growing a batch of tomatoes
 

Hi Ron I am a beginner in growing tomatoes with hydroponics. I heard i few different things from people on what to do and don't know which to trust

I have been growing a batch for maybe two weeks i am using two different seeds of tomatoes. So far the big ones have a long stem and two leaves. I have been keeping my light on 24/7 and i manually water them twice a day using a pump to fill my tank from a reservoir. I always make sure the rockwool looks as wet as possible.

Keeping the light on 24/7 is that bad for the plants at all?

How important is a micronutriunt tester?

How important is a PH tester?

What temperature should I keep my plants at?

Any suggestions would really help me out thanks...

No

I can't imagine growing without one.

Can get by with an inexpensive test kit that I will be selling nest week. pH meters have to many calibration problems.
