High Expansion Foam Generator?

[loriheath]

Hello,

I am the Project Coordinator for a non-profit organization based in St. John's, Newfoundland.

I am seeking used (low cost or donated) high expansion foam generators to be used in a special type of greenhouse which can grow food in winter months.

Does anyone happen to know where I could find one or more of these?

Please email loriheathmail(at)gmail.com if you have any leads.

Thanks very much!

All the best,
Lori Heath
