Reddit reviews Plants from Test Tubes: An Introduction to Micropropogation

Well, Plants from Test Tubes will have you doing it like an amateur. The "pro" part is the next 20 years.

edit- I've made some modifications to this post for educational purposes since I usually don't talk about far red light

Yes but that is 735nm LEDs being sold and you don't use 735nm for the Emerson effect to increase photosynthesis. That's simply not how the photosystem works in higher land plants.

Some types of algae or photosynthetic bacteria can have more than just chlorophyll types A and B found in higher land plants which can be far red sensitive. Chlorophyll F was recently discovered, for example, that will work with far red light. Chlorophyll D is also far red sensitive. Chlorophyll A and chlorophyll B are not far red sensitive in a solvent or have very limited sensitivity in a lattice. This can cause a lot of confusion.

Increased photosynthesis rate is a product claim and the burden of proof is always upon the person making the claim.

As for rooting, my claim that far red can be different for different plants comes from studies found in this book (I have the 1996 1st edition):

I also work with far red light. You need a specific far red light meter or a spectrometer to even make a simple measurement as even the $800 LiCor quantum light meters won't work with far red light. I don't recall him having either but I could be wrong here (I require a spectrometer for my work). This is important since some of the far red sensitive phytochrome proteins can work at different far red light intensities.


edit- clarification and you can see in this spectrometer shot that far red light is mostly just reflected off a leaf:

And 1 puck per 9 square feet? No, I'm calling that out after looking at the LED data sheet. I had some minor inside information under NDA from a subcontractor on the $4.88 million LED study by Purdue and MSU and they were using much higher far red lighting levels to elicit a response.

One can get a UFO light with a far red LED or two in a 5 gallon bucket and that will put close to the same far red light per square foot as that puck if only one puck is needed per 9 square feet.

Example of what I use which puts out more far red light than that puck:

Plants from test tubes is a great book

This may be something worth looking into.
