Hi. I have over 40 orchids in semi hydroponics for about a year. I had them it plastic net pots with a tray underneath as a water reservoir. In the past year they have grown lots of healthy roots. So many that they went crazy and grew out of all the holes in the net pots. Then they become very hard to manage proper moisture. They start to look a little bit dry at times. So, to manage the roots better and increase humidity I moved them into a more closed plastic pot. Still has more holes than most Orchid pots, but obviously not like the airflow you get with a net pot. They have been in these for a couple of weeks and now many,many,many of roots seem to be rotting. Almost all are rotting totally or starting to rot at the tips. I unpotted one to check the inside and almost all the old roots have rotted. Should I move them back to net pots? Or just hope they will grow new roots and adapt to the new , constantly wet conditions with less airflow?? Please help!! Also, there is algae growing inside the pots. That didn't happen with the net pots. Is that going to cause problems?? Both the net pots and these pots both seem to have problems. The roots with the net pots grow very healthy but it is hard to control the humidity and hard to deal with the crazy growth through the net pots and these new pots seem to be too moist and are rotting all the roots? What are everyone's thoughts? Wait it out and let them readjust? And if that is the case, what to do about all the old rooting roots? UNpot them in a month or so and clean them out? and plant them back again? Thanks for your help.
