I have this two plants that I thought were both prone to temperature banding. They are planted next to each other. Gespacho has done some nice banding while Bob and Grace did nothing. When I planted B & G a couple of months ago, the last green bands were in the centre of the cup. So it obviously did not produce any green since I have got it. Our night temps, for the past two months is mostly 12 degrees and goes a lot down to 8 but then our day time temps do not rise much higher than 15. We do get the warmer days and nights in between. Is there not enough diffirence between day and night or is Bob and Grace just a much more difficult one to give this bands? Or is it not temp bands in ts case?
