Hi everyone, 
So I've been doing some research and it looks like many people recommend repotting fly traps yearly. I feel like this is too much work(i have around 100 plants and im a full time student) and waste of medium(peat & sphagnum), so is there any method that will still allow the plants to thrive such as by only changing the top or lower portions of the potting medium? Would it have the same effect when simply unpotting, loosening the mix, then repotting with the same mix? And how can you tell when the medium is not good anymore? Will the repot drastically change vft growth? I have watched the relatively recent video made by FTS relating to this.
Thanks.

I repot every 2 years for all my plants. I have heard of people using sulphur chips or something like that to prevent the media breaking down in bog gardens. I have not tried it before so don’t take my word for it.

Hmm yeah, I'm thinking of taking the repotting every 2 years approach, or at least repotting only my favorites yearly.
Does time of year affect the growth of the vft, so if I were to repot middle of spring would it be better for my plants health if I just left them in older medium than repotting during the wrong time? Had this happen last yr where i repotted some flytraps middle/late spring and they went dormant all summer? Never knew this could happen or what exactly triggered this.
I know the plants are supposed to thrive much better with fresh media but how much?
What benefits most, the size of the traps or the amount of growth/divisions the plants will put out? These are some thoughts I've had when deciding which plants to prioritze on my spare time.

The smaller the pot, the faster the soil goes "sour". You might be able to get away with 3 years, but that's really pushing it. When this happens, you won't have any trouble recognizing it: the plants are very reluctant to grow, the petioles are short, and the traps are small. When you unpot them, you're likely to find a bunch of small divisions. I had this happen with my A2 and Grün plants last year.

I try to repot my plants in late winter / early spring, but I haven't had many issues with doing it at the height of summer when necessary. I found that it's best to keep the newly repotted plants in a low-light area for a week or two so they can get settled in, then start acclimating them back to full sun. I didn't do this with my big pot of Low Giants last year, and they sulked for the rest of the summer.

After I repot my flytraps, they usually put on a burst of new growth (more/bigger traps). Divisions usually come along later after the plants have been growing and eating for a while.

I repot my temperate plants once every two years, that seems to keep the media good for them. It’s a different story for tropical plants that aren’t exposed to the elements, I don’t feel that helis need repotted until they outgrow the pot. Media seems to stay fine for them.

Repoting is necessary to keep your plants in a good condition as the substrate in the pots loses its acidity with water washing through it over time, this elevation in PH allows the medium to degrade thereby releasing nutrients into the pot making matters worse. As it degrades the soil 'grain' size gets smaller and it compacts, so it is more difficult for oxygen to permeate to the roots, all in all the plant looks and is more distressed as time goes on.

So in answer to your question, yes repotting as you have found out, can cause set back to your plants, repot in Feb or March to minimise this. Taller pots produce better specimens, don't just use your existing medium to repot your plants otherwise the only benefit will be additional oxygen to the roots which probably won't be good enough. At the very least mix it with new peat and or pine nuggets and check the PH if you can, or grow in pure live Sphagnum if you can stand its invasive nature for VFTs then you need never repot .
Cheers

Scatter it to the five winds in an offering for their blessing on the newly planted babies. (Okay, I chuck it in the backyard.)
