I have not grown on red plastic yet, although I plan to this year. Last summer I had a long conversation with a local farmer who grows all his tomatoes on red plastic. Says he gets a 15-20% increase in yield over black plastic or irt plastic. Somewhere I read a study on the use of red plastic and their findings were similar to this farmers'. This farmer has the prettiest field I have ever seen. He grows two acres of tomatoes. All on red plastic with white clover growing inbetween the rows (he cuts it with a riding mower). You gave me a great idea for an experiment, however. This year I will try a few of my tomato seedlings in red plastic cups rather than the usual six packs or 3 1/2 in pots. Will be interesting to see if it makes any difference. Bill McKay in E. Mass >We have a nursery specializing in perennials, mostly daylilies and >belong to a daylily mailing list.
