Hmm, I'll see if my LED's produce enough heat for my grow area. I guess a fan heater would warm a small area pretty quickly, probably quicker than those wall units and might be safer than one of those bar heaters? Get one with the safety for if it falls over somehow, just incase I guess. Noted on the red light, didn't even think of that. Probably best to have the fan heater pointed away from the plants too. Do you guys leave your fans on inside your tent for air movement and circulation still? Sent from my Redmi Note 7 Pro using Tapatalk
