Hi, First post, I'm Leon a retired Australian living in Davao philippines. Am building a system for Tomatoes and hopefully a few Strawberries.

First I should say being where I am it's very difficult to just drop into Home Hardware or Bunnings to purchase what ever I want so it's an exercise in adapting what I can get to do the job.

Question, I know from being involved with raising Trout fingerlings that Zinc from Galvernised fittings used in the system would kill the baby Trout.

My first thoughts are it won't be a problem with Hydroponics however you never know. So is Zinc or using galvernised fitting in the system a problem?

Building a flood and drain system because it gets hot here and my thinking is the plants will get more oxygen during the drain cycle and the trick will be to let the roots get plenty of air without drying out.

Couple of pics of my system so far and it's a work in progress.

CIAO Leon..
