Some of the seedlings I have planted from seed are tall and very spindly. Our last frost date is May 16. I read in other questions that this problem may be due to too much heat and not enough light. They are under grow lights, it must be too warm[73 average]. Is it too late in the season to start over or will they staighten up outside? My seeds are cosmos that are having the problem and morning glories.

Although that is a bit warm for seedlings, these particular plants tend to be leggy. Cosmos are naturally very tall and leggy, so they may be normal. Morning glories also stretch to climb very quickly, so they may also be normal. Both of these plants are usually planted outside where they are supposed to grow because of these tendencies, as well as their quick growth rates. This season is so warm that you may not need to wait for the average frost date before setting them outside. (It is just an average.)
