i am building 7 separate top drip 5 gallon systems
i am worried about stem rot and root rot
i plan to have a water pump in each 5 gallon bucket which will feed a line of nutrient solution from the bucket to the plant which sits in the bucket
i know i can keep light out of the bucket
eventually the roots will reach down into the bucket and the system will then have a deep water culture element to it
will i need an air stone to prevent root rot, or is the water pump enough water circulation to prevent root rot?
if the rock-wool cube gets wet from the top drip, will it cause stem rot?
