Given good conditions it will bloom next spring, but fruit formation will depend on  formation of complete flowers with mature styles.

Precocious one starts to flower when about 20 cm tall, but fruiting is delayed, most fruits appear in 3 years, many early flowers are incomplete. At this age the second flowering in summer is giving some fruits, but they do not have a time to mature in the open ground.

I believe your plant is IVIA358

Fruit of my IVIA358 as of today:

"forma achatada y estilo persistente" (flat shape and persistent style)

The leaves are not fully visible on your photo. Could you please make a picture from the top.

it is interesting that all different FDs gave standard PT seedlings. Do you think the seedlings are F1 or the mother plant?
My FD is not giving standard poncirus seedlings, only distorted ones.

Your seeds were probably from a hybrid of FD with ordinary poncirus. It looks like FD but at next generation is giving predominantly wild type PT seedlings. My pure FD is giving only curved seedlings, some extremely dwarf, but all of FD type.

From what I read in other forums, the main problem with such systems is water condensate being formed underground. It should be drained somehow and it is not an easy task in heavy soils and high water levels.

This variety sometimes is called Pavlovsky pomeranets. Normally "pomeranets" is a Russian name for sour orange, but for taste this variety is more on mandarin side, with only small note of bitterness.
That is why it  is alternatively called Pavlovsky mandarin. Nobody actually know its precise origin, probably some sort of hybrid seedling.

Bred for indoor greenhouse growing at 55N without any supplemental light?  Wow, impressive.  Will definitely research them.
Not even for greenhouse; just south facing house window

There are two citrus varieties that were bread for low winter sun indoor conditions: Pavlovsky lemon and Pavlovsky mandarin. But of course Pavlovo at 55N is far from Reykjavk at 64N

Yes, yours is 358, IVIA235 has small flowers

Yes,  they were grafted on poncirus.  Which IVIA variety do you have - IVIA358 or IVIA235?
Below is a flower of IVIA358

It was  destroyed up to the roots, started to grow next summer, but was killed  the following winter.

Was it flowering at his garden?

It is probably another variety, since tetraploid somatic hybrid has only  trifoliate leaves

I really do not know, most probably actual budwood is from Andi Voss plant.
In a literature there is description of tetraploid hybrid obtained by somatic cell hybridization.

I have it, got the wood from Robert (Zitrusgaertner) in 2012. On own roots it is not enough resistant and grows rather slowly.
In 2013 I low grafted it on poncirus, it is in ground without protection since 2014, no winter  damage up to  now.
It comes probably from a free  pollinated immature seedling of initial hybrid , since only a small number of  leaves are trifoliate.

Approximately 1.5m high, but has not flowered yet.

I lost Ichangensis from B.Voss several years ago when winter was mild, followed by one night  of  -6C  in the beginning of April.
Another ichangensis (SRA241) in open ground, without protection; had some branch damage last two winters.
You should probably plant it in a shadow to minimize temperature fluctuations. 

It is certainly very hardy when fully resting.
The problem is that its threshold temperature for vegetation start is less than that for poncirus and its hybrids.
In climates with large  winter temperature variations it is damaged even before citranges.

Look more like  citrange.

The moment for the optimal pollination corresponds to appereance of sticky moisture on stigma.  It depends on variety and environmental conditions, but pollen  can be placed before the optimal time, actually  to achieve good fertilization it is better to pollinate the flower several times.

I do not understand why you are blocking some posts or moving them elsewhere?
What is an idea behind moving a report on this year hardy citrus survival to the main Tropical Fruit Form?

And I forgot to mention the biggest surprise: unprotected Keraji (low poncirus graft, budwood from Tintori plant)-  no damage at all :o
