Assuming it's a clone, it could be about a month old maybe 6 weeks. If it's a seedling, maybe 2 months.
Plenty of time to make it awesome, unless its autoflower. But if it was, most of them would have started by now. You dont want autoflower, restricts many things.
I would start by making an environment for it. It can be cheap and DIY or cost a little bit, and be made for you.
Basically you need an enclosed reflective space, to make your light more efficient and to keep the plant safe from all external influences. It can be as simple as 1x2 wood frame and panda poly film. Less than 10$ to make this tent.
Or you can just buy a 2x2x4 tent off Amazon for 50$
Then you need light. In a small tent, I would go with screw in LED bulbs. Dollar store sells 100w eq led bulbs for 4$ canadian. I use 7 in my DIY micro tent. The 7 to 1 bulb splitter is like $8 on Amazon or ebay or wherever.
And then airflow. I use a 200cfm
vivosun duct fan because I want to be able to filter the smell. But if you dont care, a $15 or $20 100cfm inline duct fan is enough. I've heard of people using bathroom fans too. You will probably want a small computer fan or usb fan to blow air around over your canopy too. I got mine from walmart for $5
If you feel like spending, a 20$ grow tent fan from Amazon would be good.
That's about it. From there it's just scheduled watering and nutrients. And a bit of light timing.
