5.0 von 5 Sternen Best book I've come across so far for LED lights, and hydro/aqua/aeroponic growing 27. November 2015
Von Kaptkaos - Veröffentlicht auf Amazon.com
Format: Kindle Edition Verifizierter Kauf
I bought this book specifically to better understand LED grow lights and its well worth every penny. I've read a couple of truly mediocre books on hydroponics so far and for the low price of this book, I was skeptical at first. I'm happy to say that I found this book truly useful. I know know what to look for when purchasing and LED grow light. The author goes over the specific color frequencies, and ratios of those color frequencies needed to make a good grow light. The author is up-front in saying that more data is needed before anyone can claim to make the perfect grow light, but the biology of most plants require some fairly basic combinations of colors/frequencies.
Aside from the insight gained on LED lights specifically, I also learned a lot about planning my grow room, including how to ensure that my equipment does not strain my existing circuitry, light control, etc. As a novice to hydro/aeroponics, I found this book to have tremendous value. I'll keep it on my digital bookshelf for many months to come. As it turns out, the first grow light I purchased on Amazon was well within the suggested lighting values recommended by this book. Dumb luck on my part, but good to know in hindsight that I made a lucky guess. Since then I have purchased that same grow light, plus a different one that incorporated UV and IR spectrums. If you are looking for usable advice for growing plants with LED lights, this is the book to get.

5.0 von 5 Sternen Some Great Growing Information, BUT.... 31. Mai 2015
Von DKF1219 - Veröffentlicht auf Amazon.com
Format: Kindle Edition Verifizierter Kauf
This book has a lot of information about general indoor gardening that is very good. It has too much quite technical stuff--chemistry and physics-- that most people will not be able to understand. I laughed when he advised all growers to take a college level chemistry class. A college level chemistry class is going to require some higher math knowledge and some kind of science behind you helps. Some people are simply liberal arts people, it doesn't mean they cannot be wonderful gardeners.

Unfortunately, it really didn't have enough specific information about the differences between growing with LEDs and HIDs. I was excited to find this book as I am one switching from HIDs to LED, but was disappointed upon reading it. Most of it is general and logical...less heat, less ventilation needed, may need to adjust your nutrients, without any specific information. For instance, in other reading I have picked up some tidbits. I have read that you should trim up the bottoms of your plants, and spread them out to allow for more light penetration. I have read that you feed lighter because the LEDs help the plants utilize their nutrients better. I have read that the lights need to be generally 18-24" away to get full spectrum spread and prevent bleaching. I was looking for specifics, but this book offered only broad generalities in the difference between HIDs and LEDs.

I gave it a 5 star rating though because it does offer very good general indoor growing information that would be helpful with any type of lighting. The section of primary, secondary, and micro nutes was very informative, especially for a new indoor grower. While I do not agree with the author on everywhere (that just doesn't happen in real life), the book overall is full of useful information and would be an asset to anyone who does indoor gardening.

Lastly...the book is very well edited and I found few error or typos, which drive me crazy. One of them sticks in my mind. Tell me....being an MVA, the author certainly has to know that the word "nat" has a "g" at the beginning?

4.0 von 5 Sternen Good information on a relatively new lighting system. 30. September 2016
Von Charlie Weir - Veröffentlicht auf Amazon.com
Format: Kindle Edition Verifizierter Kauf
Although he avoids mentioning it nearly entirely, this is about growing cannabis under LED lights. Not to worry, it still counts for food crops. Just ignore all the references to weird grow media and nutrient solutions and his advice will help with your tomatoes and such.

.I don't know when Mr Sloper wrote this - as opposed to when it was published - but good quality LEDs with 8-9 frequencies at 600w (but drawing about 300w) - use 3w not 5w bulb systems - are now available in the $150-200 range online. This really makes LEDs practical for small gardens.

Well worth reading, especially since there are so many misconceptions about this option.
5.0 von 5 Sternen I'd love to meet this guy 3. Januar 2017
Von The Hamburgler - Veröffentlicht auf Amazon.com

I found the book informative but didn't really get any specific answers. Which is a good thing because the fact is they aren't out there. This guy doesn't present his theorys as scientific fact like most people do. I feel I now am in a great place to start experimenting with LEDs having read it. I loved the last chapter and found it very humorous. This guy is smart and has a great attitude. I would love to pick his brain and hear about specific research or experiments he's done. I would recommend this book to anyone who wants to start growing with LED lights and anyone that is closemind

Anyone already using or considering using LED grow lights should get this book. First substantial information I've come across about the fundamentals of using this type of lighting for indoor gardening. Very informative about all aspects! Well written!
