It’s been beautiful outside this past week so it’s been tough to get motivated to finish my DIY Quantum Board build, but I got it done today. I’m eager to see how the plants under these lights do – I think they’re going to work out really well! I’ll be growing lettuce, basil, swiss chard, and kale in Kratky totes. The nice thing about Kratky is that all you need to do is plop your seedlings into little mesh pots (net cups), cut these pots into a tote lid, then fill the tote with water, add nutrients, and just monitor the pH. The roots will grow down into the nutrient solution and drink away at it as required, so no watering is necessary.
Below are the steps I took to finish this light, but first, a quick recap of my final parts list:
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.
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.
