Ph controller is the best thing I've bought in years

I’ve been growing hydro for about 4 years and adjusting ph of the res is just a part of it. I found this gem on Amazon for more than half the cost ($160 all in with tubing) of blue labs controller.

I really wish I would have done this long ago. Makes things so much easier.


Wowza. It amazes me about this stuff that people come up with.


Exactly what I’ve been shopping for. Thanks!

You have to make your own hanger. It comes with a hanger made for fish tanks. It is nice not to have to go in and add 50ml every day @yourviolentpast
