That bit of plastic bottle is too small imo. Get a proper pot or container like a yoghurt pot, maybe .25l. It MUST have drainage holes. Just fill it with seed sowing medium. Take a small pinch of seed between finger and thumb and sprinkle over the surface of the medium. Water from the bottom until it looks wet on the surface. That will be enough to bed in the seeds. I don't find any need to cover the seed. Put cling film over the pot and place somewhere warm and light. The seedlings should show in a few days to a week. Take off the film and remove from the bottom heat. Keep in a warm light place. When the seedlings are 2 - 3 cm tall and have at least 1 set of true leaves transplant to separate pots, or, and this is what I do, don't thin and grow them dense. Because, in my climate basil doesn't do that well because of lack of heat so the plants don't get very large. In your climate they may get big and need their own pots or in-ground planting.

Why not read through the FAQs here? They cover all the basics on how to grow anything from seed.
And surely you can find better containers to use than the plastic bottle you linked above.
But first you have to have mature, viable seeds. That means buying them or harvesting them only AFTER the plant blooms and then the blooms turn brown and dry on the plants.

What have you done to promote germination? For almost all iris including siberica, I like to give them a warm moist period of 2-4 weeks, then a moist chill of 40F for a month or more before bringing back to warm. Fall sowing outside works great in my Z8b. Not all seeds will germinate at the same time, they could be scattered over many days or even weeks.
No matter which iris, the seedling makes it's appearance like the tip of a pointy sharp blade of grass. Pics of iris seedlings here although not siberica but which will look same:

Hi Janie,
IâÂÂm growing Nicotiana alata âÂÂGrandifloraâ for the first time now. I started the seeds on March first and just planted two of the plants outside a couple of days ago; theyâÂÂre about 24 inches tall. I have one more still in the basement under lights thatâÂÂs about 20 inches tall.
The germination was fast (7 days) but I didnâÂÂt keep any record of their growth rate. As I recall, their growth rate was just normal, nothing especially fast or slow. If you started yours a month ago, they should certainly not be tiny.
What growing medium are they growing in, does it contain any nutrients? WhatâÂÂs your lighting setup? Can you post a picture of the setup?

I grow this plant every year and started them indoors. They were rather small when I first planted them outside. Maybe an inch or two. After the first year, they reseeded themselves in profusion and some also came back from the roots! I live in northern ohio so I'm about zone 5b or 6a. Once the warm weather comes, they grow very quickly and put on quite a show. Mine get 4-5 feet tall. Good luck!

Be prepared to wait about 4 years to get fruit from it though, and you don't know what you'll get since they're like apples and don't grow true from seed. Better to buy plants in 1 or 2 gal pots and plant those, or root cuttings from older plants.
Best site I know of for blueberry growing info is from U of Maine

I hope these aren't still sitting on a heat mat. If so, remove them ASAP.
No they are not big enough to plant outside even if the weather permitted. As Zach said they are very leggy so I would transplant them ASAP into somewhat larger containers and bury all that stem. While you can transplant young seedlings to containers at any time most wait until they develop some true leaves just to make them easier to handle. I wouldn't wait on these as they are going to start breaking over, The weak stem can't hold up the head weight..
But unless you can solve the light issue I'm afraid they are just going to turn leggy again.
Good luck.

Those are definitely etoliated, and will need hardening off if you want them to have any chance of surviving outdoors. Here are some of my plants under a t5 light setup where the seedlings are generally within 20 inches of the light bulbs. You can use metal halides, HPS, LEDs, or anything with decent wattage.
For example, I have 4X 50 watt tubes, and I still feel like I would be better off with a stronger setup.
These are angled luffa and tomato seedlings.



Sorry I think these questions were covered in your previous post about this. Didn't the "how-to video" cover this?
Whether they require cold stratification on not depends on the variety and you don't know the variety. If northern grown then yes the odds are they need it. If southern grown, probably not. Your choice. All you can do is try it both ways and see what happens.
How successful? Unknown since it is not the normal way to grow blueberries so it is seldom done...
It takes several weeks to germinate if they do and then several years before they produce fruit if they survive.

Stuck seed coats - aka helmet heads - require a very special method of removal. :) Spit, saliva. The enzymes in it quickly soften the shell so it can fall off or be easily remoned. Works better than anything else.
Just dab a drop of saliva on it wait an hour or so and it should slip off easily. Repeat application as needed.
1/4" long roots for just germinated seedlings is normal but should double in length within 24-48 hours assuming proper media and growing conditions.

Sunflowers are, in my opinion, some the easiest seeds to start. In warm soil, they usually sprout within a few days without any special treatment. Last year my toddler got ahold of a packet of sunflower seeds, I had them growing everywhere, cracks in the sidewalk, pepper pots, the pea gravel, you name it haha.
Id nix the soaking on those, since I don't see anything to be gained from it anyways.

Yes that is a good one. Thanks for posting it.
