular smokers), test my strains after it is dried, cured, and trimmed and have always received rave reviews on the GSC. Keep in mind, this is the original GSC, not Thin Mint (which no one seems to like much), or the other phenotypes. Also, you have to harvest your product at the perfect time to get the perfect product. It takes a lot of time and a lot of money to produce a great harvest. I don’t believe I will ever stop growing this strain.

  3. I currently have a girl scout cookie in Vegetive growth soon to go to flower and im wondering just how much she will stretch during the first 3 weeks? I’ve heard GSC is a big stretcher so would like to know what to expect? Thanks in advance

  4. I am growing a clone of Thin Mint from 2016 Cannabis cup winner from Larry OG. Now working with his strains. I have a Larry cookie from this and going to re breed it back to the thin mint.

  5. I’m in my 3/4th week of flowering with my GSC …we are going into Sept. here in MI, cooler nights actually seem to be advancing my potted, outdoor plant that I began as a seed, told to be GSC? She is very sturdy and keeping pretty healthy from what I’m able to see and know, as I’m a first time grower. Buds are forming very nicely, although again, only in 3/4th week phase of flower. Plant is a potted version, combined both soil and cocoa mix. Use of occasional Epson salt in watering seems to be doing well. The plant is roughly 4ft tall from base to top stem, and sturdy. Per count I have about 17 ‘arms’ in budlet stage. So I think my yeild should be pretty descent! Keeping fingers crossed that temps stay +neutral, although I can bring plant in if need be. I’m a first time grower, Grandma, and Stage 3+ Colon cancer survivor of 9 yrs now, alleviating use of all pain meds and others that chemo did to my body and advancing stages of different ‘ailments’ that we’re to come at later days in my life. Hoping all continues on right healthy course with this plant and I can provide even more positive writings to you, about it, in the future. Keeping fingers crossed! Mamajacs in MI

  6. I have recently jus invested in equipment to start my own grow. I put 20 beans in to germ and all 20 sprouted. Inga someone over seeing me cause it’s my 1st grow and unsure of all that comes with it. Long story short I was miss guided in a big way and almost cost me everything. The seedlings I feel went into light shock. So I’ve read and read and read and got them to come out of it, but I’m unsure of where to go from here. I’m afraid of losing the crop or not getting the yield I want. Unsure of what to do and afraid of losing my investment. Do I try and save the plants or start over? I have plenty of beans left. But the timing will throw everything off! Lost in Ohio! SOS

  7. Two years ago I grew my first crop. It was 2 GSC. We weren’t legal until July (Oregon) so that when I started with 2 small clones. They did great. We had a late, hot fall and they finished around the 10th of October. Came out real good. Last year, I bought two small GSC clones, then took cuttings off them. Shared two and kept 3 so total of 5. Wet fall came early and made it tough to finish. I have them on low carts and pulled them undercover if it even looked like rain. Kept a couple fans on them whether inside or out because of humidity. Was a hassle but had a big crop and no mold. This year I have added blue dream and cookie Viper to a couple GSCs…

  8. Girl scout cookies kicked ass outside for Me. I averaged 3 pounds per plant. Grown in butte county California
