    The grow room looks lovely and your orchids all look so healthy. My favorite thing I learned from you is the non wicking pebble top layer. I've been implementing it on all my semi hydro repots. It's working out nicely and I'm seeing success with the grow method. Now if only my cat would stop trying to take the pebbles off 😂 Does Muffin mess with your orchids? Would love to see how you keep muffin away 🙂

From what I can see it is a large collection which looks green, lush and healthy. Thank you for sharing your thoughts and answers to so many questions. This is helpful to me and how I look after my orchids. One question is: How are the Maxillaria doing when you used the three in different types of media?

    Hi, love your videos and learning a lot! I live in So California and it hardly rains, so rainwater is like gold. I know you checked the ph but what was the ppm on the rainwater?
    I usually let the first rainfall go then start collecting. Last year, the rainwater was 9 ppm, this year its 24 ppm! I think it would be ok to flush, but I’m thinking of getting the zero water pitcher since the rain is coming from the roof. Do you think it would be worth it? Thanks!

  • @LegumesEtFleurs
    @LegumesEtFleurs 3 года назад

    Very informative video. But too much to bear for my simple mind. Lol. Honestly, I only fertilized my orchids on the first year I got them (2015) then, nothing follows. Most are phals, only one Oncidium and another which I could not identify. I bought most of them at Ikea and the rest from the supermarket. They haven been flowering year after year, although not as many as when the first time I got them but I am happy with that. I bought two phals last Sunday at the garden center and hope they will do well. I repotted them the same day. Back in my home country (Philippines), my Mom only fertilizes with urine mixed with water and boy, they flower abundantly. I remember we had this denrobium-phal ( before moving house) attached to a Moringa tree that flowered abundantly almost through-out the year.

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад +2

      Optimal growth vs fine growth are very different things 🙂 Do what you're happy with, and I'll do what I'm happy with. I'm always striving for optimal growth and the best I can achieve in a set home environment with its own challenges, where watering with urea based Nitrogen would be an absolute no due to lower temperatures. Ammonia form Nitrogen is absorbed best at high temperatures, and can therefore burn roots in lower temperatures, you see. Organic media like bark has an inherent nutrient value, and in nature bird poop, rotting leaves, decomposing debris, all provides nutrients. Very different to a pot full of rocks, which is how I grow. People say to me, well I've been growing my orchid with no fertiliser and it does fine. I think thats great for them. But could it have done better with more optimal conditions? We will never know (except where I compared my mums no fertiliser to my fertiliser conditions 😆) but I suspect so. I'm not sure why it's too much to bear, but I'm sorry you didn't enjoy it! I try to provide very in depth information and detail, so maybe that isn't for everyone 🤷‍♀️ It's the type of content I enjoy making, maybe because I've spent so long in a research field, so it's just me I'm afraid. I try to take a fact based, research backed approach, and think my results speak for themselves in many cases 🙃

  • @ancientorchids
    @ancientorchids 3 года назад

    Great information Annabel! 🙏 ..Quick question, do you think that the fertilizer in the self watering reservoir will build in concentration with subsequent waterings? I wasn’t sure if I should use less because of that potential effect?

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад +1

      Thankyou! Well, the water/ nutrient mix will be almost used up between waterings, so that shouldn't be an issue if fertilising correctly- this is where regular flushing while you get used to the system can be useful, then re-topping up with your nutrients as a reset button 🙂

      Hi! If you want to see a more detailed fertiliser video for the active growing season , this one shows composition and adjustment for different orchid types.
      ruclips.net/video/p87-HcOuRTE/видео.html
      Larger, faster growing orchids require more nutrients when actively growing. As mentioned in this video, in summer I go from 300-500ppm depending on the orchid size and growth 🙃 You want to be looking at the individual element breakdown rather than overall ppm though.

    Very helpful, thank you for your info. I like your conservatory, so tidy! I have a question about salt buildup-apparently you don’t suffer it as much since you use rain water. Mine is pretty bad, using water from deep drilled private well. While my water test came back as very soft, My Leica and pumic get mineral buildup especially in 16 oz pots. I am considering using FloraKleen Hydroponic Clearing Solution, though I am quite nervous about whether it would harm the orchid roots. Any insight on this would be much appreciated. Thanks again for your videos. I really enjoyed watching them!

