flood amd drain

After you feed your plants using the flood and drain system do you check and see if the ppm goes down and add more nutrients to keep it fed at the same ppms? Whats ur thoughts on this?

Hello everyone. I’m very interested in building my own hydroponic setup for my next round. I really like the NFT setups. Could people please share pictures of there hydroponic setups that they have made or even bought ? I’m just looking for some ideas and inspiration. I’d really appreciate it...
