help needed for tomato plant
I have what i'm pretty sure is a tomato plant, that grew from a seed in a washing up scourer, so I've put it in a pot, complete with the scourer, which i pinned down to the soil so the roots wouldn't have any air gaps. it seems to be doing pretty well in my south west facing first floor Yorkshire window, but I know this is completely the wrong time of year, so it's going to need help.
I'm not fussed about fruit, though some would be nice, but I'd just like it to survive.
What should I do now? I've bought a grow lamp from Amazon, but the instructions are so minimal, I don't really know what to do with it.
