i have to use a fan at all times when the lights on as it gets too hot in there,its close enough to make them sway slightly,was a bit worried at 4-5 days would be a bit early for a fan but had no choice with the heat factor,gave them first watering this mornin since potting them on thursday,gotta keep an eye on it daily to get used to what water they need,not sure if every 2-3 days would be enough??
