How much better would an econo 400 watt HPS
http://www.insidesun.com/Super_Econo...MH_65a26e.item
(if anyone could tell me if this is the wrong hps to grow with or anything please do..)
vs buying 2 85 watt CFLs and a 2 42w CFLs
for flowering 1-2 plants?
Im not looking for good or bad
I need to know what the pros and cons are and what im getting for my money
and does anyone know a way to calculate how much energy i would be using with hps vs cfls?
I mean its pretty obvious and written all over these forums HPS is BETTER I got that down..trust me... but im looking energy/heat/deal wise
oh and im growing in a closet with no vents in or out, its about 5x5 and its pretty cold around here right now, will the bulb heat be an issue?
if it is an issue can i fix it with a fan blowing across the bulb and maybe another fan venting in/out the door?
whats the heat diff from a 250w hps to 400w and for just 1-2 plants would a 250w be plenty and save me some energy?
thank you any additonal info on hps/cfl or otherwise is greatly appreciated
