Great tek!!! I will definatly put this knowledge to use in the near future, however I have a question. I recently constructed a shotgun terrarium for BRF cakes. My plan is to get a system going that works, harvest some fruit and then move onto bigger and better things like casings. Now from what I understand a shotgun terrarium built correctly and with a layer of perlite at the bottom creates100% humidity, now when dealing with casings as you also stated above you want your humidity to be somewhere between 82% and 92%. So my question to you is what can I do to modify my shotgun terrarium so that it is between 82% and 92% humidity? or if you know a better type of chamber or technique for casings that supports the proper humidity, what would that be?

peat moss and vermiculite makes a perfect casing! PH buffed of course

This tek is quite good.  I recomended it. However...

When I prepared casing material with the above recipe, I squeezed out 5 1/2 cups of water to achieve field capacity.  I have adjusted my notes and shell use maybe 10 cups of water next time. 

Your mileage may vary.  Keep good notes and you'll come to what works best for you.

I plan on using this method for my first attempt!  

I also had excellent success using this method. Wonderful Tek and much appreciated.

I have had great success using only Perlite underneath the first layer of colonized substrate. I put about an inch of perlite soaked with Hydrogen Peroxide in the bottom of my casing.  The top layer is all vermiculite (about 3/4 of an inch) and I've had great success!

Thanks for the comments
