Undrilled and with indentation to fit tight and support. High density material, does not break up like polystyrene. Can handle 20 kg of vegetables floating on water. Very durable with many years of use.
Drill holes with 44mm drill bit cutter at desired distance for selected crop species.
Care: brush with a gentle plastic brush to remove debris. Use a soapy solution to remove stains left from plants, then rinse well with tap water. Use a bottle brush for cleaning the inside of the holes with the net pot and plant sits.
NOTE: When drilling the holes, keep the studs to act as plugs when holes are not in use, this prevents formation of algae in the system.
