These plants are by far the biggest most badass I've ever done. I'm cloning all females of course, but my guess is I'll only use clones from the two biggest bitches. The central stalk is as big around as an air hose, the kind you use on your huge air compressor with air tools and shit. I pruned up until 7 days into flowering (yesterday). So there are ~8 branches per plant, all the same height. They're as big around as a kindergarten pencil LOL. I pinched alot during the last 3.5-4 weeks of veg and topped them. I've personally found, that the style I like the most is topping near the end of veg and pinching, then using all branches that aren't going to produce heavy for clones or trash. With the pinching and the topping, they were an average of 21" tall when I switched the flowering. They are massive. The 4 in the middle are in Home depot 5 gallon. 2 are in 3.2Gal dirt pots, 2 are in 4.XGallon pots that some pool stuff came in. I've never grown INSIDE in anything over 2 gallon. I had some in 3 gallon last grow I was doing, but I had to move them outside. They've shown absolutely no signs of deficiency in any way. Been flowering since Jun 25. I will start watering with Advanced Nutrients mixed in the pH balanced water once the soil is dried out from last watering. My partner found our camera in their car YESTERDAY, so next time I'm over there I'll get photo's. 8 females. I hope for a pound of dried bud. I'm crossing my fingers.
Do you know the strain/s your growing? What kind of light are you using? How much grow space do you have? It sounds like you have pretty good expectations from this grow!
