    Default Oxygen core dual pots

    I have heard about air core pots as seen by the pot on the far right of this picture, but has anyone used and had good results with what is called oxygen core dual pots? This is the poton the right which has two parts seen in the middle. I am trying to decide if these pots would workwell on say phal, oncs, and dens, Please advise?Name:  Pots - 1.jpg

    Net pot-in-plastic pot has been around for a long time, and allows a lot more air penetration into the medium from the outside than does a regular pot. The Air-Cone pot allows more air in from the center of the mass of medium - the part that would otherwise stay soppy in a regular pot.

    Another case of "many ways to skin the cat..."

    So then the Air-Cone allows the medium to dry more evenly rather than the outside drying quickly?

    I've been putting oncidium alliance plants in mesh pots for some time now but have been looking for something better. They dry out too fast on the outside while the middle remains very wet. What happens then is that no roots develop in the pot but because of the humidity surrounding it the plant grows superb aerial roots. Then when I can't water soon enough most of those die off. Never tried this two pot system but checked out a site that sells it. I know that I can purchase the 2" mesh pot for 40 cents and the clear for 35. The 4" can be bought for 75 cents each. So, about 1/3 of what they are asking. I see mini phals for sale all the time now that have a plastic cone that sits in the bottom of a plastic pot. The point of the cone is then inserted into a hole in a clear plastic pot where the plant is. I know this description is not very clear and hope I'm not stepping on any toes. I've been thinking of trying this with oncidium types.

    You can certainly create the same effect yourself with an inexpensive net pot inside an inexpensive plastic (or ceramic) pot. Turn the smallest net pot upside down inside it all and you have an "air cone . All of this should be available at your local hydroponics store or cost-conscious online retailer.

    So you are actually using three pots? Two mesh and one what ever your heart desires? I've been putting a small mesh pot over the drainage hole in clay pots for a while now. Can't get blocked that way.

    Hydroponics store is where I get them. About 1/3 the cost of a garden center. I know my post sounded very penny pincher but when you're talking dozens or even hundreds of plants it starts to make a difference. I'd rather spend the money on more plants.

    Are there advantages of one over the other? Perhaps some types orchids would do better with one and other types with the other? Yes???

    I don't think it's that simple, Monica.

    You need to take into account the needs of the plant, the potting medium, your growing conditions, and your watering habits. Also, keep in mind that what works for me might not work for you, and vice versa.

    For example, I like phalaenopsis in sphagnum in Air-Cone pots, or plastic pots with an inverted little net pot in the bottom.

    I have small vandaceous plants - those neo crosses, for example, in net pots of bark, sitting inside of another plastic pot.

    I have some oncidiums in baskets of sphagnum, and cattleya-types in baskets of bark. Now that I have moved them out of the greenhouse and will be growing them in my home, those also sit in plastic pots.

    I am NOT fond of plastic pots with the exception of the Net Pots which is the black pot on the right. However, Net Pots are very expensive in my opinion, so I use them mainly for reviving a dying orchid. Most of the time, I will use a clay pot.

    Lately, I'm finding that net pots work very well with Phals which love to have their roots exposed.

    Plastic pots (though much cheaper) tends to hold a lot of moisture, which quickly deteriorates the growing medium creating a stagnant environment where Anaerobic bacteria can exist. This stagnant environment is what KILLS most orchids.

    It's not so much the water because you can actually grow an orchid in plain water (not faucet water due to chloramines) as long as you keep the water clean, and submerge only the lower portion of the roots.
