I have 4 6400K 32W T8 fluorescent bulbs (spaced out over about a foot), about 1'-1.5' above the plants in the light box (which I think is 5'x2'x2'). The Pseudolithos are near the center of the box, close to the brightest spot.Euphorbus wrote:I'd be interested to hear what strength of lighting you use, and how close you keep it to the plants. I've also been wondering how best to administer water, given how fussy these plants seem about having water on their bodies. I usually water from the bottom, but perhaps a largely pumice mix wouldn't soak up water adequately for any to reach the roots using this method?
I water the plants from above (the mix is quite porous, and even if I could successfully water from the bottom I'm not sure I'd want to soak the medium). I water between the edge of the pot and the plant body so there's not too much splashing. I doubt it'd make any difference, any drops or wet patches generally dry off within a few hours given the low RH.
