My son Ashton will make all his tet crosses in the morning and by the time he gets them tagged and takes a break it will be noon and in the 90's when he starts doing dip crosses. We will have 10 dip pods to every tet pod. I set pods on diploids anytime of day or night. I work lots of hours and often have to leave home in the dark of the morning. I come home even with temps in the high 90's and the only key to setting seeds is finding or having good pollen. If I put a bloom in the fridge or have something I want to use growing in partial shade, I have used the pollen at 5 pm and 98 degrees and set seeds regularly. It is as hot or even hotter here that at Carpenters and I know I have set seed at 7pm and later. I don't really try this on Tets as they are difficult at 9am or 10am on warm days.
