well the fan just simmulates the wind in nature and i guess its almost like a human muscle....the more light stress it gets the more tone it gets.....IDK...but a fan is a MUST. I know you maight be stressed on money but i made this into a grow box and it looks bad ass....im thinking of getting another one....one to use for veg and one for flower...


Workforce 30 In. Base Cabinet - $54.97 at Home Depot

it isnt very tall but i needed something small and compact so its perfect.

also i used this link for topping:
How-To : Fimming and Topping made Easy - Grasscity.com Forums

and this one helped explain LST:
How To LST (Low Stress Training) - Growing Marijuana
