Grow room fans!!!!!

Yea I didnt notice how important circulation was until the room gt hot and my ladies became males or hermis

Actually there's nothing silly about using 12vdc computer fans to circulate air around the plants 24/7. I use 12vdc heater blowers from cars for intake and exhaust for positive air exchange, thermostat controled and a radial fan for the canopy while the hps is on.

One more thing, I have never had a clone turn male or hermied...ever.

Right HERE $20 on Amazon. The clip is VERY sturdy, clips onto almost anything.
