Horticulture Lighting Group (HLG) has certainly made a name for themselves with their hugely successful Quantum Board lights. When HLG first released their original boards in 2016, COBs were king – it was all about CXBs, Veros, and CLU048s. Quantum Boards totally changed the game though. HLG pioneered the use of modern, high-quality mid-power diodes in the DIY LED space and, in our opinion, are largely responsible for the shift away from COBs to this new tech. Now, a year and a half later, they’ve built upon the success of their first design and have put forward a light that is objectively better in every way: the QB288 V2.

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:
Hi everyone.
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.
