Also, how high do you have your light above your plants? We started off really high, but now its only like 2 feet maybe. The closer the better, cause you lose like 1/4 of the lumens for each foot. Like a 1kw at 1 foot is 135,000 lumens, at 2 ft is like 45,000 lumens. They had a nice little chart in the grow bible showing how much intensity drops with distance, its crazy.

Light intenstiy = Total Light Emitted / ((4 x pi) x (radius^2))

And light intensity decreases by 1/x^2 where

So like if you have 135,000 lumens at 1 foot, you increase that to 2 ft, you it would be 135,000 x 1/2^2 which is 1/4 so basically one fourth of 135,000 = 33,750. Crazy huh? Thats why the top bud always is so big and the bottom ones are smaller, cause they get a lot less light. LST'ing takes that problem away, preventing you from having like 5 feet from the top to the bottom of the plant.

So thats the science behind bigger buds lol.
Splifted Reviewed by Splifted on . First grow log - 2-3 weeks into veg, need advice (pics) Hi, my first time indoor grow! I've been vegging under 4 fluros and 4 cfl's for a few weeks, they haven't been growing too fast, but I am happy with the way its going so far. I just transplanted most of my smaller plants into bigger pots, and switched it to a 400w HPS, with the 2 fluros on the sides. I'm able to maintain decent temperatures and have been keeping the lights on 24/7. I've been using FoxFarm Ocean Forest® Potting Soil (which has earthworm castings/guana/fish/crab meal), and Rating: 5
