That's a very cool site! Nice selections all the way across the board. I may order one of those switchable NextGen lights, any light with a 5 year warranty sounds good to me! Kudos on the find! Have you ordered anything from them?
Ok so what will give me a better yield in the end. A 150 watt hps light. Or the 325 watts of CFL lights I have now.
Ok so now on to the pros and cons of hps V CFl lights.
hps light. pro#1: the hps light is easy to move if I have to ever move. pro: also its just 1 light insted of 8 cfl lights rigged to a shelf screen then hung by chains. con#1: It may get too hot in my clost and I don't have anyway to vent into an attic or anything like that.
CFL lights.
pro: they r cheaper than an hps light.
pro: they put off less heat.
con: I cant seen to get thouse rock hard nuggs the ppl r getting with an hps light.
Get an HPS and save yourself the trouble. You can get a 400 watt hps complete system for nothing these days. And your yeilds will be double!!
And you will have way nicer plants.
try costlesslighting.com you can get an 8 light t5 for 200 bucks they dont really make anything much smaller, you can build your own 4 light for about that price too though, at home depot. i only veg under these light though, save your self the hassle and flower under hps.
