Hey Ganjalf,
haha that’s a funny name! Also, cool that you’re growing H24 - is it from Pachamama? I’m running the same Strain if it is!
Anyways, if you’re at home most of the day you can go directly in the ground - just check that the little lady doesn’t ever go dry. You could also construct a little shade cloth structure to help it in its early day.
otherwise there is another option, neat little trick I learnt when I started autoflowering plants - got it off the internet. You basically get two small pots, one will be the inner pot and the other will be the outer pot.
With th the inner pot you want to cut big lines down the sides of the pot, in a strip. Cut as many as you can. About 2-4 cm wide, and from the top to the bottom. Then also cut out many large circles from the bottom. You put this inner pot inside the other and fill it with your medium and pop your seed in to grow.
Once its grown out for about bout two weeks you then simply remove this inner pot, and you’ll see the roots coming out the slits you cut. You just plant the inner pot(with your pot in it) directly in the ground! So it’s like transplantin except you don’t disturb the roots much! Just be careful not to let the plant stay in there too long before burying the pot!
just another tip, get yourself some neem oil for preventative spray on your foliage o protect against grasshoppers etc.... also get some copper wire and make many loops of it loosely around the stalk of your plant (careful not to restrict it, you may have to adjust it) this helps with slugs!
Your medium looks good! Is it light and airy? If not, go get some perlite and dig out the hole where your plant will be, mix in about 30-50% perlite and put it back. Helps airate the soil, autos love air rated soil.
lastly, if you can get your hands on ‘mycoroot’ get yourself some and put it in your inner pot where your roots will grow - it really helps root growth!
Ill be following yor grow! Excited to see how it pans out! Good luck man 18092018.
