Shade for seedlings?

I have my 3 day old seedlings (2) grown in Seedling mix 40 %,Perlite 30 %,10 % Mushroom compost and 20% used dirt from (ground outside) .
They are in Solo cups with bottle dome on them.Temps normally 30 deg,s most of the day as we are in summer in tropical FNQ.
My question is can I put my seedlings for the day outside under a shade cloth that is in direct sunlight.Maybe an hour, if not or two hours ?
I have never tried this before and will experiment, if I can with your answers. (Durbin Poison)

I wouldn't with plants that young. They're your plants do what you want. I'd get that seed hull out of there too. Its not helping.

Thanks Warble.Will get helmut off.I thought someone might have tried this ,they are young for sure.I realise I can do what I want but asking questions that are not written anywhere will hopefully help others as well as me. ,I,ll take your advise at this time of there journey.The humidity inside is 60 + so was looking for alternatives so hence outside.I can not shell out for a humidifier,I have fans helping to bring it down.thanks again.

Bringing plants outside is a big no no if you are not planning on leaving them out there. Do yourself the favor and get a cheap humidifier. Or set up a wire dome over a 5 gal bucket with a wet towel over the dome and the towel dipped into water in the bucket. Then point a fan at it.

When you bring plants outside, it's an open invitation for a free ride to pest paradise. Perfect conditions, no preditors, plenty of food. Once you get mites, you will never bring your plants outside again. Save yourself the pain and agony and leave them inside.

Take the domes off too, or you will damp off the seedlings

Dome gone,will be outside on verandah when in vegetation,but will keep inside for another 2 weeks
Thanks cannabiscrusader

Girls where looking a bit hows your father,so tried them under the shade cloth for 1/2 a day then into the sun for an hour first day and so on, know they are looking ok.
Shade cloth works in the tropics for me, but get that sun into them.(5 days old.)

Still very young, but starting to have a dangerous stretch to them. Under ideal conditions one should not need to stake them, especially that young. What is the light source? It sounds like your intent is to be 100% outside for the life of the plant? If that's the case then hardening off the plant is a decent idea. Not sure how things grow in the tropics but id be more inclined to just have a dome on it vs a shade cloth. That way your trapping some of that humidity in there and you'll also notice you wont need to water often at all.
I see you mention about the humidity being 60 but then talk about using fans to bring it down? In that stage you want like 70 percent humidity.

I've only used a shade in the grow room i've not personally used it in sunlight.
For light can't see a problem, the pests it'll pick up would concern me more.

What you said sounds OK,they were under dome for first three days.They looked a bit ordinary, as not reaching out.I nervously pro acted and gave them two hours of shade cloth then an hour of sun.The latest pic they are reaching out and doing a lot better.The seedlings were under a fluoro,they grew tall early but got them closer and stopped them stretching any further.Tiny bamboo slithers used to support,so will leave them in till transplant.Hardening off is happening as we chat.Yesterday they spent morning in the sun then a break then afternoon sun.The wind was blowing a little so steaks helped for sure.(They are Durbin Poison)Today they are 6 day,s old .A strain from 45 years ago even longer, when I was younger.ha

Will be on verandah for life.

Never used it in sunlight either but it worked like a ripper.Sun is good even if shaded slightly.

Putting the seedlings under shade cloth worked out great,plants are know flowering and ready to come down in about 7 day,s.1 Female loaded with DPoison seeds.The shade cloth with the sun,s help was great.

Looking a lot more like 3 to 4 weeks than 1 week. You don't want immature seeds.

Seedlings are quite capable of all day sunlight. Think about it.... What they can't take is root damage. That small cup will get hot, and the roots burn and the plant dies and people think OMG the sun killed the leaves. NOPE !

Not what happened. First off your plants are suffering from solo cup poisoning. They are designed to drink from and are too tall with a to narrow base and all to prone to falling over. Buy some honest planter cups from the nursery 3x3x3 inch square as the shape promotes better root branching and limits the coiled tap you find when transplanting from a round pot. They are still small enough to dump out and repot with no harm.

Simply cover the pot with a board or a scrap of towel or fabric. Anything to keep the pot and the roots inside it cool and kept from direct sun. Even dig a cup sized hole in the ground or a bigger pot and drop the cup in during its time outside.

I have red cups and someone posted putting clear inside and a couple of small pebbles between red cup and clear.You can see root deveopment.(Can not see develoment wth 3x3x3 pots).Seedlings they are so young all day sun will bake them at 30 plus degrees,Hour or two max first 4 or 5 days,using shade cloth was something experts could not tell me if this would work.After shade cloth it has proved it works perfect .Shade cloth works.Sun is a big part of my grows as on verandah.I move around verandah chasing sun.I Strongly disagree with most of your comments.Long live red solo cups just the rite hight and do a great job replanting with there shape.Coiling never happens with seedlings as re-potted within 3 weeks,we are talking seedlings not vegetative growth.Only time I have seen coiling at the bottom is when it is in veg.seedlings suffer from all types of stuff not just root damage.thanks made me think anyway.

There is no such thing as "solo cup poisoning" lmao unless you drink too much alcohol out of one. They work just fine. When seedlings emerge in the spring, days are shorter and light is not as intense as mid summer.
