Parallel Strip Build Tool

Since a lot of people have been looking for help on their strip builds, I figured it’d probably be helpful to have a calculator just for this. Now that we’re seeing more and more of these systems being built, it has become apparent that running all strips in parallel is the way to go – it’s expandable, the math is easier for large numbers of strips, and wiring is less confusing, so I’m only doing this for parallel builds. Check out the parallel strip build tool below!

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.

HLG 550 Assembly and Testing

In this video, we assemble a Horticulture Lighting Group HLG 550 from individual components and then test it out.

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!

 

DIY LM561C Build – Grow Update

Hey all,

It’s a long weekend for me (Canada day – huzzah!), so I’m really phoning this week’s post in so I can get oot and aboot. The wife and I are making super-deluxe poutine tomorrow with ALL the fixin’s (sour cream, onions, bacon, smoked meat, cheese curds [of course], and 2 types of gravy), and I’m SO excited to laze around, eat poutine, and drink beer tomorrow. I racked my brain for something simple to write about tonight and decided I’d snap a few quick pictures of my plants that I’m growing under my DIY LM561C strip build and share.

HLG Quantum Board Kit Review: Part 3 – PPFD Measurements

The final video for the Quantum Board Kit review. Thanks again to HLG for sending the kits – these things rock!

HLG Quantum Board Kit Review: Part 2 – Operation & Analysis

In this second video, we’ll go over how to dim each of the QB kits, then take a closer look at the LM561C, and how the Quantum Boards are physically laid out. 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.

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.