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад +1

      The first thing I would do is buy a TDS meter and test your water yourself- they are very cheap, under £10, and no calibration needed. If it comes back that your water is over 100ppm it isn't ideal, but there are ways around. Can you filter the water at all? ZeroWater filters remove all salts but are expensive, but even a standard filter will remove about half of the salts. Thats what I had to do for a few years while using tap water at the old place, tap and well water are definitely not ideal. Or can you install an RO system? You can pick basic ones up reasonably and run them off a tap adaptor. If you can't do any of those you will need to flush very regularly and be careful with fertiliser addition.

    I have a synthic question for you, if you don’t mind. We can not buy it in the US, nor can I find information about it. I would like to try it in my semi hydro. The way you use it and describe how it functions in your set up, I must wonder if it is some sort of microfiber product. IF my assumption is correct, I found microfiber mop heads at the Dollar Tree that are made with long microfiber ropes that are intermittently tied to keep the long strands together. This feature made it easy to cut the long ropes from the mop heads without the strands falling apart all over. Being a microfiber mop, the strands are water retentive and wicking. I am somewhat hesitant to add it to my own system, since I know so little about the actual make up of synthic. May I please have your thoughts?

    Annabel this was so helpful, thx for this video. One question that I would ask...when you grew under lights, did you have ideal or seasonal lighting recommendations? For instance, I'm running under lights at 14 hours per day. getting great growth, some freckles, some flowering...so I think I'm mostly dialed in, but would you have any recommendations to add? Thx!

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад +2

      No problem Normal! I'm glad if it was useful at all! One thing I would say is to vary day length with the LEDs so the orchids have some seasonal variation- so 10-12 hours winter, 14 hours summer etc. Orchids that originate near the equator with little seasonal variations won't need this, but orchids that bloom in spring/ winter etc will appreciate it!

    Hi Annabelle
    With regard to feeding extra silicone, do you still feed it to your species phalaenopsis and Cattleyas ?
    I feed Rain Mix and have been adding 1ml per 2 litres even though the water I use is filtered. Would you recommend that I stop feeding extra silicone to my species phalaenopsis and Cattleyas? Your answer would be appreciated. Thank you.

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад

      Hi Jackie! I don't feed any at the moment, I will probably resume in spring/ summer at a lower dose. This wasn't to say don't feed it, but more if you are feeding any extra elements to watch out for interaction with absorption and mobilisation of other nutrients. Phragmipedium are calcium lazy, they evolved in calcium abundant environments and therefore are probably less efficient at taking it up anyway, which is why they need high levels and are probably more sensitive to any nutrients that compete with it. I dont feel it is needed currently for the level of growth I get during winter, it is more important during development of new growths and spikes, and without any supplemental lighting I don't feel it is currently necessary as it was last winter in my old setup. I say if you are using it and feel you are getting benefits, continue, if not and you notice any leaf tip blackening of new growths that looks like calcium deficiency, maybe reassess.

    • @jackiehill6557
      @jackiehill6557 3 года назад

      Hi Annabelle
      Thanks you so much for your prompt reply. I haven’t noticed any blackening of the tips of leaves more like the leaves are sprinting in growth and the flower shoots are still growing. I have seen a remarkable difference in my phals and Cattleyas since feeding the Rain mix plus seaweed and silicone.
      I have also added some extra lighting as these dark winter days are a no no as far as I am concerned, so the conservatory is still like summer. What we do for our orchids eh?

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад

      No problem! I had to choose between heating and lighting this year, the conservatory gets lots of natural light but also needs lots of heat on overnight, so I decided for this year to see how I go without supplemental lighting. With the house move costs I dont need a giant Xmas electricity bill too right now 😆🤦‍♀️ But I definitely think Si is great for spring active growth for Phals, Vandas and Catts. Most of mine are flowering right now, they are growing too but I havent noticed any difference withdrawing Si for the winter.

