You are doing an excellent job with the plants and time period you had for setting up.
to be honest it could of been a disaster i had a friend growing a few orignal diesel and a few blueberry, the diesel was his and a gave him a few seeds off a hermie blueberry.
the box he built looked great and even had a fan and reflective material on the wall, the box was hot around 85 degrees - 95 degrees throughout the low-hot points in the day.
it had no ventilation but it had a fan so i didnt argue and the bud looked like it was loving it, the blueberry being autoflower finished first and it smoked really harsh and not potent but smelt good because of its genetics.
the diesel plants might as well of been reggs it came out horrible to say the least.
In my experience (where i live) the heat and high humidity dont work well, people say to grow around 75-80 degrees and around 85-90 degrees if using co2.
I have never grown anything that didn't have a good smell in the end but it really goes to show.
and he never wanted to put much time into it and definetly wanted to be putting less money than time into it.
Ive grown alot of really potent bud without nutrient lines i still wont be using it for this grow, all my other bud has come out really good organically i dont know i just appreciate it alot. I really dont know why lol.
Any nutrients it needs i can just give it to the plant in fruit peels or organic feeds, even the molasses has a good amount of potassium in it, im trying to flower a good plant and get good bud with nothing bud organic idk the idea is great = P weed makes a hippy.
