seems crazy.
I had a 15 gallon with nothing but a 50/50 65 watt compact and grew just about everything in it.
Guess I was just cheap and lucky....lol

70 or 150 would be my choice but then I am running 250 on 25 Gal.
You would probably run hot so you might have to get a chiller so another $300 :wink:
With pc you are limited and T5 you are 24" for the smallest so MH is your best bet. My two cents.

I would try a compact and then upgrade if you find you need to.
i think you will be pleasantly surprised.
