Okay, I'll hold off on the extra bulbs
I may consider it though come mid flowering time - I found some good bargains on fleaBay, something like 1.20 for a single 75W 2700k CFL
At that price I could get a fair few!
But...
I could otherwise get cracking on the LED upgrade instead, and buy some red ones instead of extra CFL's. I do have the space for them with the gaps between my bulbs, but probably a lot less hassle just getting more bulbs eh. Summer would be the best time for pure LED growing as there would be less worry with temps being too low.
Anyways, that's later... I'll hold off for the now
It will actually be interesting to see the difference in yields. You'd think that I'd achieve more with more bulbs, so we'll see what happens there
