  1. Hi all. I've updated the Nepenthes guide with some new features. First, you can now filter the distribution chart to show only species which grow in a particular location. Hit the ‘Enable Region Control’ button and tick the boxes of the locations you’re interested in. You can choose multiple locations at once. Hit ‘Go’, and the chart will be filtered and sorted based on your chosen configuration. Lots of people requested this feature - thanks to everyone who made the suggestion. Second, the calculator can now be used to visualise the altitudinal distribution of a single species, as opposed to just hybrids. Several growers have told me they like using the calculator for this purpose, including @Jurkylius earlier in this thread. Rather than forcing a visualisation by entering N. lowii x N. lowii, for example, you can now just select one species and see it plotted on the chart. As always, feedback / suggestions are appreciated. Hope everyone finds these features useful.
  2. Hi everyone. As others have said, the HCP open day was fantastic - many great plants on display, and Matt was very welcoming to all the visitors. All my photos from the day are in a gallery on my website, in case anyone's interested: https://www.carnivorousplants.co.uk/blog/gallery-hampshire-carnivorous-plants-open-weekend/ Tom
  3. Thanks for all the positive feedback everyone, really glad other growers find the tool useful. Good question - originally, I intended for people to simply find a species in the list, and then consult the corresponding region of the temperature chart. My decision not to calculate an exact corresponding temperature bracket for each species' elevation was deliberate, since such numbers are only estimates and - as @manders rightly points out - plants don't always play by the rules. The hybrid calculator was added a few weeks later, along with some heavy caveats around data accuracy. I will happily add single-species calculations if enough people want them, however I'm reluctant to clutter the interface, which I feel is quite beginner-friendly as it stands. As a workaround, I suggest you simply select the same species for both parents (e.g. N. maxima x N. maxima). This will give you the same result. Cheers for sharing, and thanks to the creator of this chart. I saw this chart and several others like it before I began developing my tool. My goal was essentially to make a comprehensive, interactive, web-based version which can be updated continuously (and collaboratively, if other developers are keen to help ).
  4. I love the peristome on your N. Miranda. Stunning photos as always, thanks for sharing. What conditions do you grow your N. ventricosa x hamata hybrid in?
  5. Hi everyone. I've built an interactive guide to Nepenthes species: https://www.carnivorousplants.co.uk/resources/nepenthes-interactive-guide/ It includes a lowland/highland temperature chart, and a species list which can be sorted by altitudinal range or alphabetically, as required. I've also created a hybrid calculator, which can estimate the ideal conditions for a hybrid based on its parents' habitats. Many thanks to Rob Cantley of BE for suggesting this feature. I hope other growers find this useful. I'm keen to update and improve it based on feedback - several people have suggested a 'sort by country/geography' feature for the species list, which I'm currently working on. Any other ideas, please just shout. Cheers, Tom
  6. @Vince81 What an incredible setup - thanks so much for posting all these detailed photos and documenting your process. I'm particularly impressed with your watering system, and the use of LEDs in your lighting system. You've given me plenty of ideas for my next setup! My own terrarium is similar to the one Stu described - an AM2302 sensor firing temp & humidity data to a Raspberry Pi every minute, and switching my cooling fans on or off using Energenie mains sockets depending on the interior conditions. I documented it here. It was my first (serious) terrarium, so I didn't embark on automating watering or building a fogging system like yours. It's been very successful however (the Nepenthes seedlings are fast outgrowing it), so I'm considering an upgrade, or even building a larger one. When I do, I'll definitely be referring to your post. Please do post an update in the months to come, I'd be very interested to hear about your progress, and any challenges you encounter. Thanks again!
  7. Thanks Stu, really pleased to hear the terrarium tutorial has been useful I know some other growers who've adapted the instructions to create greenhouse controllers too, which is pretty cool. Got some new resources in the pipeline, but I'll continue to update the Nep charts and Sarracenia distribution map based on feedback.
  8. @Richard Bunn Thanks Richard, much appreciated. If you have any ideas for similar tools you'd like to see, do let me know - the hybrid calculator (scroll to the end of the Nepenthes guide) was originally Rob Cantley's idea! @linuxman Cheers linuxman. Are you referring to the yellow I used for S. flava on the map? If so, that's easy to change. I tried to go for high-contrast colours to ensure colour-blind visitors could still use the map, but I agree that some colours aren't quite perfect.
  9. Huge congrats to Matt, very well deserved - photos looked incredible. https://www.instagram.com/hampshirecarnivorousplants/
  10. I've built an interactive Sarracenia map, and thought it might be of interest to other growers. Each species is plotted with county-level distribution data and subspecies info, where applicable - just hover your mouse over the map (or touch if you're on a phone). The map is part of my Sarracenia growing guide, but you can jump straight to the map using this link: https://www.carnivorousplants.co.uk/resources/how-to-grow-pitcher-plants/#map Hopefully it's useful to fellow forum members. More information on the source data is available in the accompanying blog post here. If you've got questions or suggestions for improvements, I'd like to hear them. Thanks!
  11. Hi pmatil. I've heard stories of the humidity sensitivity of DHT sensors deteriorating in these conditions - luckily for me, it's the temperature I'm mostly interested in. When it's too hot, cooling switches on, simple as that! Humidity isn't hard to maintain in my terrarium, and realistically it can't ever get too humid for Nepenthes. I've got an internal circulation fan to help encourage air movement and prevent mould. Still, I'd be interested to hear what solution you end up using for your humidity controller. Also, what heating system are you using? I'm thinking of creating a similar terrarium for lowland plants one day (I'd like to grow an N.bicalcarata), and have been looking into heating mats to raise the temperature. Thanks for the comment!
  12. Hi all, Long-time lurker, first-time poster. I’d like to share a guide I’ve just written: it explains how to build a low-cost terrarium controller using a Raspberry Pi 3. As you’ll see from the photos, this is based on my experience keeping a terrarium for young Nepenthes. The system does a great job of maintaining a steady daytime temperature - I get half a degree of fluctuation around my chosen target of 28.5 degrees C, and humidity is always above 85%. The system also intelligently controls my lighting, cooling fans, and circulation fan. Finally, all data is plotted to a cloud service allowing me to monitor conditions remotely. You can read the guide here: https://www.carnivorousplants.co.uk/resources/raspberry-pi-terrarium-controller/ My terrarium is constructed from an Exo Terra - I’ve replaced the screen top with a pane of glass to retain humidity, and fitted a T5 fluorescent lighting unit to the top. The bulbs provide all the heat I need, so no separate heating pad is required. Some small PC fans are positioned to cool the lighting fixture, but these only activate once the interior temperature has reached my daytime target. An interior circulation fan runs during the day to prevent the glass steaming up. The night time temperatures in my flat aren’t cool enough to grow true highland species (it’s generally about 21 degrees C), so I’m instead growing tolerant intermediates and hybrids - N. sanguinea, N. maxima, N. ampullaria x ventricosa, and N. veitchii x platychila. They all seem to love it - the photos in the article are quite out-of-date, and all are pitchering profusely. I’m also trying my luck with N. spectabilis x ventricosa - I've heard that this plant might not like warm nights in the long run, but for now, it seems to be growing rapidly like the others. Anyway, I hope this guide is useful to some other growers. I’m happy to answer questions if anyone’s thinking of building something similar, and I’d be keen to hear other people’s experiences with automating terrariums. Tom
