Welcome to the community 
You’ve come to the right place as a beginner, there are a lot of smart and good growers here and people are very helpful.
Your seedling setup already looks very good, you’re providing humidity as well as fresh air. If it’s warm enough now, that would be great
I am an indoor grower myself and can only help you to a limited extent. But there are a lot of outdoor geniuses here who will surely get in touch.
What strain do you have there?
Best regards and here’s to a good grow 
Any advice is good bro, whatever you know could also help me
So you don’t really need expensive equipment for growing outdoors. It would be interesting to hear what your plan is. You’re currently growing in a pot, I think, right? Do you want to put it in the garden soil outside then, or leave it in a pot on the balcony?
Do you have a feminized or auto plant?
If you just want to put it outside in the pot/container and invest as little as possible, an All-Mix soil is recommended. That way, your plant would be supplied with nutrients for its entire lifespan and you’d only have to learn when and how to water with an adjusted pH level.
Under this plan, the investment would be the All-Mix soil, and a meter to measure the pH level of your watering water.

Cheap and easy. Get some Gaia Green 444 and 284 off amazon, like powder not the pellets, then some Eart Worm Castings or EWC for short to help the microbes. And then I personally use 70/30 coco/perlite from Foxfarms but I’ve been seeing great growth outside with just outdoor soil plus the nutrients I said above and they are so massive I had to top it because it was outgrowing the cover crop! In all honestly I spent overall like I think $120, but only needed like $30-$50 worth of it for this year so 100% one of the cheapest and safest ways to grow
Finally the outdoor growers are showing up 
awesome
I don’t grow outdoors these days but I did for a long time. When I was working outside my method was very simple, direct planting in the ground, good quality organic feeds, mine was just from the compost pile but the Gaia greens that @Yvngstonie suggested or something similar would be great and a sheet of clear plastic for a roof to protect from rain. If you keep things simple it can be very rewarding
