[Tempacc]

first off let me say i am not advertising this. the link is only so i dont have to take screen shots then resize. i hope its not an issue P.

I am wondering if anyone has used this system?

I have a 3.5ft wide, 3ft long, and 3ft tall. I have some Jilly Bean beans.

This setup has a 150w hps in the middle and 2 2ft T5 flouros on each side.
it is able 2ft long. very low profile.

1:How many plants to you think i could veg/flower under this system?
2:What about yield? and thoughts with this setup? (i smoke about 1-1.5oz a month)

a local hydo shop has this setup with bulbs and nutes..they quoted me $370. this, to me, seems like it might be the right solution for me...maybe not. any input would be appreciated.
