who asked about wsing in a greenhouse?
I did all my winter sowing in a small greenhouse this year, it was unheated until April,1st. I picked up a $7 heater at walmart and set it at 65, I turn it off during the day. I am amazed at how well every thing is doing. I have hollyhocks that are 8/10 inches tall already.
I planted lots of alyssum and some is budding, ready to bloom.
