Hope this is the right sub-forum for this question.
Having had a lot of trouble trying to successfully create clones,
we sprung for a TurboKlone - the 48-site version. Our first attempt
with it was sloppy, the cuttings didn't root, and the tank, pump,
manifold, and nozzles all got gummed up with algae. So we decided
to get rigorous about it.
First we gave everything a good flushing with with tap water to clean
the visible algae out, scrubbed out the inside of the unit, and gave
the neoprene collars a boiling-water bath. Then we ran a 10% bleach
in tapwater (our water's ultra-hard here) solution through for 24
hours to sterilize it. Then we dumped the bleach/tapwater and replaced
it with store-bought RO water (pH 7) to which I added 100ml of 3%
hydrogen peroxide, because that's what I had handy. I based the
concentration on the recommendation in an article I'd read to use
1ml/gallon (sorry about the mixed units...) of 35% H2O2, and the tank
is about 13 litres, so the math works. We ran that for another 24
hours before we made the new cuttings from our fat and happy mothers.
We used a sterilized blade to make the cuttings, and immediately
immersed them in the clean (bottled) water in order to prevent air
embolisms. Each cutting then got a little dip in Wilson Roots IBA
rooting gel before insertion into the collar. Then we put the dome
on and put the unit directly beneath a pair of 4' 40W Sylvania Gro-Lux
tubes. They're T12. Everyone talks about T5. Does it matter?
After a week, we had no new roots whatsoever, so we started to look at
the variables. B'cuzz Root Stimulator had been suggested to us, so we
added about 12ml as directed. Also, we thought water temperature
might be an issue (it's running the basement where it's rather cool),
so we added a heater to the TurboKlone's tank to bring the temp up to
75F. And since everything we've read says that we should be a little
on the acidic side, a bit of phosphoric acid was added to bring the pH
down into the 6.0-6.5 neighborhood. Finally, we'd been told that the
rooting gel is a bad idea when trying to do aeroponic cloning because
it clogs the cut stem. We'd actually been concerned that the constant
spray would wash it off before it could do its work, but I guess that's
not the case. So we added the specified amount of cloner liquid (2ml
of a .6% IBA and .1% B1 solution per litre) to the tank and recut the
bottoms off of a bunch of the cuttings. Another week's passed, and
pretty much everything's dead.
Oh - and I should mention that we're running the lights 18on/6off.
So we could use some guidance. I suspect the first go-round wasn't
quite right and that the cuttings were already too compromised by the
time we tuned things up and recut them, so we're ready to clean it
all out and give it another go. But I don't want to do it until we've
gotten opinions from the experienced hands here. Anyone?
Thanks much in advance.
