Yeah, my exact thoughts too! We do have a deck off the kitchen. Fairly large one then a smaller one next to it off the porch room. But for $150, I don't think it's worth it. I could build a massive garden bed.
And yeah exactly what I thought! But they claimed they had tomatoes growing. Of course, they never said how big their yield wasmime struggled even in a pot.
Definitely don't have one of those but I wish!
You could try making straw bale gardens. I did just a small one with the kids and it worked really well. Cheap and easy. Definitely want to do it again when we are settled somewhere.
