I am considering building a nutrient film technique (NFT) hydroponic system. I read this project and found it to be really informative. I have a few silly questions. Hopefully, I can get some guidance.
1. To connect the water pipe, which is the most suitable PVC glue or solvent Cement that I can use? I read online that there are a lot of types of PVC glue. I am not sure which one can be used for drinkable water.
2. Are all those stormwater pipes safe for drinkable water? If not, what's the best product I can find from Bunnings?
Any help is appreciated. Thanks in advance.
Cheers,
Ricky
