Friend,

A bit of advice?

You better get those lights within an inch of the top of the plants. Those CFL wont light a whole lot of anything....or get about 8 more of them.

Also, when you switch to flower, they are gonna run right up the HPS's ass.

You should start tieing them down right now.

They will triple in height when flowering and no computer fan is gonna let you get them close to that HPS.

Nice first setup effort but this will be doomed for failure if you do not plan for what I explained WILL happen.

Also, that HPS is mounted nice right next to that top....I hope you have some insulation between the light and the board.

Anyhow, nice effort just be prepared to work and rework your first grow or two..

Good luck.
