Imagine the yield, that's a huge crop.
that link is redonkulous! I'm a going to try that down the road.
HPS would be best for yielding if oyu want larger amounts then go off with HPS
for me tough with my space limitations i use cfl's i got good yield last harvest of my 2 plants (4 oz dry) and no im trying with a new strain and well lets see what happends
also you save more money in your electricity bill with cfl's
