Hi Ocelaris,
Growing orchids as well as you obviously are shows quite a bit of skill. You may think none of your's are difficult but how many people could manage what you have?
I'm at 900ft elevation, with no farms upstream, and the well is 500ft deep, so there is very little surface water contamination. The soil is glacial sand with almost no clay and only a 6inch biomat so I suppose any soluble rock must have eroded millenia ago.
Regarding RH, I have 1gal/day ultrasonic humidifier that runs only during exhaust-off (<85F) and the plants are sitting on trays filled with gravel and runoff. Since I use only fluorescents and the case is in my basement (~60F), the exhaust comes on for about 1 minute every 5 min. At the end of the exhaust it takes about 30 sec. for the RH to get back to 70%. I have 2 RH meters, the human hair meteer gives me instantaneous readings, the cheapo that came with the humidifier is slow and reads a constant 65%.
How big are the particles of Isolite? I couldn't find any pics on the web. |
