What size grow tent should i get?

A question of a fellow grower:
Im in the process of setting up a small grow room, i wanted to have everything in place before i order my seeds. My question for you is what size grow tent should i get? at this moment im using a Sun System Grow Light - HPS 150W Complete System with Ultra Sun Lamp. I hope that will work. I plan in the future to upgrade to 400W HPS. looking forward to your responce. Thank you very much

Im thinking a 3ft x 2ft x 5ft room. hoping for 2 or 3 plants. going with autoflower seeds. any suggestions would be appreciate.


A 400 watt hps light is pretty good in a 3x3. I would consider going with air cooled, should help maintain environmentals.

Im stuck with a 150w HPS and hoping it will do for now. what should i expect for growth with this light.

I can give you a good website for a grow tent they are very good and don’t cost so much if you want too :slight_smile:

That would be great. Thank you

Yo here,
https://www.growmart.de/Growboxen-1.html in my opnion they are pretty cheap and still good i have the l one. You can also buy complesets but i would recomend buying the complete set and then had not the things i wanted. Trust me

3ft x3ft is a nice size tent for 2 plants. I would consider going 6ft height if possible to give yourself room to tuck in the exhaust fan or circulating fans tiewrap up cords Etc. Good luck

not much, the low watt HID’s (under 400w) r pretty in-efficient,
150w HPS will cover 2-3 sq ft in flower, 1.5’ x 2’ area at most,
this is better then most Blurple LED tho.!!

try to grow one plant under it and save up for better lighting.!

3x3 tent or 4x4 tent. You can grow at least 4 middle plants in this size.
I have used MarsHydro tent for a few months. It is well-built. I like the metal frame structure with the affordable price.
