I’ve finally found a successful method (for me anyways) of coaxing a very young/small apical meristem (top) to root.
I have a bunch of glass yogurt jars laying around from one of those yogurt maker kits.
I realized that common foam collars fit perfectly in these jars. So I took a foam collar and filleted it to make it half as thick.
When I topped one of my plants I decided to give this a go.
- Fill the jar with RO.
- Snip the top.
- Dunk directly/immediately into Clonex.
- Collar the top; pop it into the jar… it floats on the water but also provides a bit of a seal at the threaded neck of the jar, which turned out to lessen evap by a great margin, even on a heat mat.
Surprisingly (or maybe unsurprisingly depending on who you are), after about two weeks with no changes to the water, under 18/6 on a heat mat, I have this:
It’s obviously not a production method but it was “too easy”, considering this top was really short, taken just above the 5th node early in veg.
So yes you can stick it in a glass of water and get the same result… but this method seemingly allows for a much more delicate/tiny top to root while keeping the water from evaporating much, while keeping the top in the “correct” position the whole time. Just wanted to share in case it inspires some new thoughts or feedback! I consider myself to be a “terrible” clone whisperer and was excited to see these chunky roots forming after callusing over.
