Hey guys, I'm new here.
I come from a country that cannabis isn't exactly legal. I've been medicating for a very long time.
I prefer cannabis over the pills I'm prescribed. Which cost an arm and a leg in comparison.
The problem is always the availability here.

So I've decided to try and grow my own. I've never been successful getting past tiny sprout.

I'm growing in the attic of my house. Grow lights and outdoor aren't really an option for my situation.
I have placed the medium and sproutlings by the window with a plastic over the pot. I have some vermicast coming in the mail.

I live in a tropical place with plenty of humidity, currently at 56% with no drastic changes.
The spot i had placed the pot is by the window where it can get plenty of mid day sunlight.

I'm trying to research good tips and food for my soon to be plants. All I've been seeing are fertilizers and food specifically for cannabis. Unfortunately I have no acces to such products. I was wondering if anyone can recommend generic store kinds.

I'd appreciate any advice to help me get to the harvest stage of my grow.
