Hello First year with hydroponics and using the halo drip rings. Was reading about the need for a wetting agent and the article recommended SM-90. I’ve discovered this is no longer available.
Any recommendations as an alternative to SM-90?
I found this on Amazon.?
Yucca root
I second that. I use RAW yucca. Pretty expensive per weight, but a little goes a long way.
@Glitch @Outlaw Thanks. I ordered some Yucca Root and will give it a shot
