I don't comment much here anymore...but hey...the coffee is hitting me hard this AM...so thought I'd share my experience with GSC.... ;-)
Straight up.....it's your first grow. Don't expect to be slinging much weed about. Experience and >consistent< yields come with (much) time spent and the right strains and a dialed in room.
I only grew the Forum cut twice. The yields were poor. IMO...if you get an oz per gallon of soil in your pots you will be >>>>totally killing it<<<< with this cut. My yields were like 1/2 of that, FWIW...and for me...the smoke was only so-so. It reminded me of many plants I let go over the years that were sweet smelling and slightly minty but nothing special. Her only good trait for me was the FROST. She was definitely a frosty bitch.
Other than the low yield, the whole "well..you just didn't grow her right" (when she was in a room full of other strains that all performed well time and time again) turned me off on her for good. It was like growing Alien gear and not feeding them with the required feed schedule that was claimed to be "bred into the plant" and was reportedly (by some) needed for good results. What a fuckin gob of cum....but hey....there sure wasn't any shortage of swallowing here just the same...
I'm sure there's kill GSC out there. For me, the cut I ran (from a very respected source) just wasn't worth my time. I hope you have a different/better experience.....though as time has gone along and this cut has been whored out so many times...who knows if 99.9% of the representations truly have anything to do with the original?
Talk about a bottleneck in the gene pool.... in all my years of growing and forums I can't remember so many growers stuck on one plant for so very long.
good luck with your grow
