Well, I disagree. I grew 8 OZs from one plant in that little bubbler, An 8-9 ft giant that I had to bend over to keep it away from my light. Hey you can always get another air pump I had 2 air pumps and 2 of those 6 holers going and ended up with two giant plants, the second large plant netted 6 OZs of dried bud. I harvested a couple of smaller ones earlier, plenty of air and 4ft long roots all curled around, They are great for a first grow and you can always add an air pump and more stones, A little 1/4 drill and Viola another airstone added. I think I paid 12.00 at a fish supply place for the second pump. it was about twice the output of the original, so I got a three way manifold and split it up between the two bubblers. The first grow I did, I only used the original pump and got 10 OZs from 2 plants in that single bubbler.I have to speak up here, I do not believe that the tiny little air pump that comes in that auction on ebay is suffiecient for the 35+ gallons of water in that tub.
You need 500cc of air per gallon per minute. minimum, I use 2500+ per Min/gallon.
That air pump only puts out at MOST 2 LITERS of air/minute. Its good for 4 gallons of water.
You would need 5 minimum for the tub and the plants to live/.
