    This is the first time I've run into this problem and most of my established pots have enough other top dressings that it hasn't become a problem.

    Any ideas for small clips fans? I would use a computed fan but do not want to mess with any wiring.

    The mold and fungus is common on pots that have not had their peat "washed" before use. This often kills my plants.
    As for the dews, i've found that the alba form of capensis likes it cooler and will produce smaller leaves in bright light - i grow it like adelae, or prolifera. Red capensis are more prone to shock, but the lack of dew on your typical seems distressing. It's probably not the temperature or humidity, but the lights. I don't know what kind of outage your T5s have, but i get the feeling that they aren't as powerful as T8s. I've stuck with the same lights for almost 7 years now; never known anything outside of T8s (i think that's what they are) and a 400 watt metal halide.
    I recommend getting new soil for any concerning plants, definitely for the new ones. Clean your trays. Don't use any of the old soil unless it's been baked. Recommend washing the trays in isopropyl; not required, but it's pretty much guaranteed. If you want, use sphagnum as a medium. It keeps the mold under control for most sensitive drosera.
    Fungus takes effort to grow rampantly. It usually won't spread, but check all pots; it grows from the bottom up, and the effects usually are gradual.
    The mold might be killing the roots; this could explain why the symptoms of your plants are so similar to lack of water and root rot.
    Jus mah two cents. Nice set up, brah!
    Forget about the mundane and meditate.

    Few notes as I have gone through the transition to tanks and found such problems myself:

    1) The media. That is a critical component. Did this media (exact brand and ingredients) in the previous setup did not cause any similar problems? Bad quality peat with nutrient additives can cause issues. Also in that pic of the media, the media looks crumbly. Thats not good for CPs. Its fine if it only occurs once every week or so when the pots dry out.

    2) The black water with a almost film of slime. I get that in my two tanks. I have trays at bottom. I never took pics of it, but probably should sometime. I clean them once every 4-5 months. The water is exactly like that. BLACK peaty water with slime algae growing in it. Also note that I see it in a tank that has no PEAT based media. Sphagnum/bark media also produces the tannins that causes the colour.

    With regards to these two factors....next time..check if the media pots have a distinct stinky smell. Fresh peat has a very distinctive (IMO fantastic smell). As time passes, the smell goes away, but if the media compacts, it gives a stinky rotting smell. Also..when in good condition with adequate air circulation, the water should be clear light brown that is the sign of healthy media.

    Biggest concern here is tank. Having grown sundews and VFTs in a tank and then outside in a tray under light, I must say, they do waaay better grown open than in a tank. Many sundews come from dry areas of our planet and do not like the stale air in tanks. However, if u still want to try this: Arrange your pots closer so that you have an empty area on the tray. Make 4 stilts and place a computer fan facing downwards into the tray such that the air circulates between the pots. It will definitely take care of a lot of your fungi/algae problems. I think this should be your first priority after ensuring media and water quality.

    Thanks for the help so far everyone!

    The media that looks "crumbly" is from the supplier. I will definitely repot those plants using my own media which has yet to fail except for whatever reason in the pygmaea pot. My fault for assuming it would work...

    I would definitely grow these guys outside, however as I learned last summer when I tried a temperate mini-bog, there is absolutely no place around my house that gets enough sunlight for a decent enough time to try growing cp's outside. Not to mention trying to transition them while in the very hottest time of the summer probably would not end well. If that were not the case I would already have several Sarr's in my collection

    I will try to get a fan in there somehow as soon as possible though.

    Oops, forgot to mention I probably will still use a fungicide on the pygmaea pot. They are just too little to try to transfer out and repot.

    Also, I am seriously thinking about using that extra shelf space I have for some CP's that would be able to grow in a room setting. Typically 70-80F during the day, cooler at night, and humidity hovering around 50%.

    I recently added a CPU fan to my terrarium and have noticed quite an increase in my plants growth. I have always used them for my orchids but decided to try it with my CP's too and glad I did.

    If you want to look into using a CPU fan send me a PM and I can step you though it with pictures if needed. It's really very simple.

    Beware you drinking water may also have added minerals, but those usually aren't a problem. But, if you dont some live growing sphagnum, then they will be in the future.

    Well, first good sign...after moving the typical back a row in the tray the newer leaves are showing some dew. Might take a bit more rearranging once everything settles in to find the right combo.

    I was going to repot everything today but I want nothing to do with mixing up media outside in this weather...supposed to get better as the week goes on so it will get done soon!

    That would be excellent. I am a pretty visual learner so pics would be much appreciated!

    No mention of any added minerals on the labeling but I haven't tested TDS either so I can't be sure they are none either.

    As for live sphagnum, I will consider it in the future.

    Affected plants were repotted. A definite earthy smell with my mix
