Aren’t all gardeners? During some very bleak years with no prospect of gardening at all, I still bought seeds because they were (to me) hope of better times. The weeds, weather and other woes are all still to come, with seeds one is buying little packets of promise.
I am seriously considering removing the bed from the spare room (it has been occupied for two nights in the year we have been here) along with the carpet, adding racking and some sunblasters, plumbing a sink from the bathroom next door and turning it into an indoor grow-room. It’s the way I use it most (apart from drying laundry, and I don’t feel the two are incompatible. After all, one does it in the actual garden)
(I have two boxes and a drawer for overspill. It’s normal and healthy, I tell you!)
It would be cheaper than the lean-to greenhouse I’m saving up for, and more reversible should I move or fail to rediscover my green fingers)
