a little help 4 a 1st timer. DWC H2O depth?

I have just started this little grow chamber I bought online, I paid too much but thats a whole other story. I know its very tiny but I am hoping to end up with 2 or 3 females and try and keep as smal as possible mayber with SCROG.
I started from seed as a 1st timer. I have been searching the forums but haven found answer to a couple quick questions.
1) should my 5 1/2 inch pots be set deeper in the container? (my six pots are in a 28 quart steriite container.)
2) How much of the net pot should be immersed in the nute soln?
hopefully i have attached a photo
thanks!

hey danlboy ,
in the first few weeks of life the water level needs to be high enough the bottoms of netpots are in the water maybe 1in. or so , so the water is sucked up by the hydroton n keeps rockwool wet . once roots are hanging down far enough they're out of the netpot and hanging in the water the level can be lowered .
peace

Thanks xcrispi. I thought so, will drain some out i filled it 2 about inches from the net pot...
also... any opinions on how this would work for a fogger? (it was included in the "package" )
