is hydroton needed? or can i just use net pots and neoprene collars to hold the stalk in place?
also how can i equalize air pressure in a 2line air pump, if each line is split into 2 again for a total of 4 lines? it seems each main line is pushing out only enough air for 2 of the 4 airstones to get the bubbles going.
