NFT plant spacing and pot size
I am intending to build an NFT system using 3m PVC downpipes and I was wondering if there are any experienced growers out there who might be able to suggest the appropriate hole spacing for this type of system. I am looking to squeeze as much produce out of these systems as possible so I was wondering how dense I can go.Also I am unsure of what size pots to use. I was thinking of using polystyrene cups with holes poked in the bottom as these are cheap and easy to get but I have seen pictures of people using really tiny net pots. I am going to use the system for basil mostly but might also try tiny tim tomatoes, strawberries, chard, lettuce and asian greens.
Thanks and take care:)
