And no fan, cool!
I used the same Power supply and it shut down on me after 10 hours.

The Jackals look ready to flourish.:thumbsup:
Might want to pot-up before you do flower though.
I put some girls into flower in a DWC and noted a doubling of root size for the first 2 weeks of flowering.

At the least, poke some drain holes around the bottom.
Otherwise they sit around on their drain holes and stay too wet, yah?

Still, they look quite healthy so far.

Aloha,
Weeze
