  1. I think there are some newer generation RBG whites, but not sure... on the subject of spectra, here is a very good paper http://arxiv.org/ftp/arxiv/papers/1406/1406.3016.pdf
  2. JM, Its the "Philips GreenPower LED Flowering Lamp" It comes in three variants (at least here in the states) Mine (and Carl's) is the White/Far Red/ Deep Red version. It was designed as a supplimental light to aid in flowering for greenhouse use. It was not designed as a stand alone plant light (per a conversation with vendor) Fred, I have a rack with 5000k 92 CRI lighting, I'll endeavor to move it there for some pics
  3. Fred, Yes, to look at the light its very pleasing to the eye. I would guess the CRI is relatively high. The light reminds you of the older plant gro fluorescents that had a pinkish tint. I suspect that much of the Red is beyond normal human perception. JM, I tried a ping with it and the colour wasnt unusual but the growth rate was very fast. Carl has the same light with a heliamphora and its color wasnt "unusual". I think he is about to try a ceph and see if he gets the same response. The light itself is rather small, its not anything you can illuminate more than a specimen plant with. one month later some observations and caveats.... The camera used to take the ping images seemed overly sensitive to the red leds, The substrate and dead plant material looked "normal" to the eye, not pink like in the images The Cephalotus is a "Hummer's Giant" but a clone that turns very dark/blackish under normal lighting. I believe it is from one of the plants Pokie used in her "which one is it?" threads I dont know if its the extra red, the lack of blue, or the increased ratio of red to blue... nor do I know if it would make every Cephalotus that color. But after seeing what it did to this one, the light has found its home :-) I have the light almost on top of the ceph btw, but it was some distance from the ping.

  4. Cephalotus grown using LED light with white, deep red, and far red LEDs
  5. edit: add caveat I should add that Turface is actually a brand name with several products... some have dyes in them, etc. The one I actually buy is their "All Sport" product sold in the states at John Deere Landscaping supply stores
  6. In the states, Aquatic plant soil and Turface are identical... just packaged and sold for different uses. Turface is much cheaper to buy... its all I have used for several years now. 13USD for a 18kg bag Vs. 25USD for a 4.5kg. The APS with Zeolite added (Pond Care Brand) has so little zeolite there is no benefit, just marketing. As others have said, what will work best for you is determined by your watering habits, your airflow, etc etc. No one right answer, that being said.... after years of use now, I still use APS(Turface) /Sphag/Perlite Av (Butch)
  7. H. minor var. pilosa question.... Mine is still very small, recovery has been a long road back. I now have several mature pitchers about an inch and half tall. Color and shape are good, but none are showing any hirsute tendencies yet.... starting to worry. I know in the official description it mentions the hair is only found on the upper 2/3rd of the pitcher (iirc, I would need to verify that statement so don't quote me) So wondering if the lack of hair at this early stage is normal or if I do have an issue with my plant or my conditions. Would like hear from those that have experience with this species. thanks in advance Av
  8. Sadness, but knowing your abilities Fran├žois.... not too worried long term. Wish I was close enough to be of some real assistance. Butch
  9. (going by personal observations) If you cut it at this stage the plant will likely just send up a replacement. If you wait till the first flower opens to trim it, a replacment is much less likely. The flowers are very elegant and I have never had issue with flowering killing the plant.... If this is your first, I'd say let it flower... Be prepared for a tall stalk with 3 to 5 flowers (varies) eventually. My Heliampahora bloom twice a year and can be self pollinated easily enough.... There is some "art" to the process. But once you have that "ah-ha" moment, it becomes very easy. It takes about three months for the fruit to ripen. Congrats and good luck, tuning fork does make the process much easier IMHO. Of course YMMV Av
  10. H. pulcella H. parva H. elongata any others? What about H minor var. pilosa? I have an old clone of H. ionasii that does, but I believe it to actually be H. ionasii x elongata Av
  11. Geeze Bill, you have no mercy ;) That is my current "holy grail" quest heli..... Very, very nice mate Carl, looks like a Polytrichum moss of some flavor.... Butch
  12. David, U nut ;) Hopefully determine the "shelf life" of heli pollen and the effectiveness of common storage techniques....., Warren is already hinting at a CPN article Hmmmm, come to think of it.... you would make an excellent co-author old friend ;)
  13. Heliamphora folliculata pollen tubes (please forgive the poor technique, Im learning) small youtube video showing the length of one of the tubes thanks for looking, Av
