1st post, CFL question

and if my understandings of physics is correct, those green pots that you are using as "reflectors" are ABSORBING all other wavelengths of the light that is hitting them, other than the green. that's why we see them as green. so any light that might possibly be reflected (which isn't much from a CFL) would be green which would be absolutely useless to your plants. so at best that pot is sitting there collecting heat.
again, where did you come up with this?
how can a CFL that puts out 1560 lumens provide the required 30,000 lumens/sq meter? that would mean that one CFL in the sq meter would be sufficient. not to mention a single CFL with the output of 1560 lumens can't put out 2800 lumens in a single square foot.
where did the 30,000 lumens/sq meter figure come from? i've always read/practiced a MINIMUM of 5000 lumes/sq FT is required. so with 10.76 sq ft in a sq meter that should give us a required total lumens of 53,800.
again, see above on lighting requirements.
i appreciate the eagerness to want to help, but after seeing your pics you really have no business giving advice to anyone. you haven't even introduced yourself to the boards yet, not that that is a requirement, but your first post shouldn't be bad advice. take your time, get acclimated to the place.
there are plenty of successful CFL grows around here. read through a few. if you have question ask. once you get better bearings by all means please return the help. that's why this site is so great....and kinda how it functions ya know!?
if you need some help with your ladies check out the plant problems sub-forum...............
On a serious standpoint, there is nothing shake didn't address amazingly. I just thought I would post to show my appreciation........?
Nah it was funny........
