hi i just started 4 plants recently.they are 10 days old. im using two 19 watt cfl's and distilled water two seem to be darker than the other two. they got pretty long which im sure is from incorrect light but im broke lol though they seem to be growing well. the actual weed leaves are big and each plant has 2 sets.im just wondering should i just put soil an 1 1/2 inch to two inches below the leaves or stake them. the pots have plenty of room for more soil.
