what bulbs are you planning on getting 10K or 20K bc i have 3 250W MH i just took off my tank for the T5 conversion i just completed.. and they are for sale with 6 bulbs (1) dual (1) single PFO EYE ballast and 3 iwasaki 3 ushio bulbs... Spider reflectors and sockets Problem is the ballasts will only run those two types of bulbs.. however I get around an inch of growth every couple months
