Question about wind.

So, I built myself a giant grow tank. It is bright, lovely, and very neat.

 

My highs are 29-32C

 

My lows are 21-23C

 

Humidity is 70-99%

 

 

But, the way I managed to get my temps and humidity constant is to install a decent size fan that keeps the air moving. My question is, how bad is the constant wind? They aren't getting blown around to the point that pitchers are flopping in the wind or anything like that but, the leaves are constantly shaking. Is this an issue or will it just help to insure that the plants are tougher to put up with the wind?

 

All plants are Lowlanders.

Hi Mdeford09

I can't comment on growing Lowlanders but when I grew orchids in a green house I used fans 365 days of the year and the plants in front of the fans never suffered. I would imagine Lowlanders would be the same, as long as they are not rocking in their pots and becoming loose in the substrate I regard air movement as a good thing all round.

Ive never used fans in a lowland tank but i doubt it will do any harm. Wind reduces the effective humidity (not the humudity you measure). Some orchid growers use it to prevent mould etc. with some indochinese nepenthes in particular i find they dont pitcher well unless they have very high (~100%) humdity and mould (on the plants) has never been an issue. In fact the high humidity seems far more important than high temperature in getting growth for some of them.

So basically i doubt that the wind is a problem but if you find they struggle to pitcher, turn it off.

Thanks for all of the info everyone!

 

I may go ahead and try the timer and see what happens. The issue I have found is the heat moves quickly. I actually had a couple of 120mm PC fans installed but these couldn't even push the heat down. So, I am worried that leaving the fans off for 15 minutes would just cause the top of the tank to reach 38C+ and the bottom go back to room temp.

 

Only other option I can think of is to make my tank 2 individual tanks. It was much easier to control when the tank was smaller.

 

 

Here is the list of what is in the tank.

 

N. Smilesi
N. Gracilis
N. Trichocarpa
N. Hookeriana
N. Rafflesiana (pink)
N. Rafflesiana (Green)
N. Bicalcarata
N. Ampullaria 
N. Hookeriana X Ampullaria
N. Campanulata
N. Viking x Tiger
N. Dyeriana
N. Merrilliana
N. Hirsuta
N. Hispida
N. Albomarginata
 N. Rayong x Ampullaria

I have fans almost constantly in both my highland and lowland tanks for quite a while now. I've seen no ill effects. (Frankly, it keeps the mold/algae down). I would guess that it would depend on the size of your fan and the power of the wind. I'm using a computer-sized fan for 40 gallon - 55 gallon tanks.

Well, I had two 120mm fans and they didn't do any good (standard size for a PC). I then stepped it up to two 200mm fans and they couldn't do it either. So, I went and bought a 12" metal fan at Walmart for 15 bucks... I have it set to low because it seems to move a ton of air. But, it works and keeps the heat from pooling up in the top half of the tank.

 

Total size of the tank is over 300 gallons, lol.

 

But, I have positioned it in such a way that the fan is not directly blowing on any plants. They are just getting the air that is bouncing around the enclosure. I will let them go and see what happens and post the results. :D

 

Thanks for all of the advice!

 

 

Here is the tank, incase you guys missed it in my other post.
