I am not so sure it is the water (well, maybe in a way kinda...)- I think the Sphagnum is doing something (I have no particular reason for believing that though).


    Uh.... well...

    Sounds like you have a dang good solution here
    I'd love to keep them in their pots though haha. They'll get mixed up and misidentified in the Sphagnum cultures, and when I want to harvest it will get messy.

    Do Drosera usually like to be standing in a lot of water or not so much? On a pot, how far should the water come up to at highest? 3/4 of the way, 1/2 of the way? What works for your major Drosera growers?

    Haha. Well Pine ole boy I have no solution other than stick with the sphagnum. If its seems to work then I don't see any reason to do anything else.

    I do actually know the purpose of the shade cloth. I was just suggesting the idea of it working too well.

    EDIT: Just put the cultures inside the pots!

    It just doesn't make sense because the place I got them from grew them in the same trays I use. It has to be water level... At least I think. Again, does anyone have information regarding proper water level in ratio to pot height? Do Drosera like to be in a lot of water, just a little water, should the trays dry up before watering? It is worth a try to adjust my watering schedule.

    I keep mine in a tray with the water at 1/4 up the pots give or take 24/7. At this moment I have out 10 plants half are flowering. Try that out. Also my plants are on a 16/8 photoperiod so maybe that is a factor...? Humidity ~50% at all times.

    water level would depend on the soil mix. heavier mixes will be able to wick moisture higher above the water level compared to lighter aerier mixes.

    i use 1/4 pot height for my water level using a 2/3s peat to 1/3 perlite

    Thanks! I'll try adjusting water levels tomorrow. I think most of the pots are pretty much pure peat, perhaps a bit of perlite, not much.

    When you put them in the sphagnum, do you take them out of the pots and then plant them in the sphagnum? I had read it as you were placing the potted plants in the sphagnum. If you are taking them out- I wonder if your soil is perhaps too dense. Of course- Api's suggestion is good. If they like the Sphagnum- why not pot them up in sphagnum?[/QUOTE]

    I think it depends on the particular species. Most of mine, I am a little more conservative on the water. The vast majority of my Droseras are either Australian or South African though (I do not have a single North American species Ironically). D. spatulata for example- dies a miserable death in my care. I have been told D. spatulata almost likes flooding.

    "My Nepenthes are receiving enough light as well as the Drosera in the Sphagnum cultures which are also under the shade cloth. If they weren't getting enough light, I wouldn't have even bought shade cloth. I have it because there is too much light."

    I am starting to wonder about light though- are they producing dew at least? When you say the species in the Sphagnum are getting enough light- are you comparing identical species in and out of the sphagnum culture? Same amount of light? If so, I would also consider the humidity levels. 60% RH seems fine to me but I would expect that the ones in the Sphagnum are at a slightly higher RH. A good test of this might be to put a potted drosera (assuming you are placing pot and all in the cultures) in a plastic bag and mount it in the culture as you normally would- see how it responds.

    then id go a bit below 1/4. pure peat can wick moisture very very easily
