If you are using artificial lights I would switch them off totally now and remove any panels or covering that you have if they are growing inside a growing cabinet like mine would be. This is of course the shortest month, within a week we shall be in March, so give the plants plenty of air, open the roof lights wide on nice sunny days. In other words, start to gently harden the plants off for planting out in their beds, under covers, around mid April.
