Having trouble

Hi:

I've lost P. cyclosecta and P. primuliflora to mold.

I've kept them in a tray that I added water to every other day. Is this too much humidity for these particular species? The others are still looking good and even showing a bit of growth.

They're in a mixture of 1/2 lfs and 1/2 perlite.
 
I have never grown P. cyclosecta.
I have failed twice with P. primuliflora to rot. I can grow them good spring to fall but winter they rot. So I gave up on them.
I grew them outside where they received early morning and late evening sun and were shaded from the midday sun.
 
How much light are they getting? My best advice would be to "up" the light if possible and lower the humidity a bit if you are growing them in a terrarium.

P. primuliflora rots alot anyway.

promuliflora tends to rot fairly often anyway, but they tend to rot less often in pure lfs

As for P.cyclosecta, that is a mexican Pinguicula and that mix is far too wet-I remember telling you this before!
A good mix for mexican Pinguicula is 1:1:1 peat, perlite, sand or 1:1:1:1 peat, perlite, sand vermiculite
As a general rule, mexican pings like very good drainage
I would repot your other mexican Pings into the one above mixes(though I usppose you could swap the peat for lfs) or they will rot sooner or later too
Trust me, Ive had my mexican pings in a mix like that before.....and I lost a lot to root or crown rot
But since Ive changed to using 1:1:1:1 peat, perlite, sand, vermiculite, I havnt lost a single one to root rot
 
I have mine in a mix of sand & peat, topdressed with LFS, open tray. I water twice a week and haven't had any rot awat, though I do see an occasional piece of mold, that is easily removed. Light, air circulation, and letting the water level vary seem to work.
 
My first P.primuliflora rotted within two weeks sitting in 2" of water in a terrarium with good light and air circulation.

I've had my second one now for 3 months and it is very healthy and producing plantlets. It's in the same terrarium and the only difference is that it isn't standing in water anymore. I water only to keep the soil just moist.

However, as JLAP said, P.primuliflora is very prone to rot and you may have just been unlucky.

And Jim, I'm glad to hear your primulifloras are still doing well. I'm going to acquire another and see how it does outside of a terrarium open tray under fluoros.
 
I have my primulifloras in a terrarium potted in pure LFS and is kept just moist. They can handle various light levels from bright indirect light to 6 hours of direct sun. They grow best under fluorescent grow lights though.

You are very lucky to get a professional informations from all specialists.
All of that which is the main points about your questions.

I hear lots of "they rot often", and etc. when referring to Pinguicula primuliflora.

What I actually read from that is; "I don't give them as much light as they need, so they rot for me." If you give them as much light (PAR) as is optimal, you can keep them floating in water (such is their natural habitat) and they will grow and bloom nearly continuously, as mine have for many years now.

When giving them lots of strong light, don't forget not to ever let them dry out, not to let them get too hot (don't cook them), and to feed them a little from time to time.

I'm growing a rescued ping from Home Depot (was called a starfish plant but it looks like it is primuliflora, it had a purple flower). Anyways I'm growing mine outside in a tray, on a lower shelf that doesn't recieve full direct sun. It is doing well, catching its own bugs, sprouting new leaves, and it even has a pinkish hue on the edges. I'm using a mix of 50/50 pete/perlite and a top layer of LFS. I would never suggest planting any CP in a 100% mix of pete moss. There's just no drainage at all, and your pot tends to flood.
