If it is 4 feet (including HPS which is already over $65, plant, pot) then you will not have enough space unless you vent that light and thus costing way too much for him. With $65 he's going to have to stick with CFL's. I suggest 55W(60W?) CFLs that cost around $30 each, one 6500K for veg and another 2700K for flower ( or check this out with the Saturn Bulb http://www.ezhydrokit.com/product_in...roducts_id=107 ...). Paint the inside white if you can't afford mylar.
stickygreenlightsabr Reviewed by stickygreenlightsabr on . Are energy saving lamps any good? Hi everyone, I was told that energy saving lamps work just as well as fluorescent tubes but thought I should come and ask the experts before I set them all up. They say they are the equivalent of 150w, are warm white and produce 2700k. The length of the actual lamp part is 4 inches, I've bought 6 of them and am planning to put them in desk lamps in an indoor shelf setup. What do you guys think? Rating: 5
