    Default Compact zygopetalum and other questions

    I love fragrant orchids which is why I go for cattleyas, but I think zygopetalum are really pretty as well.
    It's kind of hard to find some of the info about exactly how big they get. I saw one at a show about 2 feet high which is too big for under lights.

    so: to anyone who grows these, I have a few questions:

    Are there any compact species, hybrids, inter generics a foot to a foot and a half tall (including the pot)?

    Are there any that are warmth tolerant ?

    Are the roots thin like oncidium, intermediate like cattleya, or thick like phalaenopsis? ( I have a really hard time with fine rooted orchids for some reason)

    Most everything I read about zygos is that they are cool growers, and since I grow under lights in a house, I can't get the temperatures very low in the summer and it's a possibility that I simply cannot grow these because of size and temperature, but if there are any zygo experts who may be able to give me some ideas, I would really appreciate it.

    My zygo seems happy growing under my lights with summer temps getting up into the mid-80's in this location in the house. It is now growing its second new pb of the season so I expect a flower cycle soon. 1st new pb already bloomed.

    I would say the roots are intermediate.

    I think I would call Zygos generally cool-intermediate for temps. As long as night temps are rarely uncomfortably warm for humans they won't be too unhappy.

    Look for Propetalum hybrids (Zygopetalum x Promenaea). Many Promenaea species are well under 8" so the hybrids are among the most compact for Zygo types.

    i have a Bollopetalum Midnight Blue 'Cardinal's Roost' that is smaller than a typical zygopetalum. you can also find it listed as Zygotoria, so apparently at some point one of the parents was reclassified. the leaves are still about 18" tall. i have mine in a 5" pot of sphagnum moss with some treefern fiber mixed in. it likes to be damp, but will handle occasional missed waterings. actually quite a sturdy plant that can handle some abuse. it survived a couple years of too little light, and a spot of being left in full sun. i now have it growing and flowering. they smell great. blooms multiple times a year on young new growths. and can give 3 spikes a bulb if really happy. bright light, i have mine growing among cattleyas and himalayan vandas. as to the roots, i have to admit, none are showing on my plant. i seem to recall they seemed smallish, like cattleya, but fuzzy, and hard to distinguish from the moss i grow it in. i've just dug around a bit, and cannot find roots really, but i know it has them, it has a tight grip on the wad of moss.

    Thank you everyone for your replies
    Terp: how many bulbs (I think you grow under t5s) are in your fixtures that this plant is under and how far away is it from the bulbs?
    Thanks.

    My zygo's leaf closest to the light is 9 inches below and 22 inches to the bark. It grows well where it is. It is on its second new growth of the season. I expect a spike soon as they bloom early in the growth cycle.

    I am under an 8 lamp fixture with 4 full spectrum and 4 red lamps.

    Thank you so much for the info terp! I had a sick cattleya bloom a foot and a half away from the lights (totally unexpected) so I think I've had my orchids waaaay too close to the bulbs. Always battling heat and dryness.
    Oh yeah - I also noticed that you have those white clip on fans- I think they are the two speed kind that come with the clip and a base for solid surfaces... You said you run those 24/7 right? They look like they blow directly on your plants from your photos in another post and that seems like it would be too drying to me, but do you still run them? That often and that close?

    Yup.
    I do mist daily at least once and under the gravel is water. I do water every other day partly due to the fans and partly the semi-arid dry air. I do try to blow the air above their heads and not down at the pots and yes, 24/7/365. 2 speed as you say and I run on high.

    In my living room, I have 13 hooks in the ceiling around the windows and have orchids hanging there as well as on tables, speakers, stereo cabinet, kitchen widow sill and 3 more hooks above that window too. I run a box fan in the LR 24/7/365 too.

    Are you under T5's too? How many?
