Hey 4x5,

How many days into your grow did you start 12 & 12 when you were using just fluoros. I'm using 8 x 48" cool white tubes for veg. for now. I got 4 GE Plant & Aquarium tubes and I was going to get 4 more and use them for flowering but they're 1900 lumens and I can't find the temp anywhere on the packaging. If warm white tubes have more lumens I might try 4 of them along with the GEs for flowering. Did you change light temps with fluoros?
