That is what i use. I haven't had a problem with them being to stemy but then again I don't usually start them till the end of March early April. I want to start them extra early to see if I can get them nice come spring. Last year as soon as they started to sprout out about an inch I rotated them. I usually did it every other day. I rotated them every which way that I could. I turn them around, move them to different levels. This year I think that I'm going to try to put a fan on them to help them get stronger. I don't mind trying new things with the seeds. They are cheaper then the already grown plants.I have one of those little 4 shelf greenhouses, itching to pull it out again. Hubby and I were discussing getting grow lights, since we start our own seeds. But reaching to the window for light makes them too leggy and they usually break in the wind as soon as transplanted. Got plenty of leftover seeds, so going to put the seed money to growing supplies instead. Anyone have recommendations? We do have some fluorescent light fixtures in the garage that will be replaced, can we use those with the HO T5 or T8 bulbs? I seen CM has grow lights on sale, with a 20% sale next Friday, but want to keep costs down.
