What size do I need?

I have a cabinet that I've used for a CFL grow, that I'm considering converting to HPS. I've got 3 CFL grows under my belt now and feel it may be time to make the switch. The cabinet I'm using measures 52"h x 20"d x 28"w usable space. I only grow 1 plant at a time, as it's just personal.

What would I need to put into that size cabinet, a 400w ballast? (or is that overkill?)

For reference my last CFL grow I used 2 huge 105w CFLs and a couple of normal 23w for spot coverage.

Would my current extraction fan that's rated for 265cfm be sufficient for a HPS setup in that cabinet?


Thanks for any input!

get a 400w dimmable ballast that way you will be able to lower the watt if it get too hot and if you decide to change for bigger space youll have ehat you need
