I bought this for starting my seedlings this spring. It easily hold 12 flats on the shelves (BTW, turn them upside down and fasten to the shelf support, keeps the flats on them in wind). There's plenty of floor space to move or store items and for my purposes it's very sturdy. We are still having outside temps in the low thirty's and high twenties, but it is super easy to heat with a small, cheap ceramic heater
No regrets buying!
