As I’ve grown these in a small cell then I simply pop this out from the underside of the tray and plant the entire seedling with the basis ball intact.

When rising vegetation to be used in my greenhouse, I at all times use a brand new clean plant pot. I do that as a result of I don’t want the potential for introducing illness from an old plant pot into the compost surrounding the basis. I’ll reuse the pots once more, however just for vegetation I shall be rising exterior. As I solely grow about 20 vegetation in my greenhouse, (tomatoes, chillies and cucumbers), it’s not costly to purchase new pots for this small variety of vegetation and it’s price it for the peace of thoughts in attempting to maintain my greenhouse illness free.
After getting potted the seedling up you could let it develop and grow on and through this era the temperature could be decrease. My vegetation are presently in my greenhouse and the temperature in there may be now 34F. I do have my vegetation in an electric propagator and the soil temperature in that is 46F, however I might simply as simply grow them on, on a windowsill in my house. I simply suppose the light is best within the greenhouse.
