Ths subject seems to be a constant one for me. No matter how many lights I buy, how much sunlight my plants get, what direction the windows face that they grow in, etc., I still have a handful of people out there saying my tomato seedlings are very leggy. In my experience, the past few years, this windowsill method has had some great results. The tomato seedlings, out of peat pellets or whatever, start out quite leggy, then as they get potted up into the 16 oz plastic cups, they become less so & start to grow outwards more than upwards. Then, finally, when I put them in their final homes of container outdoors & bury them a few inches or so deeper than before, they grow fine & produce fine. So, I guess I don't see what the big deal is.
Please let me know what negative effects you have had with supposed "leggy" tomato plants(and other veggies like peppers, herbs, etc.). Like I said, my plants do perfectly fine, so I don't see what the big deal is. =) Enlighten me...
