Quantum Board Torture Test 2: This Time, It’s Personal

From Instagram live: Taking another run at overpowering a QB288, this time with an HLG-600H-54 and a boost converter. Sorry for the crappy quality and vertical video – the format it saves to isn’t great for watching on PC.

Hands-on Review: HLG Quantum Board Reflectors

Are the Quantum Board Reflectors worth your time and money? This video examines their effectiveness in an open air setting as well as in a tent.

Quantum Board Power Handling Test

This video covers the results of an experiment I did in order to determine how much power it’d take to destroy an HLG QB288 and QB304 Quantum Board. I was pretty damn surprised!

 

Hands-on Review: HLG Slate 3 Triple Heat Sink for Quantum Boards

Hey all,

I returned home this week after a stint of working out of town and came back to some really cool new gear waiting for me, courtesy of Robin at Horticulture Lighting Group. There’s so much that I want to get done, but the first piece I was eager to experiment with was their Slate 3 Triple heat sink. You can check out my video review below, or continue reading and I’ll hit all the important points in text form for those of you who brought your phone to the bathroom and don’t want anyone to overhear you watching grow light videos while you’re in there.

We’ll also cover wiring the boards in series and parallel, and look at how to properly match QBs with drivers so you can expand your kit or upgrade your driver. The next and final video in the review will review PPFD results from each of the kits and go over some final thoughts after using them.

In next week’s video, we’ll look into how the boards work, how to dim them properly, and how to expand your light with additional boards. Shoutout to HLG for sending me these kits to experiment with!

Samsung LM561C Strip Build: Finishing Touches

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:

Samsung LM561C Build: Testing PPFD

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.
