cant lie to ya,no co2 meter. made the thing out of 6 in. pvc pipe, it was a u tube project..will post pics of it when i can. the cfl's i am going to chane to full spectrum, just used those to see if they worked. used old fixtures from house remodels.most of the stuff i had laying around, like i sayed in a earler post [kinda handy].the room came out about 8.5 long and 12.5 wide overall. they seem to be really happy this morning,even the clones i took yesterday, havent even drooped. :hubba:
