Funny you say that, I have several white russians that just sprouted and they are really lanky... I have a T5 light about 1.5 feet or less away. Its the 4 bulb 2 footer and they are really tall with barely their first set of leaves. I feel is I put the light any closer it will be to much for them.white russian for sure man i am growing one its not even an inch out of soil has 7-8 leaves already. i hadthe chance to smoke some a few years ago very potent shit.. my fav so far
