Things to know about lighting

i figured out my light output according to the info in post #1 of the thread linked above.

minimum lumens/square foot: 3000
ideal lumens/square foot: 7000-10000
HPS: 107 lumens/watt
CFL: 65 lumens/watt

i have a 1000w HPS, 4 23w CFL's and today i added 2 28w CFL's.

1000+(4x23)+(2x2) = 1148 combined watts

(107x1000)+(65x23x4)+(65x28x2) = 116620 lumens total output

my room is 5'x3.5' but the back 1' isn't grow space so the lights only need to light 4'x3.5'=14 square feet.

116620 lumens in 14 square feet = 8330 lumens per square foot

when its time to flower i'll rotate a uvb reptile bulb around in each hanging socket for a while. hope i have the cash by then for 3000 bulbs.

also added another air pump and 2 air stones in each dwc tub for more air.

still need to bring my humidity up.
