propagator

 Mart has summed it up nicely. For me the main value of warmth in propagating it to help germination and the first stage of seedling growth, especially in early spring. I give many seeds three or four weeks gentle warmth, then give new sowings a turn and so forth. A windowsill is warm enough for this but long stem growth means you can’t keep plants there for too long. Fruiting vegetables are mostly the ones to benefit from steady warmth – tomato, melon etc, also basil.
