    For growing which types of orchids?

    You know different orchids require varying amounts of light. I personally have trouble providing enough light at home for catts. But is enough for my oncidiums except maybe the Tolumnia. All my artificial lighting is fluorescent. And my windows don't get as much light as I would like due to building and tree shading. I have as many hanging from hooks in the ceiling in front of my 3 windows too. I have 14 hooks with room for maybe 3 more.

    I am not completely knowledgeable about all the light sources, but I am of the understanding that high pressure sodium are best for catts and other high light orchids but coming with lots of heat to manage.

    for growing Catts. I was thinking about fluorescent light. So far I found source that sells bulbs of different length and 4' long (optimum for me)provide about 600 - 800 fc, so to rich 2000 - 3000 fc I was thinking I need at least 4 bulbs if it works as simple as simple arithmetic.
    Im not big fan of high pressure metal bulbs due to as you said it generates too much heat.

    I am under 8- 4' tubes and I am able to grow phals under it without damaging them.

    The short plants are maybe 24 inches below. Taller are only 4 inches away. The taller ones are oncidium alliance and dendrobiums.

    Hi Chemist

    You will need to see how the plants respond in your east window. It may be fine, or you may need to supplement with artificial light.

    The plants are healthy, so that is good. If the plants meet your expectations, it seems like the deal was worth it. I only mentioned that they were not blooming size yet because I thought the seller mis-represented the age a bit. To me, near blooming size suggests that you will have blooms within a year. I like the strategy of buying smaller plants and raising them to blooming size; that is what I do with most of mine.

    As you say to repot catts when there are new root grow.. I'm still in doubts even if mine has new roots growing (but I don't know HOW MUCH them have to be grown to repot). Wait. I'll put a pic on those roots.
    Anyways, in which pots are better to grow - clay or plastic? Currently they both are in plastic pots but I'm in a doubt which one to chose. And how to know when is needed to repot Catts, the same like with phals and paphs when the pot becomes too small and too full of roots or like other orchs cambria, miltonia ecc. when the potting media starts to break down so every year? Sorry if this question has already been I forgot to check.
    Are those considered ENOUGH grown roots for repoting my cattleya or I should wait?

    I just started trying orchiata bark this year with some of my cattleyas and I found that it stays wet longer than regular fir bark and it seems to dry more evenly as well. I've had a hard time adjusting to it however, because to me, it looks dry before it really is, so i have gone back to putting bamboo skewers in my pots (the kind used for shish kebab) and when you think you need to water, you pull the stick out and see how wet it is. Also, a lot of people said the plants look healthy, but they look pretty shriveled to me. I would soak them (each in a separate container) for an hour or so each day for about 2 or 3 days. They should plump up a bit again if they have good root systems. If they don't, I would gently remove them from their pots and take a look at the roots and medium. If the roots are bad, you may have to do emergency repotting and try not to damage any of the growing root tips. If you see a lot of root tips that are black or if you have dark watery-looking areas on the root but the rest of the root looks fine, you need to spray with a fungicide for pythium/phytopthora. Anyway, you can always post photos of the roots if you need help in that area. As for lights, I've been growing cattleyas under 4 4' plant and aquarium bulbs as well as t5 high output flourescent tubes (4 bulb and 6 bulb fixtures) they put out some heat, but if you have a bit of air movement, they should be fine as long as you can keep up the humidity. since you have an east facing window, you could probably get away with hanging a 4 foot fixture (2bulb regular flourescent) shop light over the windowsill and that with the sun would probably give you enough light.

    Missana,
    when you say soak them, do you mean soak the pot not the PBs? If to soak pot for an hour for 3 days, don't you think orchiata bark will be too wet for roots, especially now when average daytime temperature not higher than 75F (22C)?

    Catt Mandu,
    do you grow any of your catts mounted? if so any advise on the mount material and watering schedule?

    I received yesterday cattlianthe chocolate drop ‘volcano queen’ (c. guttata x gur. Aurantiaca). Seller send it bare-roots.

    As you can see there are not that many roots... What the action? I tried to pot it in bark i have but it looks to coarse for those little tiny roots. On seller's picture this plant was potted in 4" pot, i dont think it needs such a big pot for amount of roots it has, am I right?

    Catt Mandu, what size of cork pieces you would use to plant this guy? I have some cork round flask stand at work so i can break it into small pieces

    When I grow Cattleyas with corks, I am using wine corks, either whole or sometimes cut in half for seedling plants. Here is an example of one of my plants growing in whole wine corks:

    Although I do have some mounted plants, I do not have any mounted Cattleyas. My understanding is that some Cattleya species (like c. Aclandiae) do prefer mounts, but most of the hybrids seem to do well in pots.

    I don't have a Cattlianthe Chocolate Drop, but I do have another Cattlianthe with Chocolate Drop as a parent. I would recommend about a 4-inch clay pot, you could grow with coarse bark, or bark/charcoal mix, or use wine corks cut in half. That looks like a healthy seedling - roots seem fine. At blooming size, pseudobulbs + leaves will be 12 to 18 inches tall, so it has some growing to do. That is a good Cattlianthe to start with, it will grow quickly, bloom twice a year when mature and is fragrant.
