Guild design for a Colombian greenhouse

Hi everybody I am a retired Marine Biologist, getting certified in Permaculture. I am trying to develop my certification project on a place in Colombia (coffee plantation area) on a special need children foundation. They have this incredible green house.  They have being doing ok with Monocrops and have produce some green and tomatoes. I got the ok from the persons that administer the Foundation to get this place to another level. They use commercial seeds, compost all kitchen vegetables leftovers. We want to create a self sustainable organic crop place.
I am looking for ideas on guilds, if you can guide me in that dirección I will appreciated. Cover crops and plants that produce material for mulching. Plants that attract pollinators, insects etc.
I am pretty new but very exited. The green house is open and is about 30 x 14 meters.

In cold places like USA and Europe, greenhouses are used to grow tropical things like bananas.

In tropical places I can see a greenhouse being used to grow drugs like pot because it makes it harder for other to see or smell it from a far, and thus there is less lost, so they use it more like a privacy/security structure but at the expense of having to use an AC unit to cool it and also having to burn fuel to make the structure have more carbon dioxide.

If it was a full desert, I can possible be the structure being covered with shade cloth to cut down the sun, but I am not sure I would still call that a greenhouse.

Maybe your location is super cool like Chimborazo in Ecuador. Or maybe you have a series of small greenhouses and you want to do some strict cross pollination to develop new cultivars/strains.

I would love to hear about other use cases for greenhouse in tropical environment, because I am not too experience.

Now for the original question about guild species/cover crop species/support species. These are my recommendation:
Nitrogen Fixer: subterranean clover, pigeon pee, legumes, etc
Pest control via predatory insect housing and pollinators: mint/thyme family and carrot/celery family and other traditional herbs/teas
Soil nematode pest control: onion/garlic family, mushrooms like oyster
Soil aeration/mineral accumulator: daikon radish, and others, fungi/mushroom
Soil Organic: grass family

I think the purpose of the green house here is because sometimes we can have very long rainy season, so to cultivate vegetables and herbs they prefer a place with a roof. This actually doesn’t have wall is open. The entire area is 2 hectares, they just plantea 50 fruit trees, and it has a little forest on one side. I wish I can post more pictures I’ll see if I can. Thanks Bengi for the advise I’ll keep in mind, lots of space to grow food for them. This is a foundation for mentally challenged children and adults is a great cause. I am learning so I will try to keep new post thanks again 🙏💫🐬
I guess you are right I shouldn’t call it green house, is more like a covered food forest 🌳

Ahh, its a Shadehouse. That helps to keep vegetables tender and less bitter.
And with it keeping the grow area dry and tidy it's perfect for the clients/population that will be using it.

It makes alot of sense to use it.

In that greenhouse, I listed: herbs, teas, legumes/beans and mushrooms, but I didn't list any vegetables or short berry sbrubs.
For vegetables we have the cabbage family and spinach family. And then for fruits we have the tomato/nightshade family, blackberry sub-family, maybe grapes and vanilla beans could be added too, guava and pomegranate are relatively short. I do like eating sugar cane. What other fruiting plants would you include?

Thanks where are you located?

I am near New York City, USA (by near I mean 200 miles to the northeast, lol)
But I have some "tropical" experience via Florida, USA, and Caribbean Islands

In a greenhouse/vegetable setting we tend to use the phrase companion planting vs guilds.
The rules of thumbs are:
beans provide nitrogen/fertilizer
thyme/mint herbs are good esp with cabbage family
celery/cilantro herbs are good similar to the mint/thyme family
onion/garlic family help with nematodes (soil-root pest) but hurt the bean family
Tansy is similar to the onion family in function but doesn't hurt the bean/legume family

Thank you Bengi, great brochure for planting will keep in mind. For now, I am focusing on mapping the land and do inventory of trees.
Need to plant mulch creating plants (I read that Comfrey, Lemon grass and Thyme works)
and create a system for producing Bio-fertilizer because they already have a great compost system, they used all their kitchen scraps.
look at this Guy from Colombia, he has property in Colombia and Teaches in Africa and Europe. Is a recipe to produce Bio-fertilizer.

How can I posted more pictures?

My Version
Purple Non-Sulfur Bacteria (Worm Compost or Pond Water or Aquarium Water
Lactic Acid Bacteria (Milk or Whey or Milk-Kefir or  Stale Rice-Wash Water or any live ferment)
Yeast (Kefir, sourdough starter, stale rice-wash water, kombuca, bakers yeast, etc)
Chitin Eating Microbes (insect Frass/Shell, shrimp/etc, dried mushroom)
Indigenous Micro-Organism (Compost, Cow-cakes, etc)
Now its time for food so that the microbes can multiply (molasses/dark sugar, insect frass/chitin, rice flour, fresh cow manure because it isn't too hot)

This can be made with a airlock aka anaerobic similar to making alcohol/kefir or like in the video
Or it can be made with a airpump aka aerobic  similar to an aquirium setup, but you will need to clean the bubbler after each brew (2days-4days)

Personally I prefer the airstone/aerobic version it doesn't stink and the ultimately mix of microbes is more diverse and healthier but they both beat doing nothing esp in drought conditions.

Purple Non-Sulfur Bacteria: These guys are nitrogen fixer and they produce good compounds
Lactic Acid Bacteria: produce vitamins and other good compounds for the plants
Yeast: outcompete bad microbes, provide food for other microbes, makes minerals more bio-available
Chitin Eating Microbes: create compounds that when sprayed on leaves, kills/hurts/discourage pest like aphids/etc
Indigenous Micro-Organism: This is where the magic happens, if your compost is made with more woody material, then it would be more fungal, or it could be made from weeds/vegetables or in the middle with cow-cake/rice.

Others: baked egg-shell(just like when making milk-kefir) or rockdust can be they turn into bio-available mineral and provide a ph buffer for the 'tea'. You could probably add some slugs too to multiple slug killing microbes or another pest.

Thank you those are great tips 🙏💫🐬

Do you know about slug-killing nemotodes and if they are native in the USA soil to grow your own?
Here is the thread I started on it if you want to hop over there to reply.

Thank you again Bengi, Fortunately we do not have slugs in the area. The preparation you mention looks easy to do, more information for my book of remedies. Again thank you so much
