6*F^2/(I*E)where F = F stop (aperture)
6 * 2.6*2.6 /(80*1/33) = 16.731 FC (wow, that is dim).

|Oil pressure gauge and Gardena fitting|
|Conveniently, one of the fittings that came with the oil pressure gauge happened to be just about the right size to self-tap into the plastic of the Gardena fitting. Yay!|
|Ooer, it actually works!|
|Here's a random shot of the calibration and storage solutions around the instrument which is sitting in pH 4.01 buffer. Note the pH had already drifted out by .01 in the time it took me to assemble the shot!|

|Two more buds on their way - yay! Judging from how quickly the last flowers developed, they should open in about 2 weeks or less.|

Grahamstown Tapwater: pH 8.20, EC 669μS/cm - quite alkaline and rather salty (for orchids).
Aquelle spring water: pH 7.2, EC 72 μS/cm - not too bad!
Distilled water: pH 7.05, EC 3μS/cm - pretty good, as you'd expect.
400μS/cm: Cattleya, PaphiopedilumThat means that even without fertiliser added, Grahamstown tapwater is unsuitable for all but the most commonly and widely grown orchids (Phalaenopsis and Cymbidium). And I suspect Disa are real pansies and need a lot lower than that! Buying distilled water and/or spring water to water your plants seems a little excessive, so I'm going to test some other possible sources, particularly spring water. Given that we live in a rented second story flat, there isn't really any feasible way of harvesting rainwater, and Reverse Osmosis units require plumbing modifications, unfortunately!
600μS/cm: Odontoglossum, Coelogyne, Lycaste, Oncidium, Masdevallia, Miltonia
800μS/cm: Phalaenopsis, Cymbidium

|South Africa's most beautiful indigenous flower next to some Disas.|
|Disas. Many, Many Disas! Note the irrigation pipe for flooding the growing bench.|
|Yeah, you guessed it - Disas!|
