250w cab to 504 w cab

ok so i am running a 250 hps right now doing sea of green in homemade cabinet now i will be converting it in a grow or so to 504 cfl so i can double my plants i know i will lose some weight probally unless plants are kept 2in from bulbs but should make up with another 12 sog plants here is the cab and i plan to build the shelf mid way on flower chamber

here are some current pics of that grow above....these were at day 28 when the pic was taken...they are no more then 8 inches tall flowered straight from clone no veg

so i changed my mind again! i do this alot it seems! but this cab is new so i guess it is ok now i am going to buy another 250w hps for the bottom chamber so i will have two chambers with 12 plants a piece until i do a run with 24 in a lilttle bit smaller pots i want to figure out what is best with the same strain conditions and such. no need in wasting time and money when you could have more bud which ever way i get it works for me! the new 250 cannot be cooltubed though so i will have a separate fans blowing on the bulb and one on the plants like my current op
