ThinkGrow’s Model H & Model H-Plus LED Grow Light is specifically designed for high PPFD cultivation practices in vertical farming. These full-spectrum LED grow lights feature an adjustable spectrum design for enhanced production at every stage of plant growth.

Both models are designed with a single Driver bar cross-connecting 8 LED light bars and includes a 12-foot 240V power cord and 16-foot extension cable.

High Performance

Both ThinkGrow Models are equipped with 8 LED light bars which can be suspended only 6 inches above the canopy, and feature Samsung full-spectrum LEDs which most closely replicate natural sunlight.

  • Model H generates a PPF of 1700 and an efficacy rating of 2.7 μmole/J using 630 watts of power.
  • Model H-Plus is a true 5-foot-wide fixture with 720 watts to power both full-spectrum and Samsung 660nm Deep-red LEDs, creating an 18% increase in PPF of greater than 2016 μmole/s, with 2.8 μmol/J efficacy.

Adjustable Spectrum

The ThinkGrow Model H & Model H-Plus drivers have on-board dimming with digital display for accurate control of light intensity during different growth stages.

Group up to 10 multi-bar LED lights together and control simultaneously or individually with the TrolMaster Hydro-X Pro controller, or use the LMA-T lighting adapter to control full spectrum and deep red output levels. These adapters are daisy-chainable for up to 256 fixtures.

With the ability to fine-tune the spectrum, growers can experiment with different spectrum “recipes” to get the most produce from their efforts.

Find Out Who Was the Legal Secretary
Format: Hardcover
I ordered this book after watching Nuremberg with Michael Shannon and Russell Crowe because I wanted to find out who was the woman accompanying Justice Jackson to Germany. Yes, that was not his wife, it was his legal secretary, Elsie Douglas. This book is the only source I could find that goes into any detail about their relationship. What it provides is nowhere near salacious, because it is evident that Jackson took his secrets to the grave. What details it does provide about the evident love triangle that existed in Jackson's life for many years is quite sufficient to explain the events of Nuremberg.

Well written. Factual sloppiness.
Format: Hardcover
Good insight into Jackson’s approach to the law. Thoroughly researched. Well written. However, Professor White made two egregious factual errors, both of which are an indication of sloppiness on his part, as well as that of his editors and peer reviewers. First, he refers to the World War 2 Chief of Naval Operations as the Secretary of the Navy. Second he states that Los Alamos National Laboratory is in California.

Judging Jackson
Format: Hardcover
Readers interested in FDR's era, the post-war Nuremberg Trial, and/or such important U.S. Supreme Court events as the Rosenberg spy case and Brown v. Board of Education will enjoy this well-researched book. Illuminating insights as to the characters of his fellow members of the High Court, especially Justices Black and Douglas, are also present. Of special interest in today's world is Justice Jackson's thinking on the limits of Executive Power in terms of war powers and foreign relations. I do think non-lawyers will be less interested when the author, a legal scholar, sometime goes into depth exploring aspects of Justice Jackson's thoughts on opaque technical areas, such as diversity jurisdiction under the constitution. And, I fail to see the need to spend much time on Justice Black's two children, as is done in chapter two "Family Matters." Why do I need to know that his daughter was a mediocre student in college or details about her early love life? Professor White clearly admires Robert H. Jackson as a fine advocate, brilliant writer, and independent judge, while noting some of his flaws. All in all, a good biography of an important American.
