Ive noticed in these seedlings that they grow much faster under a color temp of 2700 rather than 5500. Seed 3 has been under a 5500 CFL and is by far the smallest. Seed 2 was the same way tell a few days ago I swapped it under a 2700 and now its growing much faster. Yesterday I put seed 3 under a 2700 for 3 hours and with in that 3 hours it grew more than it did in 3 days. So now Seed 3 is under a 2700. Seed 1 I put under my 68watt 2700 CFL 2 days ago.
They were all with in 1 - 2" and all running 24/0
