I got two spider farmers and a light meter shows that each puts out about 800 foot candles 30” up from the bench. So I either need to double up or augment with another bulb. For now I’m trying some metal halides leftover from my aquarium days.
I have grown under LEDs for 13 years, using a handful of different types over the years. Most of my Cattleyas are currently under Spider Farmer SF600 74 watt bulbs. About $110. They are 40 inch long rectangular panels that have full spectrum and produce enough intensity for high light plants at 7-10 inches above the top of the plants. They would cover a width a little less than 2 feet. Lower light plants wound have the lights higher up.
