wow thnx for the quick response.

When you say your carbon filter are you talking about a manufactured one or a home made one? and how do i know the m3 per hour?

on a side not. i got some 6500k cfl's because when i was at the store i fergot which was the "red" light. i just moved my plants to bloom and changed from 3x13w 3000k clf's to 6x23w 6500k cfl's.

My question. can i make do with the 6500k for now? or is it really important to get the other spectrum?

btw the plants look rather health. n my first grow so i'm stoked
