Is it ok to fill me resevoir up use half the water feed the let sit for 3 days and feed again?
Is airstones a good idea in a resevoir?
I see its good to leave water out for chlorine gets out but then again u lose amount if oxygen in water is oxygen in water critical?
Theres no such thing as too much oxygen in the water.
Ive been growing hydroponically for over 20 years. Only small scale, 4 plants, just 100 gallons main tank, with another 100 gallon water butt to mix and condition the water before it goes to the plants.
Ive got two large air pumps. One to run 4 x 10cm dome air stone under each plant, the other with two curtain air stones down two edges.
When I turn them on I want to see a bubbling mass. Not enough oxygen to the roots leads to root rot, and a host of other problems.
Its so distressing to see one of your prime plants die because of root problems.
I mix my nutrients in a 100 gallon water butt which is right outside my grow tent. I run an air pump in the water butt as well, it helps with mixing, as well as keeping the oxygen levels up.
Mixed nutrients should really be used within a week, but Ive gone two. It didnt do any harm
