At around noon today, the summer solstice, under a clear sky, I measured the PAR. It was around 2000 (expected around 1900). Under Willy's LED light, the PAR is super high at the LED's but 200 at 21 cm. below the lights, the same as for new T5HO Sunblaster bulbs. That's why Sarr's need the Sun (and tomatoes too).
Nice, Lloyd! I got half a dozen sarrs from labine but have yet to make a bog pot. I may yet make an inground bog. I thought it might be too cold for that but I had all sorts of veggies re-animate this spring after a winter under the snow. Maybe I'll add a bale of hay for insurance.
More than 1 week of full sun, >30°C, no rain. I just put my microbogs in the shady part of the deck for now.
Even with the earthboxes full of water the tomatoes are wilting a bit at the tips. I'm rotating the plants 180° during full sun to let the leaves cool a bit.
