you cant do it properly without the ac
except if you live in alaska or in a very cold spot year round
a minisplit is easy to install, they even sell small 2kw now
Exact
Crop steering will only work when there is substantial amount of media to buffer the water content fluctuations
With your method you better feed several times threw the day
I never said to ph the runoff
Just not to reuse it
0.5mS tap is not "full of junk"
It just contains some bicarbonates, which make it hard (calcium and maybe magnesium)
Depending on you location you can also have some sodium and chloride (beneficial in moderate quantities) and sulfur

hot climate (during summer) will also influence the heat charge to dissipate
