Basically I'm just some crazy kid who likes plants but doesn't know much about growing them. What I want to do is find some small little plant, or a seed. And plant it in this, what do I need? Can I just use dirt from outside? Do I need specific soil or some shit? Help plz
from seeds, plants take a while depending on the breed to actually shoot and become strong. In the meantime they are incredibly weak (some anyway) and they generally need alot of effort for no long term visual feedback.
Now cuttings, that shit is cash. learn how to maintain cuttings from older plants and skip the shoot phase of seedlings.
I would advise some better containers with holes in the bottom for better chance of not overwatering a young plant. Though I see the appeal of the jar itself.
I dont have the conditions where I live, but I would love to grow a redwood from a seed that I could find inside one of its pinecones. Those things require strange tempature conditions to germinate however, but they grow so fast.... imagine showing your grandchildren some 60 ft tall redwood and saying "I planted that when it was just a pinecone"
Seriously op i shit you not i was in your exact position like 2-3 months ago.
Id just seen the movie the martian, id allways wanted to grow things and i had this moment where i was like "if matt damon can do it on mars with just what he had, surely i can do it on earth".
So i scooped out several seeds from a butternut squash while i was preparing it to cook and put them to one side, i found a small plastic container with a screw on lid, similar to yours in size, i wend and dug up some dirt from outside, put it in the container, pressed the seeds in about an inch, i planted 3 of them btw, watered it well then screwed the lid on and left it on a windowsill, id open it for like 10-15 mins a day and give it a splash of water when it was looking a little dry, and you know what...
After about a week, They sprouted, they grew, overnight they went from little "hey there might be something going on" to alive, a shoot with two round leaves...it was such a happy feeling.
Ive still got those sprouts, theyve survived 2 serious pot size upgrades and now live outside in partial sun, theyre growing well and are about due for another pot upsize.
Pic related is them, maybe a week after they sprouted, they were droopy so i supported them with some metal skewers and some cotton tied gently around the stalks in loops.
So op, in summary, dirt from your backyard is fine, that container is fine, all you need is a seed to plant and to water it each day.
I'm in the same boat as you OP.
What I did was just get an empty gatorade bottle, cut the top part off so it was just an open container, fill it with soil from my backyard, and planted a pea in it.
