well i got 4 - 18 gallon tubs.rule of thumb is 1 watt per gallon, youll need more pumps and air stones, u should just get a bucket.
Is that the four outlet one? Do you have all four outlets hooked up the one airstone?well i got 4 - 18 gallon tubs.
what should I do? I got 1 18 watt 600 gph pump. it was the largest they had.
what happens if I don't up it?
yeah it's 4 outlet. i got 4 separate airstones for 4 separate tubs.Is that the four outlet one? Do you have all four outlets hooked up the one airstone?
they are LOUD as fuck. do you think adding another one will make it much louder?I think you should pick up another one of those pumps and add another air stone to each rez
what about just spraying the rockwool? the roots were already in the water from 4 days from napkin. the seeds just exploded. it was about 8".This all depends on what you want the bubbles to do. If just oxygenate the water then that may be enough. But unless you have another way of feeding them until roots are in the water, it is not nearly enough to be bubble based. I use that 600gph pump on 3 12 inch stones in 6 gal of water.
If you are worried if the rock wool should be soaking or just moist it is best to just let it soak. Many people have accomplished it and I am right now. rock wool will hold as much air as the plant needs for it to get past seedling. If it needs some lower it will transfer air from the top and sides of the cube for it. I can take a few pics and show you.
