The nice thing about CFL is you can pretty much put them against the leaves without burning them,.... well almost.


Your bulb to leaf seems "Maybe" a little close,... but you have 0 reflectivity on the walls of your cabinet.

Your sprout wants to grow tall to get into better light,... so give it better light,... put a splitter in there!

2 bulbs on a 45* vs the single bulb above will make that little sprout much happier, tho you will have to back them off just a bit to make sure you don't burn.


That's my take on it,... maybe there are some others that actually have a clue how to grow under CFL that might chime in here!
