Those look like my seedling, which is at about the same number of grow days as yours, probably a little more actually. I'm just using a 125 watt cfl, that's probably why your plants have grown a bit faster.
Crispyfried Reviewed by Crispyfried on . first grow!!!! This is my first go round with this so i thought i would start a little log!:) Day 12 for these little guys 4th day under 400w MH. Cabinet is 4'x4'x4' introducing outside air into cabinet with 6" furnace booster fan. With 120 cfm computer fan doing the exhaust work ( check out the temp ). The top temp ( in= room temp) the bottom temp(out = cabinet temp ). To me the temps seem ok but that dont meen nothing as like i said first go round :) Rating: 5
