I got a smaller walk in greenhouse (the kind that's easy to set up and take down but can blow away if you're not careful). I'm planning to use it inside to start seeds and then outside for maybe a month to harden off seedlings. I did that last year and it worked great. The new greenhouse can fit at least twice as many plants, plus I still have my old smaller one.
I also got 1 gallon fabric pots for my lettuce and a whole bunch of plant tags so I can label my seedlings better this year.
Now to wait until sometime in February before I start seeds (and maybe get a few grow lights to be safe).
