Plastic over PVC frame with space heaters plugged into Thermo cube. I'll try to send pic. Last attempt failed.

To order from Mckenzie you have to call or email him anyway. He will email you back and let you know if he has something. I've ordered from him and he sends good trees in pots.

I even lost my PT hybrids this year with lows over night two or three nights at zero. They were ) ft tall and packed in leaves and surrounded by buckets of water and covered by frost cloth and had plastic wind break frames built around them. The only things that survived here in my 7B/a local was the grapefruits and sats that were covered by plastic and had space heaters with fans blowing in them. The ones with plastic and heat lamps died completely. The plastic even with garbage can full of water in it holds heat for no time at all unless you pump electic heat in it when temps in twenties over night. I had to cover and uncover all protected trees daily and sometimes twice a day to prevent breaking dormancy during day. Hard to do all that when you work 36 miles away from home. I'd say have a few trees you want to work hard for. Don't over extend yourself. I used Thermo cube to turn on heaters automatically when temps got near freezing and they turn off when gets to 50 degrees. I got them at tractor supply. Good luck.
