Hey Crispi,

Thx for the pics and 'splaining how it flows. I have a couple weeks to design and build my DWC recirc and I'm following the same principles as you did. I'm running a Sunlight Systems 430 HPS in a 3x3x6.5 tall enclosure. Venting with Vortex 449 CFM inline with a carbon filter scrubber in the room to treat air before expelling outside.

Gonna go organic with the Pure Blend Pro + Karma + Zone (root cond.) + a little Sweet as long as I can keep PPM where it needs to be. By the time this gets going my gal will be back in town and I'll have my good camera to start a log and share pics.

I think I might end up going with the 2.5 or 3.5 gal. buckets to save space since the 3x3 is enclosed and I hafta keep the res and buckets all inside the area. Should work fine during fall/winter here and then I'll have to modify for the damn hot summertime here in cali.

Thx again for the help bro, its more fun when I can get ideas and keep from makin mistakes... gotta make every dollar go as far as poss.

Peace
