tomato starting/temperature question
I realize that tomatoes grow best at temps over about 60. However, I have an idea/question...
If I start tomatoes for spring planting in late February or so, in a greenhouse or room where the ambient temps run on the cool side for tomatoes (50s/60s) would they do OK if the SOIL is heated to warmer temps even if the air is coolish?
In other words, would tomatoes with their roots heated to about 80 or so w/heating cables or mats do reasonably well at cooler air temps due to the soil being warmer...?
