Got a 4x2 gorilla tent and I'm trying to make the most out of the room in there. I got a bucket from home Depot and I was originally going to do dwc with 4 large air stones, but it doesn't seem like I'm getting enough bubbles which I suspect is because of a cheap pump. I could buy a better air pump but now I'm debating just getting a sump pump and putting a line in a ring around the top to do aero or just get a new air pump. Or just put plants in it and see what happens.
Also this is for 6 small plants through flower.

That should be fine for 1 or 2 plants. What kind of airstones? Did you give them a 24 hour soak?Airstones need to be soaked 24 hours or you will get big bubbles. The smaller the bubbles the better.

They're still soaking, I'm pretty sure they're 4in cylinders. I was trying to do six plants, I'm not concerned on room, just bubble spread. Probably more like 3 to 5 plants for awhile until I get my cycle fine tuned. Also may consider boosting it up to 8 air stones

I use the cheapest pumps and only 1 stone per bucket. Water can only hold so much dissolved oxygen

Plenty of bubbles. Should be fine for 4-6 smaller plants

Can you give a minimum watt/gal ratio. New to hydro and was wondering. I have the Wal-Mart dual 3.5w and single 1.5w. Don't know flo rating.

Expierenced grower, New to hydro tho. Been watching your rail thread. Glad you came back.

Too many variables to estimate an outcome from watt/gallon.
You can use the same pumps but have different results than what someone on here is telling you.

A shorter airline will boost performance over a long airline running across the room.
A wood airstone, ceramic airstone, etc can be used to vary bubble size and flow rate.
The contact time between bubbles and water is also important - shallow vs deep water, agitators, etc.

I just bought an 18 w pump with 6 different tubes and that has powerful bubbles. The small ones never seem to do it.

Thank you all so much. I decided to run only 3 plants, they seem to be doing well. I'm also running a more powerful pump that I found in my heap of hydro stuff. At least I have a backup pump now.
And I'll make sure I look out WestDenverPioneer.
