    Hello RTB, Yes, I do fertilize occasionally (every month or two) with a weak solution of 1/4 tea spoon of Urea Free Orchid Fertilizer per gallon of Reverse Osmosis water. I also use a balanced trace element supplement (1.0 ml of the liquid stuff sold for planted fish aquariums added to the fertilizer water). For a while I was fertilizing more often (bi weekly to monthly) but it was affecting several of the plants negatively. N. ramispina did not like fertilizing at all and quit pitchering now it is back to making a 4" pitcher but it would probably be making even larger pitchers by now had I not fertilized it. I feed the active pitchers every month or so with a fresh frozen (and defrosted) cricket and insect feeding is what really seems to make the growing difference (of course along with good light, pure water and high humidity) but fertilizing is fine if not done in excess.

    I use power compact flourescents over the highland tank that the above plants are from. There's aproximately 300 watts of PC lights over the highland tank. The color temp of these lights are 6500K and 9250K (or something like that) as I was originally going to be using them for a saltwater reef tank but things changed. When I replace them I will switch to 5500K and 6500K to come closer to tropical sunlight.

    Hope that helps! [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    Hmm, ok. I'm having some trouble with my light setup caus it gets too hot at summer. Totally I got 348W over my highlanders. Earlier I only had around 60W. The problem is that I can't give it the air movement that's required I think. Gotta do something about that. Can I cool the plants down with ice on the hottest days? I can see that my rajah is suffering in the heat so I gotta do something quickly. I don't wanna cut down on the light caus the plants aint happy without my additional 300W either. I will take a look at some small fans that I could use tomorrow but I fear that the humidity will be effected if I use a fan. I'm relying on water at the bottom of my terrarium for humidity. I don't own a hydrometer either, he maybe I should get one tomorrow as well if I find any. The rest of my plants are happy with some cool water sprayed at them but the rajah is not.

    Yeah well, good night, gotta go.

    Best regards

    Robin

    Robin,

    A hydrometer/hygrometer is not a necessary tool for the culitivation of Nepenthes. Most meters (unless you want to spend 50$ and upwards for a good one) are not accurate. The best indicator of your conditions (humidity) are the plants. If they are happy you can assume that humidity must be decent and/or they are hardened off to the climate. You could cool them with ice if you prefer. It would work in the day for a little cooling but not by much. Maybe place a small battery-powered fan in back of it? It would make a small evaporative effect with it blowing the air from behind the ice and maybe cool the enclosure down a few degrees if you are lucky.

    Hi Josh,

    very nice plants you grow!

    BTW are you sure your N. hamata isn't a complex hybrid? Especially the shape of the lower part of the peristome differs slightly from what I would expect from a pure N. hamata. The shape of the peristome resembles those of some clones of N. tentaculata. Also the the biggest pitcher in front is slightly more bulbous than I would expect. The size of your plant exceeds the size Turnbull and Middleton mentioned in their type description considerably. (The picture of the lower pitchers in Flora Malesiana shows these differences quite well.)

    Of course my impression might be due to the bigger variabilty of clones I don't know of, your growing conditions or the angle the pictures were taken.

    Cheers

    Joachim

    I will say I do not know how you would grow the highlanders without the airflow (fan) and ultrasonic humidifier as when I started with highlanders I did not have these and my plants did not do as well as they are doing now. I get fans from 1" to 4" in size from Radio Shack they call them "PC fans" these can be a bit pricey from $5 to $20 each. Wal mart has a 7" diameter Oscilating fan for about $8 but it takes up a lot of space for a small terrarium and may be too powerful for a small space.

    If you have a Wal Mart near you, they sell a digital battery operated hygrometer/thermometer combo for about $15 (in the hardware dept with the rain guages and other thermometers). They may not be scientifically accurate but they will obviously be better than nothing at all and at least give you an idea of what your temperatures and humidity levels are. and how they vary over a 24 hour period (highs and lows) I use them in all my growing chambers and find them plenty good enough.

    Joachim, I do not know exactly if my hamata is a complex hybrid or not. It is from Tony Parobek so it is likely the plant is from either Rob or Andreas. Do you know anything out their clones of hamata like you did the clipeata? I know that my plant is already as large/larger than in Flora Malesiana and the latest pitcher was even bigger than the one shows in the photo (front). I'm not complaining though!

    You're very observant! For the peristome shot I did indeed use a weird camera angle and it came out looking far squarer than if I would have taken the photo head on. I folded up the tripod and held it over my shoulder like a bazooka rifle and aimed the camera down into the peristome (using the folding ccd screen to see what I was doing).

    To date all my N. hamata have come from Malesiana. They have at least 3 or 4 clones that I can distinguish.

    I think the slighly odd shape is from the camera angle. Also appears to me, to be in lower pitcher mode still, which has a narrower pitcher opening.

    Is that a Nepenthes in your pocket or you just happy to see me?
