heating your grow tent

[Dieselgrower]

so was wondering what you all do for a safe way to add a little heat in tent with LED lighting? I put in a cloudline t4 yesterday, seems great with humidity but runs in any of its 10 speeds usually slow so I lose my negative pressure to draw in heat? The room in my basement is heated by my central air(stays at 70) temp in tent was very low this morning, near 62 degrees. dont know if i should just cycle the fan vs using the auto mode but was the reason for buying.

I have used small ceramic heaters in a 5x5 tent and also a 3x3 tent. Both heat the tents very effectively. They have safety shut off mechanisms so if they fall over they turn themselves off. I think I paid $12 for a small one and $25 for a shoebox sized one.

Just keep adding lights will solve itself 🤷 that's what I've done, do this and control your exhaust to regulate temperature.

I have a small electric radiator at the back of my space, with a small separate fan blowing down on it from above. Works really good to get the temp up on windy days. Ive seen people who hang the same kind of radiator in the tent just above their air intake too.

That should do perfectly, do you have temp control or anything like it shutting off when it hits a certain temperature, just for safety's sake.

Plants are looking really good too by the way.

Thanks! Yes there is a built in thermostat that shuts off after a certain temp. Its a 10 digit valve to adjust heat so it took some experimenting to get it set right for my needs.

No radiators are efficient

Looked like a sales pitch to me too. 1st post, 3 yr old thread
