Hi there

looking for some advice if poss about my spinich, i planted as plugs in seed tray initially after buying, i still have them in my 3 tier mini greenhouse but i wondered is it too early to put them into pots or grow bags in the garden?

in my inexperience they are just sitting there waiting to be moved onto bigger and better things and not sure when to put them out?

Please could you give this very novice novice some guidlines for the spinich
thank you
