lowes has 70w HPS bulbs for about $20 each.How many should it take for a 6 plant grow in a small bathroom? (bathroom appx.5'x6')I now have about 500w worth of MH bulbs in there now for veg.growth but I will need the HPS when the flowering process begins. I'm thinking about getting 2 70w HPS's will this be suffecent?If you guys know a store where I can get them cheaper & maby more wattage I would appreciate that too.

i use a 400watt HPS on 4 plants
your gonna need a 600watter...rather than buying 120$ worth of 70watt bulbs how about going all out and get a 600watt hps kit?

been looking online at thoes high dollar HPS's & I'm kinda torn about how I'm gona light these plants ,maby floros mixed with a couple of thoes 70w HPS's

use the floros while in the vegging stage...and when it comes to flowering mix them with your HPS
