Totally awesome thread kamel!

I'm growing in a hollowed out wall unit. My dimensions are 1 1/3 ft deep x 2 ft wide x 4 feet tall----- 10.5 feet cubed 2 2/3 ft squared

i have two plants about 1.5 ft tall who are just beginning to flower.



With the low depth you can imagine that the plants are spread out width wise. (side by side) I'm using two 48" t12 40 watt sylvania gro lux tubes to provide light to the lower parts of the plant. They provide 1900 lumens each for a combined output of 3800 lumens of wide spectrum light.
Total - 80w 3800 lumens

However, only one plant can benefit from the tubes at once as it is arranged on the left side of the horizontal array with a plant in the center and on the right. For this reason the two plants switch places every day and are each rotated 180 degrees midway through the day.

above the plants I have two 14 w warm cfls, one 26w warm cfl and one 45w warm cfl
total 99w 6200 lumens

Total Total
169w fluorexcent light @10 000 lumens

is this 1 000 lumens/ cubic feet enough (5 000 lumens per square feet)

Im thinking of scrapping the two 14's, buying three new 26's, and moving the 45 w down to inbetween the bases of the two plants. This would mean that I'd have the 80w 3800 lumens of the tubes along the side, 45w and 2900 lumens at the bottom, and 104 w with 6800 lumens on top

that would give me a total of 229 watts and 13 500 lumens

That would surely be better, yes?

Should I replace the T12's with T5's? Are they readily available? Do I need to change ballasts? Do they come in 48"?
What are your thoughts?

Do you have any conclusive results for if 2700 k are better than 6500k for flowering yet?
