Capping a rain gutter NFT channel
I want to use an aluminum rain gutter for my NFT channel. Does anyone have any ideas on how I can cap the ends of it though?
Also, I have a 75 gph water pump (EcoPlus 66) I was planning to use, since I've read that the solution in the channel should be slow-moving. Im using a 3 ft long NFT channel and will be putting 4 plants in each channel. Do you think the pump will be adequate, or will I need more gph?
