Hoop Building Tomato temperature Questions
Comments (10)Well we made it through last night. It wasn't as cold as earlier predicted. It was 35 on Thursday night. I did cover everything up and turned on my additional heat. I went out this morning a 6:00 and it was 44 degrees in the building. I was kind of shocked. We had a strong 30-40 mph winds all night long. Today it is only suppose to get to 45 for a high. I left everything covered and closed up. I am worried about this weekend. I have seen 3 different forecast. One has us in the 27-30 range for lows and 50's for highs and a chance of snow. Another one has us in 34-37 for lows and 55 for highs. I guess I am going to plan for the lowest and hope for the highest! Tom- I have used milk jugs before, but I have another system that works the same. I use 4 inch pvc drain pipe cut into 6-8 inch lengths. I plant the plants and then put them around them. If there is a chance of cold, I cut the bottom off of 2 liter bottles and slip them over the PVC pipe. It is like a mini greenhouse. One year I planted out and the next week we had one 32-34 degree night and I spend 2 hours cutting and slipping close to a hundred bottles over pipes. It did get that cold during the night, and everything survived....See MoreLowest Temperature Tomato Plants Can Withstand In Greenhouse
Comments (26)Timmy, I'm surprised at that kerosene heater recommendation. Unvented kerosene heaters will cause tissue damage to tomatoes and many other plants. Unvented propane can even be risky. The only problem I ever had with wood is when my wood pile was stacked too close to the stove and caught fire one night. KK, that being said, I would have a foolproof heat system for the investment you are making. Furthermore, you want inside circulation fans (at least 2 on each side, each side moving air in opposite directions). My experience is that when you lose plants on a marginal night, those lost are plants in a corner or end. The same occurs when you have a framed cover within the structure. Never assume that when the weatherman forcasts a low of 32*F that it won't drop to 22*F. Either way they won't lose their job. As a large investment grower you need to insure survivability of the crop by preparing for the worst set of conditions....See MoreHoop Building Tomato temperature Questions

Comments (14)I gotta agree with Dave.. in general, I follow his plan of pick while the blushing is good, and after that first morning I look out the window with coffee in hand and see the white coating (for me its the long patch up the easement drive where the best dew and frost collects), that is the good frost around here.. Then at that point I strip down the warm plants.. and that depends on the plant. I have containers I will bring inside. Some plants that are heavily laden with fruit, then those get pulled out, cleaned up of dying foliage, and hung upside down in my solarium for a couple extra weeks of growing/storing/harvest.. not sure what one calls the process of hanging plants for other ripening. Anywho. Other plants that just have some greens and such on them- at first good frost they get stripped of fruit, plant cut up and placed into cartons for slow ripening.. then the plants tossed into the compost bin. I tend to do this process in stages.. like right now nights are starting to get down into the 50's, so the container plants have been brought in to acclimate to their fall inside season. When the forecast calls to dip down below 55, but above 42, I will pull plants for hanging up. When that first good frost hits, I will pull the whole shebang on whatever warm season is still out there....See Moredaninthedirt (USDA 9a, HZ9, CentTX, Sunset z30, Cfa)
