i'm growing outdoors, can my seedlings take full sunlight immediately or will they get burned?

they sprouted like 3 days ago, but one looks a like it's too tallHow big of a seedling r we talking here? I’d say if it has any real leaves on it it should b ok
i don't grow indoors.Hey fatbuds, It’s called hardening off. This is the process for transferring an indoors plant to an outdoors environment. Maybe check over on the outdoor growers section here and study up. Most take a week or so to slowly expose the new seedling to outdoors. Start out in shade not full sun etc.
Too tall? Stretching can be a sign your not giving enough light.
When they sprout in the wild many of them are going to be getting full sun for 8 or more hours.i'm growing outdoors, can my seedlings take full sunlight immediately or will they get burned?
the issue with this statement is a few thingsWhen they sprout in the wild many of them are going to be getting full sun for 8 or more hours.
If you put the seeds in small containers yourself and the containers were not in full sun then you could consider moving them into full sun over a few days. Otherwise if they were in full sun from the git-go they should be able to handle it.
If they were planted directly in the ground, like in a garden, and not in a pot the new seedling will handle whatever light it can get or is exposed to.
Have fun with the outdoor grow.
yeah we get up to 40c in the shade, and also they pots are sitting on a concrete floor, also my pots are fabric black, which in theory attract sunlight? but can that be really an issue?If they’re only 3 days old, it won’t take long for them to get used to the sun. Just start them off in some dappled shade for most of the day, move them out in the sun for an hour at a time, and monitor them. If they aren’t wilting and look fine, extend their exposure.
In a couple days, they will probably take the all-day sun. Just watch the temperature of the pots, if you’re using any. I understand that the Italian sun is hot this time of year.
What size bags are you using? One way to help cope with heat stress is to give the plant a bigger root mass. My greenhouse gets very hot as we are into our long, +90F days. My plants get sun from sunrise to sunset, I am at about 4000' , but the plants don't really get stressed too much because, being in the ground, their roots are massive. Also, panda film, white side up, makes a great reusable mulch, and you can put black side up on cool days.@fatbuds420 So, how are your plants doing? I’m an outside grower, in black fabric pots, in soil. Here’s my 2 cents. It has also been hot where I’m at, mid 90*F with the heat index up to 110*F in the shade. It’s just brutal in the sun and we’ve been affected by the Sahara dust that’s drifted across the Atlantic to the U.S. I have 3 big plants; a Northern Lights auto that’s at day 81 since sprout, and a couple of Mexican Haze photos, one at 90 days and the other at 70 days. They have all been outside since they were 7-10 days old. The NL can handle the sun & heat all day. The two MH can’t. They get heat stress and tacoing leaves if left in the sun all day. I have to move them in and out of the sun during the hottest part of the day. So it really depends on the strain and how intense the sun is where you are at.
I have my pots inside of plastic milk crates. They act as pot elevators to help in drainage and keeping the pots off the ground. I also wrap a light colored piece of fabric, like an old pillow case, an old cloth diaper, etc. around the crate to keep the pot and therefore the soil/roots from getting too hot. On small plants that don’t shade the top of the soil too much, you can spread some perlite on the soil to help reflect the sun if need be.
I hope this helps you. Good luck.
