Desperately after some information, I can’t afford a proper greenhouse so I’ve been looking at the walk in ones that have that have powder coated steel frame with a waterproof PE protector cover, are they ok for sowing seeds in now and potting up my dahlias? I don’t know whether there frost free or suitable for using now? I’ve started some sweet peas, leeks, onions and tomatoes already germinated in the house but I now have far too many to pot on and keep in the house so was hoping to pot them on out there as I need to sow a lot more inside. Grateful for any help it’s my first time with seeds so want to get most of it right if possible!
