It wouldn't make much difference, this NG has more emphasis on fruit and
vegetables but that is not OT on the other group. On aquaponics there isn't
much talk on either. On geocentric domes there is unlikely to be any at
all. If you mean geodesic domes that could be more fun.
Terribly inefficient in the real world, where joints leak and products
don't come in triangles. So unless your reason for being interested in
them is "pure cussedness" realize that a normal-shaped plastic film
covered greenhouse will cover ground far more reliably and cheaper, in
this world, anyway.
As for the less agricultural uses, the writers of the dome home book
have publicly renounced the darn things, but evidently a whole new
generation of people that don't want to learn from the mistakes of 45
years ago is raring to build the leaky, noisy, unpleasant things again.

I would be surprised if there are too many commercial greenhouses that stray
from either box structure or arched roof design. I gather there are some but
you need to ask why you want one.
DIY greenhouse designs are mainly hoop houses. That is a rectangular floor
plan with an arched roof and sides built of bent members - usually polymer
tube. You will find many plans for these on the web. They have the
advantage of being fairly cheap and simple to build out of commonly
Geodesic designs allow you to have a roof with no internal posts at the
expense of the self-supporting dome shell being constructed out of planar
polygons - mainly triangles. It is hard for me to see why you would bother
as there is no particular problem with internal posts in a greenhouse and
making a self-supporting dome out of triangles requires unusual structural
members and forms that are not at all readily available and that would be
quite hard to fabricate yourself. Another issue is the covering would have
to be manufactured by joining many triangles together. This is an added
expense and every seam is a point of weakness. In the more traditional
designs the number of seams is far fewer depending on the size of the house
compared to the size of available polymer covering.
If you are going for the coolness factor or you have some special aversion
to internal posts by all means but I am yet to be convinced the design is
very cost effective for this application.
We haven't built one yet, but my husband has been researching them to
see if one would be useful for our small back yard. He's shown me some
videos on how they are built and covered, too.
We're urban farmers on a small scale, and have a large back yard raised
bed garden on one side of our back yard, and on the other side we have a
chicken coop with laying hens. Between the garden and the chicken coop
we have a small greenhouse where we overwintered some peppers, and other
container grown veggies, including a couple of kumquat plants, a lemon
and a lime tree. My husband set up an aquaponics area where he raised
fish and pumped the fish water into grow beds above the fish containers.
He raised lettuce, and some strawberries and other similar veggies
during last winter. Eventually, he went to raising tilapia and by
spring the fish had outgrown their tank in the greenhouse, so he bought
a larger tank and now has a large setup in the middle of the back yard
where he's raising tilapia, and they've been breeding, so we also have
various size fish now.
Since fall is on it's way, he's moving the smaller fish back into the
small greenhouse, and putting the really tiny baby fish into the sump
that feeds the tank there. Now, he's left with the larger fish that are
still outside and he's wanting to build a dome over it for the winter.
I'm not sure that's going to work, though. I was looking for other
ideas and thoughts on what we might could do.
thanks for any suggestions.
