how to heat a small 1mx1m box - Growroom Designs & Equipment - International Cannagraphic Magazine Forums

Invisible Rasta · 12-29-2017, 08:46 PM

hello guys, i am setting up a small box with led lights and i notused that since the room is very cold (10-14C during the day) i will need a very small heater. What do you guys suggest?I do not want a 500-600W heater as it is way too much and consumes way too much energy. I could build something if u guys have any good ideas

I wouldn't waste money on heaters before trying a 600w hps. Heat and ample light in one package. LED don't produce enough heat in cold conditions unless they are drawing a considerable quantity of true watts.

use a seed propagation mat under your pots. It will make the soil warmer and raise the ambient temp some

Maybe a small tub filled with water and an aquarium heater will give you want you want.

If you can set your little grow box as high as possible in the room as heat rises.

Unless you can bring the temps to at least 20C the plants won't grow fast.

Is this box only 1m high? If so my suggestion of a 600w hps is obviously not suitable, but a 250w might help, combined with a heat mat as suggested by ronbo51.

Yeah a 250 will heat the shit out of it.

I have a 200 watt aquarium heater for my 90 gallon aquarium and you can dial it down.

Once the water gets warm it will keep his grow box warm I bet.

Your heater looks like about the right idea, you should be able to find a plug-in thermostat somewhere, I never used one yet but I think they're becoming more common.

I think - maybe, this

Then this - https://www.amazon.com/bayite-Temper.../dp/B01KMA6EAM

I'm not sure the one you showed is naturally going to switch 120/240 is why I'm kinda saying... Uh...

I looked on the questions being asked for this one, and the people say that it's really designed for a brood box, this kinda thing. I think it's real, because brood boxes, those are peoples' livestock birds so you probably have some decent features with this, I dunno.

Maybe like this one? It's cheaper, seems pretty feature loaded, you can get it Prime:

Oh I found this one too: NINETEEN HUNDRED PEOPLE bought it so it's probably ok for general usage:
