Hello everyone, As somebody who would like to take on the fascinating world of Terraria for keeping carnivorous plants, I lurked the forums for a while to absorb as much as I could from such a great knowledge base. In terms of lighting, while there are definitely great products out there which deliver impressive PPFD numbers, for me, it is important to keep my hobby sustainable and as cheap as I can. I had so many questions about cheap lighting for my plants: are they garbage, could I actually grow with them...? Being a scientist by profession, I thought I would like to try and perform some experiments to answer some of these questions. In the video I compare the results of growing lentils in a sunny window vs. under 80W of artificial light to see how they stack up. I used a photoperiod of 12hrs. 80W will cost you about a fiver per month to run in the UK (national average). The lights were: 100W Citizen CLU048 3500K (£13.24 on eBay) driven at 50W using 1500mah driver (£5.24 AliExpress) and 30W YXO Yuxinou driverless Blurple COB running BridgeLux chips (£1.66 on AliExpress, lol) They were cobbled together using some thermal paste (£0.64 AliExpress) and scrap CPU heatsinks. So all in, around £20. Interesting results indeed. I'm also currently performing comparisons between the Citizen and an equally powered AliExpress blurple and some "300W" led light panel that a company has sent me as a tester. Will report those results too if anyone finds them of interest. Cheers, MTech
T8 & Power led
Miguel Angel Medina posted a topic in General Carnivorous Plant DiscussionWhat do you think about its application in pinguiculas: t8 & power led high power ....
DC Carnivores posted a topic in Terraria - Cultivation & EquipmentHi all, I’m looking for a good led illumination for my terrarium, the measures are 100x45x35 cm (140 liters). I would be interested to know which brands, which colors and wattage; will be placed various species of plants, nepenthes, cephalotus, drosera but also sarracenia seedlings. The terrarium will be only used as winter shelter or for debilitated plants, but if I see that the light is good, I could keep tropical plants all year. I saw a solution like this: http://www.hydroponics.eu/sonlight-apollo-led-4-130w~10022.html but I would prefer lower cost and a lower wattage, 130 Watt for that little terrarium seem too many imho Thank you -Dan
Cold, dark and not fun for plants.
Little-Bacchus posted a blog entry in BacchanaliaAs I type this hail is battering at the window, Well it has been a little while since I added a page to my blog. My little plants are still doing well and feeding like mad but due to the low light levels growth has all but stopped. Each plant now has about eight leaves and two that have yet to unfurl. All in all the plants look like they have gone into a slow growth phase. I now see the importance of light for them, not that I don't know that all plants need light my ficus is also slumbering waiting for longer days but it does go to show that without light feeding of Drosera is little close to pointless. On the note of feeding one of my little seedlings has caught its first big prey, a fungus gnat. It is also the first time I have seen all of the tentacles come into contact with a trapped insect and the curl to engulf it. The leaf in question is only approximately two millimeters wide by four long and I am still having to observe any action with a magnifying lens. The dew on the seedlings comes and goes, some days it is heavy and visible with the naked eye, others it is only a very thin film over the glands only discernible with magnification. This has also let me see that the glands on the outer tentacles are on the side rather than on the top as in the ones closer to the middle of the leaf, I do not know if this is a trait of Drosera capensis and I will have to look into this. I have seen something the same in pygmy Drosera and labeled as 'snap tentacles' although the ones on the D. capensis do not show any faster movement than their counterparts. I wait like the plants for longer days so I can again see the rate of growth...
FiloRp posted a topic in PinguiculaHi everyone, I bought two weeks ago a Ping Red Light from Gert (araflora) during the italian CP meeting. Now I'm keeping it with pitcher plants but it's becaming quite cold and I still do not know if it can stay outside during winter or if I should keep it "inside" with cephalotus and drosera regia. Thank you
Hello, this is my first post in this forum, and one of the main reasons I join rather than just stalk all your old answers. I've some experience with carnivorous plants and plants in general, also in bonsai, but I wouldn't go so far as to say that I actually know what I'm doing. And I've none whatsoever with terrariums and artificial lighting. I recently got re-interested in carnivorous plants strongly, and the only way to get plants where I live, with a few exceptions, is by ordering them online. Like living plants have hard regulations and even quarantines times here, I ordered seeds online. So, to the point. I builded a "terrarium" to grow the seeds now, and in the future to keep some of the plants I'll grow there. I used a space that was originally build for a TV, but like I haven't had a TV for over 4 years I thought about giving this empty space a better use. Here is the thing It's very simple, enough to keep the humidity and heat inside I think Here is the thing that is worrying me. It's about 65cm tall, and worried about the amount of light. Right now I've this LED panelin it. This is how it looks: (it's no finished yet) I put some aluminum foil in the walls, and I also redirected the LED spot lights outside to the inside. It doesn't give much extra light, but you can see the plants inside better. So, this is my question, is this enough light to germinate seeds? should I lower the panel? get another one? another source of light maybe? Should I forget about this wretched thing and just germinate them outside? The seeds which I plant to germinate there are the following ones: - Sarracenia seeds (already in the fridge) After their first year or so I'm going to put them outside. - Darlingtonia seeds (also in the fridge) With this ones I wanted to try some inside, and some outside after they grow a bit, I'm worried about the high temperatures in summer. - Heliamphora nutans. Now this ones are important to me. This ones are the ones which I more care about. I only have five of them (in the mail right now) and are really hard to find. I almost bought some plants from wistuba but I didn't have the courage, nor the money to import living plants. Also, this ones are really important because they are the main plant that I think to grow in this "terrarium" once the seedling stage is over. So any advice here would be very very welcome. - Cephalotus seeds (also in the mail and really hard to find) I also only have 5 of them, and cant afford to lose them. -And a bunch of nepenthes seeds (highland and lowland). Now, this maybe was unwise, but I found a seller in eBay who sold me 400 seeds for like 5 dollars, and I couldn't resist. I really don't worry about this ones, I've so many. Nonetheless, I want to give them the best possibly chances of growing. Please, pardon the long post, and any mistake in my english, I had the luck of studying english in London for about a month, but I don't think it was near enough.
How much is too much?
Little-Bacchus posted a topic in DroseraThere is a lot about light and heat for are beloved plants but how much is too much. As some will know we are in something of good weather for the UK but my garden is hitting 27oC and light levels are through the roof. It is at a point that I have had to shade some of my more shade loving seedlings, Digitalis and such. I have my one seedling sunning in the garden and a set of seed and some look like they may be starting to germinate (when viewed at 400X magnification) all covered to stop them drying out but am I at risk of cooking them?
paradisaea posted a topic in General Carnivorous Plant DiscussionHi :) I have tried searching for info on here that might help me out but to little avail. Perhaps if I have missed something glaringly obvious, somebody may point me in the direction of an existing thread that I can read though, but in the meantime, here goes! I got back into keeping carnivorous plants just over a year ago and now that I have the time and space to do a better job of it, it's gone a little way beyond a few plants kept on a windowsill. I have a cold frame greenhouse that I keep most of my plants in year round, with the exception of some of the more delicate ones I have obtained recently that I will treat accordingly when the time comes. Anyway, amongst those that I have out there are some yearling seedlings- both vft's and cobra lilies. They were out over winter and survived just fine but they are so very slow growing, I am wondering if they may do better if I were to bring them inside and put them under my T5 grow light? I just bought it for other plants but I would like to use it for my carnivores if it will be of benefit to them. I also have a bunch of sarras, some more Darlingtonia and a new lot of giant vft seeds that I sowed a little while back which are now beginning to show (well, not the vft's, it's a little soon for them yet I think). Would they be happier in more stable temperature/light conditions do you think? Everything else that has been kept outside in the little greenhouse is doing really well but I am still very new to growing from seed so if anyone has any advice regarding what I could do to give these seeds/seedlings a stronger start, that would be great :) For information's sake, the seedlings are all about 1.5cm across, the darlingtonia each have a bout 3-5 little tiny traps and the vft's a few more and the new lot of sarra/darlingtonia seeds that have germinated started showing maybe a week or two ago. They are all in appropriate carnivorous plant mix compost with no moss at this stage. Also, I have one small nepenthes hybrid (no idea what... it was a garden centre gift from someone) that was in the cold frame but I have since brought it inside after reading more about their care. It gets wonderfully warm and humid on sunny days but I fear it might get a bit too cold for it at night out there. I don't have many bright windowsills in my house that are not in direct sunlight. Where would you suggest I keep this plant that it may thrive? I have a modified shelf in the cold frame that blocks direct sunlight but is still bright but I just don't know if it's a good idea to put it back outside at the moment! Any help would be much appreciated. Thank you!
How are my plants doing?
insectivoroushouseplants posted a topic in NepenthesHey guys, wondering if my nepenthes are doing alright. The leaves are getting some red coloration but i think thats just intense light, not dying plants. There's also some brown spots on some leaves. The reason I asked is because i just recently moved them from outside to under 4 24w 6500k compact florescents. The reddening might also be from when they were outside. ^^^ N. ventricosa with the most reddening. The closest leaf is probably sunburn from when i first got him. close up N. alata x ventricosa. this guy has more browning but I believe it was due to not enough water when i was vacationing. They're young and otherwise look healthy so im not terribly worried. The N. alata wont pitcher for me (shipped to me in the spring) but these are my first ones, im not expecting giant pitchers right away. Any comments on my set up or plants would be great
