Exactly. ph, ppm,and temp are critical for any hydro setup.
I would avoid any submerged root setups in general. They usually stunt growth because the roots can't get the oxygen they need, even with air stones,
the growth is much slower than an aeroponic setup.
Here is a good poorman's aeroponic tub setup
If you stack two tubs, then using pvc to plumb from pump, up past sprayers, then back into res, the return line can be restricted, which will give you
the sprayer tip pressure you need, and super oxygenate the res.
The top tub drains through to the bottom through a hole, and the root mat gets to stay in a 50/50 environment up in the top
