oldmac your spot on with those instructions!:thumbsup:

I've noticed my humidity has been way high for a few days. It's been chilly and warm... I've kept it at a level I'm happy with by adding a small fan. Just to stir the air up even if the lights are off. Low temps. were 68 lights-out. That'll change when we ever get winter??:stoned:
GaGrown Reviewed by GaGrown on . how important is ventilation? can it mean the difference between a healthy plant, and a dead plant? I know that people generally want to supply their plant with fresh air, but I would like to hear from someone with some real experience with that. Would a plant die if you kept it in a closed grow-closet, and only opened it every day or two? It's just that my intuition goes against the notion that plants can consume that much air. My intuition wants me to believe they consume miniscule amounts of air. Rating: 5
