Going to build a hydroponics tower need some questions answered
I'm trying to purchase some of my items on Amazon or another online company
Do I need or is this item correct and would you suggest another type/ brand...
1. HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range , 1 ppm Resolution, +/- 3% Readout Accuracy?
2. AcuRite 00613A1 Indoor Humidity Monitor?
3. And as far as ph -/+ goes is this an ok brand to purchase...
General Hydroponics GH1514 Ph Control Kit.
4. I also need the clay balls that go into the nett pots should I purchase these at Amazon?
Is Amazon the place to purchase all of these items for my hydroponics or are there other companies out there that have comparable prices.
Thank you!
