Bro, in the vegetative stage, the plant needs between 400 to 600 ppfd for optimal growth.

Keep it simple, just lower the lights to 35cm. 480W is not too much for the room

Lights for heat- 24/7 okay?I really need the heat of the lights to keep the inside of my tent warm. To warm the air around the tent 24/7 would be expensive- much more expensive than using the lights all the time. But will this work with 24 hour lights? Will that stress the plants? Using auto flowers.
