K.I.S.S. works for me, I use cheap $5 rooting powder from home depot, RR and a cheap plastic dome. The only times I have had issues getting cuts to root has been due to cold temperatures. Even with the cold just about all of my cuts root they just take longer to do so.

I always have issues with coco. I always get plants that are deficient when I use it. At this point im staying with what works for me. I tired of fixing shit that's not broke.. I can also say that an extra air stone will help. With an areo or water cloner(domes are not used with these) I used KLN witch worked great when the cloners where working. Now I don't need to worry about any of that shit. Just cut my clone, Dip in Clonex, Insert into a RR place in the dome I'm done until I get roots..
only thing I ever put in my aero was roots excelerator and silica blast, never used a low EC nute solution though...seemed the yellowing of the lower leaves was a sign that roots were there or about to be. the stuff I've been using for my initial RR tray fill up is called "life cloning solution" my cuts have been coming out of the RR trays very vigorous although I am still experiencing the correlation of yellowing lower leaves to root being present...both methods have worked well for me for the most part...rockwool is a different story for me personally lol
also Dip'n'Grow has been a game changer for me, that stuff rocks. hands down better than any of the clone gels that I've used...and a little bit goes a very long way
If it does have nematodes it will pass on to the seeds. Bad nematodes are the worst
Can you elaborate?But this is the GG4 thread..so I won't talk too much about science and growing.
