    Default Comparing catts in bark and S/H

    I jumped in to orchids in a big way last fall, ordering 100 mixed species for a fund raiser for my birdy club. It has been educational and entertaining for me. I now know what slime mold looks like, how powdered cinnamon can be our friend, what root rot looks like (and how the poor plants look with root rot problems). I was lucky to find this forum to help me over some of the rough spots. And to help provide information on caring for the beauties! Here are some photos of a little expirement I am doing...comparing mostly catts in bark with catts in LECA. chck out the root growth for yourself.

    LECA seems to have an advantage over bark in promoting root growth. Here are my catts in a row.

    I think that would be cool....but I'd have to move into a really big house. lol I'd be getting visited by local cops around here due to the extra "lights" too. lmao Now that'd make things fun....around here the minute your electric usage changes drastically the local sheriff comes a'knocking to check out your house. So, for now I'll just keep mine on the porch.....I'll just have to get some bigger shelves.

    Cindiras, do you have holes in the pots along the side on the way up for air movement or just at 1.5" to 2" from the bottom? How big do you usually find the holes should be in order to prevent clogging?

    Richard, most of my S/H pots are quart size deli containers bought at a local grocery chain. The colored ones are 16 ounce plastic cups. The quart containers have two 1/4 inch holes drilled about 1/2 to 3/4 of an inch apart on level. No other holes for ventilation. The 16 ounce cups, I used a box cutter and cut a 1/4 inch by 1/2 inch slot in the side where the name of the manufacturer Is. I cut out the letter L. I also have some baby phals in clear plastic oldfashion cups, about 10 ounce size, with 2 -1/4 inch holes about 1/2 up from the bottom. Short cup, lower holes.

    Wow, big difference in those in the semi-hydro. Are you going to move the others now as well?

    Cheers,

    Yes! It has made a major differance. First I have to order more Ali flor/LECA. I see where I got this batch now has a larger package- 44 liter- available. When that comes, I'll have to make a run to the grocery store for more "pots".

    Hi! Are you using the LECA with the traditional s/h culture or are you just using the LECA as a regular potting medium? If as a regular potting medium, would they need to be watered daily since there wouldn't be a water reservoir?

    Hi Becca! Before moving to S/H, I had a lot of trouble with overwatering. Still have that tendancy, but the reservoir system has helped me curb the watering impulse. The small cups only have a small 1/2 inch deep reservoir, the 16 ounce cups have a 1 inch reservoir, and the quart containers have thier drain holes positioned about 1 1/2 to 2 inches up from the bottom. I check the little 10 ounce cups 2 or 3 times a week for signs of condensation on the sides. Usually water them once a week, sometimes twice. The 16 ounce containers get water once a week when they no longer show condensation on the sides, the quart containers go 10 days to 2 weeks between waterings. Usually. Some of the plants seem touse more water than others. I just check the cups every day or so to see if any need attention.
