I moved a tray of seedlings off the windowsill for the third time in one afternoon, chasing a patch of sun that had already slid past the kitchen table by the time I got there, and admitted to myself that I was not going to win this particular fight with my own house.
What I actually have to work with
My rowhouse has three windows that get meaningful light in winter, and none of them get it for very long. The kitchen window faces roughly the right direction but is partly shaded by next door’s wall for a chunk of the afternoon. The front room gets a decent stretch of morning light and then nothing. The back bedroom window is small and mostly wasted on a plant unless it’s something that barely needs light at all. That’s the whole inventory. No conservatory, no glassed in porch, nothing built for growing.
I spent my first winter here assuming I could compensate for that with effort, moving trays around the house to chase the sun through the day like I was doing this morning. It helps a little. It does not fix a fundamental shortage of light.
Why I can’t just build my way out of it
The obvious next step, and the one I looked into properly in my second year, is a proper grow light setup, maybe a small dedicated shelf unit near one of the better windows. I priced it out, read up on it, and then hit the actual limit, which isn’t light at all. It’s my tenancy agreement.
My landlord doesn’t allow permanent structural changes of any kind. No shelving fixed into a wall, no anything drilled, screwed, or otherwise attached in a way that isn’t easily removed with nothing to show for it afterward. A proper grow shelf, wired in, bracketed to a wall, is exactly the kind of thing that’s off limits for me here, not because it wouldn’t be effective but because it isn’t undoable. So the version I actually run is a freestanding light on a cheap stand that sits in the corner of the front room, plugged into a regular socket, moved out of the way when I need the floor space back. It’s less efficient than something fixed and purpose built. It’s also the only version I’m allowed to have, and I’ve stopped resenting that limit and just designed around it.
What I’ve given up trying to grow indoors
I gave up on starting anything that needs a long stretch of strong light early in the season. I tried a batch of seedlings that wanted more hours of good light than my setup could give them, and what I got was pale, stretched, leggy growth reaching for a light source that wasn’t strong enough or close enough for long enough. I misjudged how much of a gap there was between what my little light and windowsill combination could provide and what those particular seedlings actually needed. That was a wasted tray and a couple of wasted weeks, and it taught me to be honest about the ceiling on what I can start indoors rather than optimistic about it.
Now I keep my indoor starts to things that tolerate a slower, dimmer stretch before they go outside, and I’ve accepted that some things simply do better started later, outdoors, once conditions catch up, rather than rushed indoors under a light that isn’t quite strong enough.
The windowsill herbs that actually work
Where I’ve had real, repeatable success is smaller and less ambitious than I originally wanted. A few herb pots on the kitchen windowsill, moved a little through the day, do reasonably well through winter, not lush, but alive and usable for the kitchen, which is honestly the whole point. They don’t need the kind of sustained strong light that seedlings destined for the garden need. They just need to not be forgotten and not be left somewhere freezing, which the windowsill, close to the radiator, manages fine.
What I’d tell someone in the same situation
If you’re renting and your landlord has similar rules, and a lot of rental agreements do, I’d say don’t spend energy trying to recreate a proper grow room setup through sheer improvisation. It won’t match a fixed, purpose built version, and chasing that comparison just leads to disappointment. Work out what your actual light is, honestly, not hopefully, figure out what’s freestanding and undoable that gets you close, and then pick what you grow indoors based on that ceiling rather than on what you’d like to be able to grow.
My own conditions, this house, these three windows, this stretch of afternoon shade from next door’s wall, aren’t going to match anyone else’s rental, so I go by what I’ve actually watched happen here over five winters rather than a general rule about how much light a windowsill supposedly gets.
Where I’ve landed on it
These days my indoor winter growing is modest on purpose. A stand light I can unplug and carry into a cupboard when I need the corner back. A few pots of herbs that don’t ask for more than the kitchen window can give. Nothing screwed to a wall, nothing that would leave a mark if I moved out tomorrow. It’s not the indoor setup I imagined in my first winter here, but it’s the one that actually fits the house I live in, and five years in, that fit matters more to me than the setup I originally wanted.
