Looks like you're off to a great start! As far as light cycle goes, if they're autos, it shouldn't matter. I've heard of guys experimenting with all kinds of cycles, even 12/12, although I think that would reduce the yield. Like you, I went with a 19/6 cycle, and my Think Different seems to be doing fine. I might be wrong, but I've read that co2 supplementation helps the plants deal better with high temps, so you may wanna look into that. My temps are usually in the low to mid 80's, and my plant seems to be doing fine. I use a co2 Boost Bucket. The Dutch Pro nutes seem to have worked well with my plant, so I think you will be more than satisfied with them
Thanks for the feedback dude,
Good to hear your think different are going well.
The room im using for the grow is essentially just a bedroom with the hot air getting blown into the rest of the house through the open bedroom door with a large fan.Not sure how well co2 will work that being the case but for sure will try to read up on that tonight.
