@ResinaGenetics Hi there! In a few words : good idea for photosynthesis strain, bad idea for autoflowers. Starting with small containers such as 0.5L AirPots is great for regular photosynthesis strains, since it will help to prevent overwatering and the roots are supposed to explode once you'll transplant them into bigger containers. It's also a good way to ensure that your roots are healthy when you repot. However remember that repotting/transplanting is a delicate operation that can stress/hurt the plant for weeks if done wrong. Putting it immediately in a 18L pot is the safer option for an optimal growth if you manage not to overwater it. I'll be around, keep us up-to-date and good luck with these babies!
