If you start more cuts and still have enough to try that again I would like to see it. Maybe put the 2 nutes in one row. rhizo-root ex-rhizo- root ex. That way you could help eliminate local temps,air movement, or other factors.
I love doing stuff like this I start with 120 cuts, I pick the best 64 to start narrowing down to 22. Of those 40 or so they are off to DR. M's experimental lab. Where I play with pH's,GA's and other plant hormones,enzymes etc. JK
Hey TG - no plans for these cuts - I've just thrown them together into a tub and am flowering them :)
Next stage is twofold:
1) Replicate the Root XL v Rhizo results
2) Root new cuts and then test half with AN Beneficials (Tarantula, Piranha, Voodoo) and the other half without - and then take a look at root development, maybe even flower size....we'll see...