  14. I tried the commonly available harzianum strain available here in the states (T. harzianum T-22) but had much better success with Ampacbiotech.com's blend of T. atroviride and T. virens ( I think its T. virens, but would need to verify) When you apply it dont apply it immediately after fertilizing or applying a B. subtilis product. Peer reviewed research shows that trichoderma is less aggressive toward phytopathogens in a nutrient rich enviroment. Likewise some strains of B. subtilis have been shown to be antagonistic toward Trichoderma I like using ampac's "flowable" formula as a monthly drench.... I mix one tsp per gallon of water and drench until it flows out the bottom of the pot. Peer reviewed research has shown the benefits are systemic. Sometimes I also mist the plant with the trichoderma. I then catch the run off and use that on my less expensive outside plants peer reviewed link Peer reviewed link ampacbiotech.com
  15. Personally, I am a big fan of Trichoderma atroviride.... Fungal issues have dropped to near zero since I started a monthly application of it.... but do your own research. Some heli clones dont seem to like the light near as intense as others. If these clones are exposed to very intense lighting and have water droplets on them... damage similar to what you have may be seen. HTH's Av
  16. Without knowing the condition specifics.... If you're misting it, stop immediately Increase light intensity, I would also be curious as to the spectral performance of your lighting.... have you got a spectrometer? Increase airflow (volume not velocity) Repot with a nice open substrate Use Trichoderma HTH's Av
  17. (Wistuba clone) The colour, waxy appearance and interesting nectarioles of this clone make for a beautiful plant IMHO. My apologies, in the clump shot the plant is a little rough looking from being repotted a week or so ago... Thanks for looking, Av
  18. hehehe I had edited that statement out before i saw your reply... my bad :) but would it?... cool and damp would seem to be an ideal enviroment for fungus I know you do, that wasnt pointed at you mate.... like I said, Ive been down that road and tend to be a bit gun shy. sorry about the price there, here Its relatively cheap.... you might want to try ampacbiotech.com, I believe they can ship to the UK. ( I inquired once when checking on the possibility of sending you a little sample from my stash)
  19. Mobile, The strains I use were isolated from the boreal region of Alaska, so I think that would meet your first concern. But it is not T-22, it is a cocktail of patented T. atrovirde and T. virens strains.... I will admit to blending in some other strains on occasion just for good measure. One commonly available product in the states is a T-22 variant, and I was less then impressed with it. But I think its main issue was the poor spore count the product has.... so it's mostly inert fillers. My personal experience is just that... I use to have the same problems that many have with cephs and helis and now I don't. Alone, I would not consider that of any value.... but that experience added with the photographic evidence and the body of research papers makes it the icing on the cake. I have read more papers on Trichoderma than i care to count. To this day I have yet to read a single study saying it wasnt effective... in fact, it has the ability to tailor its attack based on the phytopathogen it encoutners. I will not say its a magic bullet that will cure all ills, far from it. But I no longer have issues I had before with plants grown under the same conditions. I dont care if people use it or not, its up to them... Im not getting pulled into an argument on trichoderma.... been down that road too many times. (not you mate :) ) Just trying to add my experiences as a veteran heli/ceph grower to the conversation.
  20. I don't really understand the cp or not cp argument with Trichoderma. Photomicrography (from several major academic sources) has shown it coiling around the phytopathogen, attacking and degrading the cell walls. Since the Trichoderma is attacking the phytopathogen directly, this beneficial action would seem to be irrelevant of the plant being a cp or not. Now Trichoderma does benefit the plant in other ways, and these additional benefits may or may not qualify to the cp/non cp debate.... But in any case.... FWIW I no longer have issues with this disease and I have some experience with Helis peer reviewed research Peer reviewed research (just two of many papers on the subject) For me, its hard to deny the photographic evidence and overwhelming peer reviewed research that is backed up with my own personal experience... Of course your milage may vary, and there are indeed many strains of trich, some more effective then others for any given application. HTH's Av
  21. Too bulky to order online... shipping would be a killer Try your local hardware stores, Lowe's occasionally carries the Schultz brand APS... HTH's, Av
