As ever, I'm not an expert with coco, but from my experience with it, it's rather spongy and, in some ways, retains water like rockwool.

With rockwool, one of the ways we'd get a suitable about of water in a cube was to saturate it, then give it a couple of gentle but vigorous shakes in the direction of the floor, which would relase well over half the water.
A 10cm cube could hold 250ml, whereas we liked them to have about 80ml when planting seedlings or newly-rooted clones. A couple of shakes was a good way to get them free of extra moisture.

I think if you soak the coco in the 2lt pots, then give each one a couple of downward shakes over the bath, they'll be left with a nicely moist environment that's not over-saturated.

I'd probably give the transplanted seedling a very light watering around their stem the next day, just in case the water in the pots has mostly migrated to the bottom of the coco fibre.

Maybe experienced coco-growers have a better method.

Well, if drying is a potential problem, you might want to experiment a little bit. Don't take the above method as gospel.

I always err on the side of not over-watering, but that's based on being able to tend plants every day. It might be better to err on the side of moistness for tiny plants that aren't being checked every day.

It has to be said, new coco-fibre does not get waterlogged easily, so shaking out the majority of the water might not be necessary if leaving seedlings for a couple of days. Just letting the excess run out with gravity might be enough.

If you have time, you could test this by saturating a 2lt pot of fibre, giving it a few hard shakes, then leaving it for 2-3 days in a place with similar temps to the grow room. If by the second or third day the top 5cm or so is pretty dry, that's probably a sign that the fibre should be allowed to retain more water.

After about 2-3 weeks in the new pots, this shouldn't matter as much, since the seedlings' roots will be nearing the base of the pot, so they shouldn't dry out easily. In the first weeks, their roots may not be deep enough to reach the residual water.

yeah munzy i fisrt wanted to let them out grow the jiffy then do it but had no other option as i cant tend the garden every day.
when i got there today my first seedling had drooped over so   proped it up hopefully be ok?
the one which was showing root first has now came out although very twisted looking so i tied it losley to a straw.
the other four are looking great, so i now have all in not 2 ltr pot as i first thought they are 1.5ltr.
i gave each pot a good water untill i got run off and added the jiffy which i gave a litttle water as well as they were very dry.
ill have my friend have a look over the next few days so hope all be ok.

your right ganja i should have tested a pot with coco first as when i got my jiffy i tested 2 of them just how u mentioned above.
the babies are now in there new pots and i took ur advise and shook some water of after i got run off.
4 out of the 6 are great the other 2 i will see over the next few days how they get on.
cheers

That's how I water seedlings and young clones in coco. Water to runoff and the give them a couple of shakes to get rid of the excess moisture. Mind you, I am talking about seedling pots (300-500ml).
