Right now I have no Winter setups

Fukushu kumquat grafted to flying dragon is 1 year 51 weeks old since bud swell.

Installed 8 sheet of glass 76inches by 46 inches.

Installed another 8 sheet 34inches by 76inches.

  Because I have no trees right now

  Because I have no trees right now so I have no Winter set ups

My trees won't be going inside for another month or so.

We are disappearing for 3 weeks mid October. There is a 50% chance of fruit destroying frost by November 7 They have to come in 3 weeks from now.

East window 4 layers of glass.

We are a month early with this dam cold!! Time to get ready sooner than later. Thanks to hurricane Ian, sitting of the east coast. No rain in a drought stricken area, just stinking cold winds.

I am glad a hurricane won't rip your set up apart Steve. Lucky us.

More glass added

My greenhouse temperature gage shows no freezing temperatures yet.

@Lemon Lime Orange Zone 6a Do you provide any light for your trees? How cold do they get?

100 percent artificial light with Gavita Pro RD2400e LED. Air temp on left. Root temp on right.

New flush, new bloom and larger fruit since bringing indoors. Gavita light has exceeded my expectations. Would like to see roots warmer but it has been a challenge with an 80 lbs clay pot. Because of cold roots transpiration of nutrients has been slower than it would normally outdoors with this light level. Have used the following as foliar spray or drench; Jacks, Southern AG nutritional supplement, Southern AG Iron and Sulphur, Grow Scripts bloom time and maintenance forumulas. Tree has responded much better to foliar spray, and drenches. I know I have the right minerals in the pot but they are not available fast enough so have had to off label extra feedings of foliar or drench to keep up.

 I have no trees to right now  to even make a Winter set up

 Maybe the roots got warm enough . you said it was hard to do but remember that doesn't mean that they don't get heated enough  to help that flush to develop the flush growth
