I am almost ready to start flowering my blueberry and my purple widow. They are doing great i cloned a couple days ago and LST'd the widow (it was outgrowing the bb). Now i have it under 24hr darkness before i begin to flower. My question is how far should i keep my hps250w away from the plant at this stage? any help would be appreciated. Oh by the way its a dwc and it is well ventilated.
