WH I thought yer farm had bubbles...I think having airstones helps I added one to my res halfway through my first run...I don't think ya need a huge air flow either to do the job I use a 10-30 gallon fishtank airpump that's only 3 watts my 20-25 gallon res units and that bubble cloner...the airstones diffuse the oxygen in the water so the pump sprays a half oxygen have nute solution mixture

ok so the hydroton test is done and the youngins are in...basically with 4 gallons of tap at 150 ppm the water would rise 1 point each day from 5-6 for about 3 days and a little the next 2 days I recently ran water over the net pots showering the hydroton for a while before puttin it in the tank and that seemed to seriously reduce the ph issue while eliminating soak time

crispi's on to somethin with lettin em get bigger too I'm a believer

air ventilation improvements have helped growth :jointsmile: the recent heat forced me to vent through the new light and out the room...it goes filter to light to fan out of the room the light itself both frame and glass run cool to the touch closest I can get it now is 1/2 a foot

not sure how much more I'm gonna get this time but it definately looks much better

you startin to see color change on the girls yet WH?

PS horror business a 250 hps if run hydro for like 10 weeks flower should get ya bout 4z's if the setup is ideal but even with some problems you'd def break an ounce
