Growing a plant under one lamp?

I have a plant outside and it's almost done flowering so I can only assume whatever else I put out during the next few months is automatically gonna flower.

So it looks like until next year the only option I have is to grow indoors right?

Well I really want to start my next grows and I don't really want to invest a lot of money into lights so maybe $20 worth of lamps which I'm assuming will get me around 2 decent ones.

Can I leave a plant in the corner of my room with one lamp above it and let it grow very slowly or will that somehow affect it's health? Also wouldn't it start to lose nutrients and be more expensive of I kept it like that until next year?

What's the best option during this time of year?

Well if u leave it in your room for 5 or 6 months that thing is gonna be huge if u know what you are doing. Secondly what kind of lamp u gonna buy with 20 bucks I'm guessing cfls

Good luck with that budget. I suggest giving up until next year. If you are having to ask I sense your keeping a mother plant will not be successful.

Look at clf growers.
