Sup ,
Get rid of wrappers , bury in hydroton deep enough that the top of the cubes covered so algee doesn't grow on top of em .

Next grow look for 1 1/2 in sq. starter cubes w/o indiv. wrappers , they come in a sheet all attached . They are not as dense as the wrapped cubes and can push roots thru cubes twice as fast .

Airstones will help oxygenate the res and the water thats forced up drip colum/tubes . Your roots will eventually make it into the bottom container w/ airstone .

Look up waterfarm dwc club thread by Bluebear .
Tonsa good info.
Peace
