Not a skilled plant-owner here.
A friend got some buds with seeds on them, and I'm trying to grow some. Tried two first, but both died right after sprouting. Now there's this other one in the pic, planted last week and sprouted yesterday. Theres three other seeds next to it, too. I think they were either orange haze or godzilla cookies, if that matters.
It's hot where I live, and there's a good range of sunlight I can expose it to, from direct, harsh sunlight all day to partial, indirect sunlight, depending on where I place it in the apartment. I also got a cheap yellow+blue+red growlight that I can adjust the intensity of and set timers.
Other stuff I have lying around: a rooting agent, bokashi, and a substrate made of spaghnum, perlite and rice hulls.
What should I know about watering, light schedules, wind, temperature, budding care etc?
E: I should add, I'm not interested in a super-optimized,industrial scale high-yield techniques, this is just for hobby
When they're out of the juvenile phase and are about half the size you'd like them to be at full growth. You can also do very simple things like topping the plant when they've reached about 6 nodes so they produce two colas instead of one. Imo I'd recommend watching some videos / reading some guides, I'm an amateur grower at best and have just picked up tips from people over the years.
