Hi, I'd be interested in seeing them.

A PH meter is a must. A TDS EC meter is a good thing to have also but not as important as PH.
You sound like you got a handle on it and should do well.
The one biggest problem I have had is rez temps. If mine gets to 72 or higher nasty things start to grow.
Keep a cool room and hydro is the BOMB

The other worst problem is not hydro but bugs. Two-Spotted Spidermites from hell. Fought those bastards for over 3 years and poisined myself with azamax several times. Thought I would try mighty wash about 3 months ago. Well it killed them all and their eggs and larvae with just 2 aplications. getting ready to just spray for maintanace. And you can drink the stuff TOO !!!!!!!!!!!!! non-toxic to animals.
