make sure there are holes (plenty) on the top of that enclosure. You want good venturri effect for these to be healthy

I agree that Cross Ventilation could be Beneficial.

Venturi Effect is a reduction in Fluid Pressure that results when Fluid speeds up as it flows through a constricted section of a pipe.

it is also used in construction and air flow. Differences in internal and external pressures creating suction / air flow.

"The Venturi effect explains the pressure difference around a building or in an interior and exterior of a structure and the natural flow prompted as a result of it. This mechanism can be exploited between structures to create natural ventilation during the design of buildings and walkways."

Utilizing the Venturi Effect for Natural Ventilation in Buildings

Taking advantage of the pressure difference and velocity change, constant circulation can be maintained in buildings using the Venturi effect for natural ventilation.

so holes on top cause a pressure 'draw' which pulls air through the bottom holes and out the top creating a much more active and dynamic ventilation

works the same as fluids as air functions as one.

yes, all based on fluid dynamics and their relationships to various pressures.

this works because of mechanical air flow.

no air movement in a house means no circulation. No matter how many holes you have. It does help for humidity to evaporate.

no humidity, no airflow, in those circumstances.

'Venturi tubes' are now used in construction for a mostly passive set up. It was also common in Craftsman architecture of the early 20th C with the concept of the Breezeway and roof or attic vents

Its good. We need ventilation. Passive too.

i was thinking mostly about those homes in tropical setings. They get alot of winds so is probably not as passive. But their construction is just like those eurostyle vivariums. Exoterra. I like those. I think they can work great.

i just hate that the mesh top is woven. When paying top dollar for an enclosure, it sucks to have to purchase add ons, or make mods.

i wish someone in the community made glass enclosure with euro style ventilation. With tarantulas in mind. Enough with the acrylics. I will pay twice the amount of an acrylic, for a glass enclosure that is exactly right.

diy containers are not as cheap as 10 years ago. And surely not as available. Tom moran talks of a nice enclosure on amazon, ten minutes later its sold out.

Anyways, back to venturi.

its just how my brain understands ventilation. Passive can work. Especialy with the movement created by heat. After all, these constructions are made to better regulate heat in the homes. That is my understanding.

no heat, nothing, just cold wet, might bot generate as much movement.

thats what i was trying to get across. Maybe my understanding is flawed. I do try to educate myself. But i can make mistakes.

to me, its not just one element. But the balance of all elements, that makes it work.

I am on the same page, and FTR I make replacement lids for Exoterras. That's how I solved the problem.

I will have to do that. I just don’t want to.

Trickiest part is working around the little nubs in the frame, I do both 8" and 12". The exoterra guys loved them and took my info.

and easy for me because I have machines

i dont have the machines. I envy all of you who own them or have access to them.

its not obvious for the rest of us, to get the same results. Its more time, more effort, more technique. Drilling into things is an art. We are trying our best in my home. Which is why we cant just buy any type of random plastic container. Not everything will allow us to drill and get nice neat holes.

if a person works somewhere they can do this, then surely they get access to scrap bits etc. The reality is, material has gone up in price. Drasticaly.

i cant afford plexiglass unless its the thin cheap kind.

personaly, i would buy a tailor made enclosure. There is an aquarium specialist in my locality. They produce museum grade quality set ups. I have not written to them yet because i fear my project is just a waste of their time and not profitable.

i will get around to writing to them anyways, because until i get a no, its not no.

but for now, its faunariums. And that has been the most anxiogenous thing with a p murinus. Its all been settled now. But that being said, it is worth investing in the right enclosure.

if i had just one tarantula, i would have spent all the spider budget on them.

i will, with time, be upgrading everyone. Because i love to see them tarantulate. And its such a feeling of success, when your terrestrial/burrower, is always at the mouth of its enclosure, looking radiant.

I design for retail display so I am around materials and machines every day. So I do all the design work than get on machines during their down time, or add them in the waste area of jobs. I only use the highest grade of flex and it is just under a 1/4 inch (.223). I was designing full enclosures
out of ACR but 1) I prefer the look and stability of glass. 2) I cannot compete withe foreign labor costs to be able to make them where I could compete in the market place. 3) I won't use cheaper materials to make them cheaper. so now I just do lids.
I am totally aware of the difficulties/costs of hand fabrication. I did a bunch of the cutting for a guy who builds cages so all he had to do was clean the edges and glue, I saved him probably 2-3 days labor and it took me about 1/2 an hour.
I can control bit direction, plunge rate, and bit speed to produce the best results, I can also add a cleaning pass. There's a guy who came from my industry who now builds really cool snake enclosures, The first show he was at I asked the people "I wanna talk to the guy who builds these"
because I could tell he got his start in retail display, we have ways we do things that is recognizable to those of us that do them. We had a great chat and he uses a machine that is the same as one of the ones at my shop. I have 4 in operation, for reference, those are 8' x 4' sheets in the photo

Do you have any exoterra talls?

 

[TheraMygalo]

I can get any exo terra. My issue is that most of my tarantulas are terrestrial. I do understand now that they won’t always climb. But if i were to cover the bottom layer of ventilation, then that would forfit the entire process.

I was also told one could put an exoterra horizontal. Im still not sure if i want to do that.

I just put together an enclosure for my almost 4” genic that’s a 12x12x12 Exo. Filled it up a lot with substrate and added “features” to fill vertical space.



And a 5” iheringi

It might just be what i end up doing. Filling the top with stuff in case they climb. Its nicely down, what you did.

A place i go to buy tarantulas has all tarantulas in such exoterras as “display” tarantulas. And there is more then 1.5xdsl. I think its all context, elemental gradients, etc.


I will consider this. Because in the end, the exoterras are really a good product.
