    Need N. campanulata pollen

    I have a male campanulata which flowered in autumn 2017. Maybe it'll make another flower this year.

    Anyone guess what these are?

    How are you tadpoles doing? Have they become frogs already? Mine are out of the water for two months now and, as they believe they are now toxic, are becoming much more visible and bold. I'll snap a few pictures in the next few days when I see them.

    Nepenthes Nepenthes rajah x veitchii conditions

    I've had one for over a year now. It's a fast grower and does well in intermediate to highland conditions. I grow mine on a windowsill. Unfortunately mine got burned rather badly this summer during a heat wave. We opened the windows but the plants were not accustomed to direct light (with UV). It's recovering well now but had a setback.

    They are now in their home for the next 4+ months. All three have become fat healthy frogs. They're very shy for the moment, but this will get better as they grow a bit bigger. Surprisingly their pattern is still slowly changing and, according to some froggers I know, will keep changing until they are 6 months old. Manders, how are your tadpoles doing?

    An update: All the tadpoles of my first batch are going through the morphing process.

    What do you do in real life???

    I worked as a molecular biologist at the entomological department of two musea for a year and am currently doing a PhD at the University of Antwerp in soil microbiology.

    It's Quercus robur, but the leaf has been in there with the developing tadpole from the beginning of july, so it has turned black by now.

    One of the tadpoles from the first batch just popped out the front legs. So this guy is what came out of the eggs on the photographs on page 1.

    Nice, just make sure your frogs aren't depleting their nutrients too quickly by laying that many eggs. I feed my tadpoles fish food and frozen bits of vegetables.

    Hi Manders, They are Dendrobates auratus (highland bronze). I keep them in a terrarium together with some of my highland Nepenthes. It seemed like an ideal way to combine hobbies :) Do you have some pictures of your frogs? Here is the father of the eggs sitting on a young eddy And the mother on her favourite bromeliad They don't mind the pitcher plants (or the cold at night). Only interaction I've seen so far is that they steal the occasional prey out of shallow pitchers (like jamban). I've got two more egg clutches developing right now and the first tadpole of those hatched yesterday. I am wondering if the tadpoles would survive in the pitchers but don't want to take the risk of killing them by throwing them in. What are you feeding your tadpoles?

    Are you keeping them together with carnivorous plants? I also have poison dart frogs and have made a photo series documenting the egg development of my first batch in detail. The eggs were laid beginning of july and the tadpoles are now developing legs. Sorry to hijack the post manders ;) 2-3 hours after fertilisation, 8-cell stadium: One egg already a bit further in early morula stadium, the cell in the middle is busy dividing 12-13 hours after fertilisation, blastula stadium: 2 days old, early gastrulation: 2,5 days old, gastrulation with yolk plug visible on the underside: 3 days old, end of gastrulation, formation of the primitive streak and primitive node: 4 days old, neurulation with formation of the neural groove: 6 days old, formation of the gills: 7 days old: 10 days old, lots of movement: They hatched at 15 days old
  12. Hello Do you have a picture of the raja?

    Fan in mini greenhouse

    Something that also helps against fungus in general is to place a tube containing some thymol crystals in there. When thymol is placed in a saturated environment it kills airborne spores of fungi and slows the growth of fungi by altering the hyphal walls. It also gives a pleasant herbal scent to the environment ;)

    Fertiliser choice...

    I use Akerne's Rain Mix for orchids and have found it to be very good both for the plants and for sphagnum. It seems to give the sphagnum a real boost as it really starts to boom after a fertilisation.

    Which Sarracenia Flava Variation Do You Have?

    I've got rubricorpora and cuprea, but I can only select one on the poll
