Stealth Speaker Grow Box Help?


420 Member
Hello My Fellow Growers,

I am currently in the process of building a Stealth Speaker Grow Box. I have the plans all drawn up on Google SketchUp (If you want the plans, shoot me a message and I can give it to anyone). Sadly, I had to downgrade from a 4'x4'x7' grow tent to a 17"x13"x48" Speaker Stealth. This will be used for a 1-2 plant supply. In my grow tent I used a HPS & MH Dual Ballast.

My question is: For this small of a grow, should I used a 150w HPS Ballast or a 300W Mars Hydro LED?

Both currently are fairly close in price on Amazon right now.

Any help would be greatly appreciated!

Hi, I have simular stealth grow box setup (15" W x 11.5" L x 32" H) currently using 4 100 watt CFL lights and have been constantly battling high temps. (+90 degrees). Also have used 150 watt LED and temps not much better. I am by no means an expert as am on my first grow, but would't a 150w HPS light produce a lot of heat?
