In a previous post, I built a pair of space buckets to start my 3000K and 5000K peppers in. The buckets worked excellently – they made it really easy to control temperature, humidity and airflow, and they got my peppers off to a great start. One of the best features of the buckets was how much light made it from the COB down to the plant canopy – especially after the walls were painted white. Off of a single Vero 18 COB, at the very bottom of the bucket I was getting a PPFD of 500 µMol/m2/S and at 12″ away from the COB, I was getting 1,100 µMol/m2/S. Having seen how well these worked, earlier this week, I set out to test out another popular “Space” device: the mighty Space Tote. Continue reading
As I’m getting my shit together for this build, I’ve been testing a few different things along the way. This weekend, I assembled my strips into 2 lights that would be similar to the Horticulture Lighting Group’s QB288 boards. Each of the lights is comprised of 12 strips with each strip containing 24 diodes, for a total of 288 diodes per light. For now, I just taped all the strips together, then fastened each “light” to a piece of wood to be able to hang them easier.
Hey all! I hope everybody had a good weekend. Mine was filled with nice weather, good friends, and a few IPAs.
On Saturday, I got things rolling on this Samsung LM561C mid-power LED build and I’m liking what I’ve seen so far. I’ve tested half of the strips and am happy to say that I’ve got no failures yet, and they seem to be very uniform in terms of brightness and voltage drop.
One of the go-to lighting metrics of greenhouses is DLI, or Daily Light Integral, and you may see this acronym when you’re trying to figure out how much light a specific type of plant needs. Put simply, DLI is a measurement of how much usable light hits a certain area (one square meter, to be exact) per day.
The latest tech to get the LED growing community all riled up has been dubbed “Quantum Boards” by the fine folk who designed them over at the Horticulture Lighting Group. These things have created quite a buzz across the usual forums that growers frequent, and for good reason. If you haven’t heard of them yet, you’re likely wondering what exactly a Quantum Board is and what’s so great about them.
