My Greenhouse Project

Hi everyone. Sorry for the panic posts on some of your guys posts. I’m really new to rocket mass heater and I think I’m gonna do more research before building one in my greenhouse. Here are my challenges, Im in Wisconsin zone 5b, I have a 100 feet by 30 feet hoop house and I’m going to double layer with plastic. My first question, is it possible to have an underground bench about 110 feet long with a bypass and possibly a heated gas going into the pipe to prime for draft? What type of rocket mass heater should I get? I would like to build a chamber so I can fire my ceramic. I still have more questions but maybe we can keep a thread going. Thanks so much for all you veterans out there willing to help.

I don't think a rocket stove of any type is going to work for firing. The temperature swings to rapidly, would likely cause major cracking and possibly violent deconstruction with shrapnel. AKA steam exploding ceramic  

Hey Von!
Here is a link to some rocket kiln information:

Here is a link concerning your long bench idea:

If I were in your position, I would try building a short, temporary, above ground bench powered by a   j tube style rocket.

Truly so helpful!!  Thankyou sooo much!
