Well they were in a window sill but seemed liek they were gettin t stringy so i put them under flurecent grow lights. Sylvania sun stick 5000k F/40 40W. at first i left the ligths on for a full 24 hours then heard that was to much so last night i turned them off and this morn i turned them back on. sorry no pics, i dotn have the cord. o theyre bout 1 1/2- 2 wks old and some of them are 4 inches but some are 1 so i put all the short ones on a seperate table and lowered the light so its bout 3 iches from them. the taller ones, the lights bout 4 inches from them.