I think it is important to talk in PPM as you did, rather than volume measurements, because a lot of people are using different formulations. 300 PPM of 13-3-15 is close enough in NPK to 300 PPM of other balanced feeds such as 20-10-20, 18-14-13 or 7-9-5 to call it even (the low K 13-1-1 being different). But, and forgive me for using imperial units, 1/2 tsp per gallon of 13-3-15 will yield 1/3 less NPK than 1/2 tsp per gallon of 20-10-20.
    Good talk. BTW, don't distract me with what you're saying by panning over to L. Elegans, I had to rewind. 😂 😉

      I agree, a real minefield, and when people ask me how much to fertilise with I always get a little tiny bit uncomfortable because it's really impossible to generalise. PPM of each individual nutrient is the best we have, but I vary it so much between summer and winter now, since I'm getting much less active growth not running all the lights over winter. It was lights or heat, and heat had to win 😆 But how much our orchids are even using and needing will vary between different growers! My small orchids definitely need less than the big, fast growing orchids, but in winter I can't be bothered to make them up seperate batches like I do in summer 😆 I should probably start doing that....

      @@TheOrchidRoom prepping different formulations is time consuming! I've got the plants split into groups so I try to water different groups on different days so I'm only mixing one formula on a given day. Sometimes they cross over, though, and it takes me forever to finish. (and that's just the ones in the house 🤣 )
      Although I'm currently trying out alternating feed and flush, versus 3 feed to 1 flush, to see if that makes any real difference. Roy Tokunaga says he only feeds every other month and he has some impressive plants. So far the black hair Dens seem to be growing well with the new regimen, produced the tallest, fattest canes so far. Next question is how will it affect the blooming. Obviously results will be different in organic media versus inorganic.

    Hi Annabel,
    This is probably a strange question, but you have mentioned many times that you rarely, if ever, need to flush your plants in semi-hydro, would it be possible to keep them in containers with no flushing holes?

      Yes, but when you do need to flush that would be an issue. I keep some houseplants like this but only a few orchids.

    Hi, does your pot topping prevent root desiccation? I have a few of my orchids in semi-hydro but I’m having real issues with dedication.

    • @TheOrchidRoom
      @TheOrchidRoom  3 года назад +1

      Hi! 🙂 Yes, in many cases for some types of orchids it can help 🙃 The non porous layer stops moisture being wicked up from the top layer of LECA, and traps it a bit so it isnt lost to the environment by evaporation- which will be faster the drier your environment. The non porous nature of the pebbles means they can't suck moisture from roots in the same way. They will still remain dry however, so for really sensitive rooted orchids they may not totally eliminate the issue, just help alleviate the harsh porous dessication issue. potting lower in the pot to allow a humidity shield and spraying down the top layer are other options that can help too.

      For more detail I did a repot and update series where I added the top layer on and explained the effects- this video has the most detail in the updates section ruclips.net/video/U5di5NnRYZ8/видео.html

    Are there any orchids that you don't grow in inorganic? I've had people say you can't put X, Y, Z into SH as it will kill them (typically fine rooted oncidiums)...
    Also, I've recently found those pesky snails in two oncs that I had repotted into SH & treated... so I'm not sure peroxide is a dead cert anymore (appreciate it breaks down over time, but it did still fizz when I used it)...
    Also, inorganic for non-orchids - might be beyond the scope of this channel, but would be interesting to hear if 1) you do this and 2) what with/successes 🙂

No, all of my orchids are in inorganic now, I made a video when I converted the last of the oncis and documenting the miltoniopsis in synthic / seramis 🙂 I have a few houseplants, but when I put out videos on them they bomb, I appreciate most of my sub base doesn't want to watch them but I keep persevering as I find them interesting too 😅😀 I snuck my maidenhair fern and syngonium frosted heart into this video, have done a video on the sansies before etc, violets coming soon but had the least interest on the video poll haha.

      I tried to grow schlumbergera cuttings in SH (before I had rain mix mind, so maybe they were missing some key nutrients) one rotted, but the other took - it just grew so much more slowly than the cuttings that went into soil.

      Old house under LEDs, 12-14 hours. New house- natural light, whatever the sun gives. Maybe 8 hours on the shortest days. Supplemented with LEDs for the darker shelves underneath, which are on a 10 hour timer.
