Hello, I bought 2 new autoflowers today. How should I start now? Should I first put the seeds in the grow mix soil and how much water should I give? I’m doing everything old school without a grow box.

Welcome to our community! Here you can get all the information and advice you need from experienced growers. You can also exchange ideas with other growers and even participate in a competition.
Thanks a lot, Magic.
When can I put them in the soil?
With autoflowers, it’s usually best to plant the seed directly into its final pot once it has germinated and the taproot is visible (typically 0.5-1 cm / ¼-½ inch long).
Autoflowers have a short vegetative stage, so minimizing transplant stress helps them reach their full potential.
Plant it about 1 - 2 cm (½ inch) deep with the taproot pointing down, keep the medium lightly moist (not soaked), and let the seedling do the rest. ![]()
If you need information about how to germinate it, I always suggest GWJ Growing Guides: How to germinate Cannabis seeds: a guide for beginners
Super thanks @Eli
Hi @Dragon, if I understand you correctly, you are growing them outdoors. Let the seed germinate; it usually works well in a paper towel. Place the whole thing in a warm and dark place. It shouldn’t be too warm, or you’ll cook it. If all goes well, it will sprout in 1-2 days. Once the taproot is out, about 1 cm, plant it directly into the final pot. Then water it well, but not too much, and then put a dome over it (plastic cup/bottle) whatever you have at hand. It’s best to fix it with toothpicks or similar so it doesn’t blow away outdoors. With the heat we’re having right now, I would rather place it in the shade until it has grown a bit, and definitely avoid the midday sun at first. When the leaves touch the cup, you can remove it; by then, the little one has enough roots to absorb its water through them; before that, it gets it from the air. It’s been a few years since I cultivated autos and outdoors, but that’s how I always had a good start with the little ones.
Thanks @herr_gruen
No, I do all of this indoors, because our neighbors have too much of a mouth
you know what I mean, and currently here in South Tyrol, Italy, it’s rather humid and wet with thunderstorms.
OK, that’s good, like spring
. Seedlings need about 75% humidity, so I would still put the dome over them at the beginning. But if it’s not too hot, they can also be in the sun. I would only shade them a bit from the midday sun until they are a bit stronger.
Thanks @herr_gruen. Well, there’s no sun
at the moment. But thanks, good to know. ![]()

To avoid overwatering the soil from the start.
I would moisten it with a maximum of 100 ml per liter of soil.
Let it soak in for half
@Pflanzenpaul many thanks for the info![]()

happy growing back
A good way to figure out how much you should water is by the weight of the pot or the 10% metric. Water with 10% of the pot size, if you have a 10 gallon pot water with 3/4-1 gallon of water. With a 1 gallon pot water with 1/3 liter.
