:jointsmile:Currently I am growing just 2 plants. I am a legal MMcard holder.

I am using 4 48inch Fl tubes in both ends of spectrum. THey grow ok but from reading here I see metal halide is better.

So I went to Lowes, they sell 250 and 400 watt MH bulbs for 29bucks.

However they do not have ballast.

What is the cost if I bought a ballast kit or already made box for bulb and where is best price in your experiance?

Or is it more cost effective to built my own box with ballast?

Lastly, I only plan on 2 or 3 plants max. No over kill needed. Is one bulb enough for this? Would I want to use my FLor tubes as well?

Thank you.
