Whats with all the bro science when it comes to growing marijuana .... my favorite channel on YouTube is gardening in Canada, she's a soil scientist leave all bro ideas out the picture and go with what scientifically works AND why.
Some education reveals foilar spraying is 20x more effective than root uptake. I also foliar my cuttings with mycorrhizae (great white AND hydrogurard, fun fact I also spray my plants in soil with Hydro.
Here's a few results from my cuttings I noticed yesterday after being told
"Tell me you don't know what your doing without saying you don't know what your doing' for spraying GWand hydro foliar in veg only of course and all cuttings no mater the method I'm using.
This is tricoderma or mycorrhizae itself one of the 2 pretty neat the new forming root is SO insane micro small however my theroy via science not bro science came in handy even a microscopic root will become infected with myco which will in every area help you get off to a GREAT start.
I'm TRULY curious and will experiment with a clone ONLY foliar feeding a hydro plant on 0 tds RO water, I could be wrong. I will he trashed on for it however ima leave the bro science out and dig deep in my own research and trials and errors, this is a fun game the more toy research the more you'll know the better you can do.
OP comments, I've sprayed with a NASTY strong (7 habaneros minced in a blender simmered till you choke and cry when you put your face over the pot, it worked very well imo I agree doesn't work on pillers but any and everything else takes a death trip including YOURSELF just be aware spraying inside brother fans OFF safety glasses or shades SOMETHING on and wear a painting mask or some type air filtration deal. I used none of the above on my 2x INDOOR spray of this I learned VERY quickly to take my damn shirt off cover my mouth and nose and GTFO asap. Brother I didn't notice a flourish from the spray I noticed everything toast I'd be willing to say imo I felt it may have DRIED out the leaves slightly and or def stripped the waxy layer off them, that's the only downfall I'd noticed
