Cataract Kush and Confidential Cheese are both flowering. They aren't quite as far along as your Herijuana, but they are definitely flowering.
My plants in the greenhouse have already reached the ceiling. I don't know whats going to happen to them, but I am definitely learning some stuff for next year. Also, since I can only water them on the weekends, and they are in 20 gallon pots, by the time I get up to water them, they are near dead from being so dry. This week is going to be a good test for them, I think if they can make it through this heat, they will make it to the end. The other thing I'm nervous about after reading other greenhouse grows is humidity. I have an exhaust fan, but I'm not sure if it will be enough. If you end up with a lot of humidity in yours, you can prob just take some side panels off to get the air flowing. Do you have ventilation in there? It is definitely something to consider for the fall.
