trockene luft im wohnzimmer

hello and welcome to a new reptiltv technical episode. today's topic is ventilating your terrarium. you know that it is important that terrariums are well ventilated. reptiles need fresh air in the terrarium. if it had no ventilation, no ventilation grills and no ventilation, it would become a musty hole. there would be too little oxygen entering. therefore, ventilation is very important. of course, it is easy to make mistakes in ventilating.

generally, with most bought terrariums - and this is something i keep on saying - they are more or less wrongly ventilated. they always have ventilation points opposite each other. this causes a draught. imagine two windows open in your home, on the right and on the left. the wind whistles through, producing a permanent draught. here you do have fresh air in the terrarium, but you also have a draught, which is definitely not ideal. now i come to the second point, that there is not only a draught,

but all the heat, which you are pumping into the terrarium, is escaping, of course. the more the terrarium is ventilated, the more the heat escapes. the whole thing is a balancing act. if i put in a lot of ventilation, this may be very good for the animals, but i have to increase the heat in proportion. so, you must not simply overdo it. when i built my first terrarium, 30 years ago, i added huge ventilation grills and poured in crazy amounts of electricity and then i always closed the ventilation grills.

so in the huge ventilation grills, which i had built into the sides there were finally only a few slits left open, and the climate in the terrarium was still fine. it must also be said, the larger the terrarium, the larger the volume. the ventilation grills can be proportionally smaller, because the large space in itself prevents the air becoming stuffy. and i also have the sliding glass panels, which also allow air to enter both on the right and on the left. so don't go over the top with ventilation grills. this one in front gives a rule of thumb

for the size the ventilation grills ultimately need to be, since i cannot give you an actual rule of thumb. you cannot say this much air per volume of terrarium. on one hand, that depends on the animals. a dry terrarium for bearded dragons, etc. needs less ventilation than a humid terrarium, which quickly becomes stuffy. with the dry terrarium i also notice when it becomes stuffy in there. a good way of testing is simply to put your head in. if it is stuffy, or if the desert terrarium resembles a sauna,

then you have got it wrong and you must increase the ventilation. in this way you can test the technical possibilities. most purchased terrariums, at least the glass terrariums, have these aluminium perforated sheets. you can buy them separately and make two ventilators out of them. now i come to a very important point. i said before that most ventilation systems are wrong; they sit opposite each other. i've been preaching form 10 years now: install the ventilation on one side. with a glass terrarium, it is well-nigh impossible,

because that would weaken the terrarium. but the ideal solution would be, if i were to install one ventilator at the top and one at the bottom. then i would have ideal ventilation, without a draught. one at the bottom to let the fresh air in. in the terrarium the air heats up, the air rises and is pushed upwards by the circulation of air. if i install it on the side, i have air permanently circulating. you need to visualise it as a semi-circle, in at the bottom, out at the top.

and the terrarium is perfectly ventilated. the same applies to all types of wooden terrariums. so when you build your own terrarium, one ventilator at the top, one at the bottom. but not right at the bottom, because that is where the substrate is. so, just above the substrate. then there is no draught, but the terrarium is well ventilated. one way of doing it is the aluminium sheets, or these round ventilation grills have been on the market for several years. you need to use a hole cutter or hole saw

to install round ventilators like these. to give you an idea, with a terrarium like this one i would put a maximum of two ventilators at the bottom and two at the top and then the terrarium would be well ventilated. don't overdo it, two at the bottom and two at the top. with a terrarium of this volume the four holes will be absolutely enough. to make the point once more: you have to try it out. perhaps in case of doubt choose a larger ventilation system to start with. for example, with the aluminium perforated sheets, if you are building in wood,

you can cover half of these aluminium strips with masking tape, for example. if you really notice that you have overdone the ventilation, stick masking tape over half the strip, possibly on the inside and the outside. then you will have reduced the whole system and you will notice the difference in your electricity consumption. the smaller you keep the ventilation system, the less energy is needed to heat your terrarium.
