Hey bud-ies! I was wondering how many 16 watt 6500k, CFLs to put on a 3 inch tall plant. And how far away to put them. Any ideas? :confused:

One or two on a 3" plant should be plenty, I think . . . as close a possible w/o touching the foliage. While it's tiny, maybe put a reflector under the planter, or around the bottom of the stalk.
A sheet of mylar, a mirror, foil, etc.

Thankyoou! One other thing. All of my leaves are slightly yellow all over. Is this a good time to start using nutes?

well heres how it all started. at first my soil had a npk ratio of .07 .01 .03. with that all of the bottom leave tips started turning yellow and then brown. these would then eventually just fall off. i flushed my soil about a week ago and now all of the leaves, not just the bottom ones are turnng slightly yellow. not near as much as the tips from before though.

If a person doesn't have access to mylar, foil, etc. mirrors are much better than nothing. The concept of mirrors "eating" light is utter non-sense. It reflects in the 70% range, where as mylar is in the 90+ reflective range.

Place a mirror such that a beam of sunshine reflects off of it and thru a magnifying glass . . . now, hold that magnified beam on your flesh and tell me how mirrors eat glass . . . before it burns you. Total myth.
Were it not, I really doubt they'd include a mirror in all complete survival kits.
