Cardboard Cloner 2.0 beta released
I came up with an upgrade for the above tek. I think it will work well and am just trying for the first time.
The goal of this new version is to make a "fast turnover clone cake" by using a variation on the methods above. It is hoped that this will work particularly with cubensis.
This is a brief overview that will be expanded on and merged with the tek if all goes well.
List of things needed:
1/2 pint jars
Card board discs (see top post)
Clone material
BRF (brown rice flour)
Vermiculite
Breathable lid
PC or steamer
Procedures:
Unlike the last version the cardboard goes last here. First goes a touch of verm to catch any extra moisture , then BRF/V mix. On top goes 2 double sets of moistened corregated cardboard. The top inch is left unfilled.

Wipe the top inch with paper towel to get any remnant brf off the glass. Insert the two soaked double layers of cardboard and gently tamp down.PC for approx 60 mins at 15 psi and cool.
In glovebox open jar lid and pry up one double layer of cardboard and place the clone material you "scraped" from the inner stalk in between. Replace top cardboard disc , lightly tamp and replace lid.

Now there is a small 1/2 inch gap between the top cardboard and the top of the jar for a small bit of air.

Soon the clone chunk will grow into the cardboard and then at its earliest convience into the BRF. Once colonized you birth the cakes and you have an instant crop of clones , or you spawn those cakes on to bulk projects.
There can also be a variation on this tek where you use wbs in this same manner of food first , cardboard on top.
The tek can be done either way , but this way is very practical for birthing clone cakes in a short time.
Any comments appreciated. I'll keep you posted with results good or bad. As always please try this at home and co-create this tek with me.
cheers
