Im going back to using his wires this year. I did it one year, decided they were to expensive and marking on blinds would do the trick. Well, as it stands, between the squirrels digging up the markers and permanent markers being not so permanent, the only few seedlings I even know what are anymore are the ones that I dig up and the wires are right there burried with them. They dont fade, and the squirrels dont throw them out of the pots. I just come in and match them with the list from years past. Even if you buy the ones with alot of colors, you do have to mix two wires, unless you only have a few seedlings.
I also have bought his viles, I finally stopped saving pollen, I never used it. There are always enough flowers to choose from, not to have to mess with the pollen. I know once Larry Grace gave a talk and said he saves his pollen in match boxes.
I have used pollen that has sat on a paper bplate for a day or two and it works just fine. Like you siad above, oce the temp gets to high, nothing works, altho if the plants are in pots, you can bring the pots inside and that works like a charm. I think it was Phil Reily who shared that trick.
