GypsyBush here, posting as Cali Cali cause... Ots a long story... Im waiting to get my old handle back...
I used to run a 4x 600w SOG on ebb flow...
before that, I did everything DWC...
you can do what you want, but in a SOG, there is a lot of work.... And the least labor intensive and more stoner friendly set up for SOG is ebb flow...
you can move the plants around to better distribute growth, since they are in pots...
you can clean out your res without fussing with plants... It's remote.... Plus you have ONE tank....
remember , the larger theres, the more stable it will be...
I used 2x 300 gal rubbermaid stock tanks and they stayed stable for over 2 weeks.... No water needed, no nutes needed, no adjustments... Nothing...
right now I have one plantmper 5 gallon bucket and ph needs adjusted constantly as the plants feed and grow explosively!
I LOVE DWC! But if I was doing a SOG, I wouldn't use that metod... Just makes more work for you.
and to touch on a touchy subject....
MY RES IS ALWAYS COLD, I LIVE IN A COLD PLACE... I HEAT MY GROW...
with that said, and the knowledge that colder water has a higher dissolved oxygen content....
I have had failures in both DWC and ebb flow... Ive had a water pump quit.... 18 hours + of lights on (2400w) and I could tellthey were stressed... But I was running straight hydroton... Throw some rockwool flock in there and you got water retention for 3 days+... This is fact, not fiction...lol....
I also had an air pump quit on me once, no idea how long cause I didn't notice it.... At least 4 days... Max 6 since that was when I changed the solution and saw bubbles.... No issues at all....
in short, if you want to do a for real SOG, go with the flow and ebb and flow... It will be easier and less work on you...
cheers!
