yea im not sure of the grow bulbs, theyre organic growing lites from home depot with offlite or something, came in a yellow/orange box, but i got two of those going on a 19/5 schedule. theyre about 5 inches away from the light now, but the light has stayed in the same spot since they started. i have seen an increase in growth rate over the past few days, maybe because theyre getting more light the taller they grow? if thats the case then all i really need to worry about is when to transplant. any tips? (tomorrow is day 1 of week 4)
