Q.Hardning of plants
I live in Ontario and grow most of my plants from seed under lights so they all need hardning off and to get them into the garden as soon possible is it possible to take advantage of the odd warmer days that come at this time of the year and make it a cumulative in other words it may two days now and another day in a day or two until they reach the full four or five days that I usually alllow.

Yes, I've hardened off plants in the way you describe and it's worked for me in the past. The "cumulative" method seems to work.
