Experience w/ perlite drip irrigation
Looking for advice/pics/ideas on various setups utilizing perlite and low pressure recirculating drip irrigation. Small setups (25 plants) would work, but I would ultimately like to build one practical for a 48'-96' greenhouse/shadehouse.
Any setup including PVC, concrete, wooden troughs, etc would be appreciated.
I should add that I want to concentrate on tomatoes, and peppers.
