Each Microgreen 3-Tier LED Walden Grow Tent Kit comes with six Active Grow 38W 4FT LED Propagation Luminaires in Sun White Spectrum and twelve 1/8" Hydroponic Hangers. These high-performance LED grow lights connect via daisy chain cables and can be hung using the provided 1/8" Hydroponic Hangers (recommended hanging height: 6-12" above plants). Each 3-Tier Walden Grow Tent comes with three 47.5"x24" shelves (assembly required), five 6" ducting ports, two 4" electrical ports, three roll-up mesh air vents, two fan/filter straps, a removable spill tray and installation guide.
What Can I Grow?
With the Microgreen 3-Tier LED Walden Grow Tent Kit you can grow microgreens (wheatgrass, broccoli, amaranth, watercress, sunflower, etc.), leafy greens (green butter, romaine, green crisp, etc.), herbs (arugula, basil, chives, rosemary, thyme, etc.), and more in 10×20 trays, small-medium sized pots and small hydroponic setups.
Sun White Spectrum
The spectrum that started it all and can grow almost anything is a full-spectrum light formulated to mimic natural sunlight conditions and is ideal for every stage of plant growth. High CRI 95 light accentuates plant coloration and makes visual inspection easier. Includes 660 nm (red) and 730 nm (far-red) wavelengths to boost photosynthesis rates via the Emerson Effect.
Adjustable 3-Tier Shelving System
3 sturdy shelves (47.5"x24") provide up to 32 ft of grow space and support up to 45 lbs. each. Easily adjust shelf heights to meet target lighting requirements for different plants. Shelves can also be removed if a taller grow space is needed. EcoWhite PEVA – Triple Layered
All Walden Grow Tents are manufactured using industrial-strength zippers and 100% EcoWhite PEVA material. The toxin-free material creates a safe, stylish and easy to clean growing area that keeps insects and other pests out. The triple-layer design is composed of a 600D canvas exterior, a vinyl light-blocking center and a white vinyl interior that is 10% more reflective than even the most reflective mylar tents.
Double-wide Front Doors
Extra-large front viewing windows (18.5"x50") let growers check on plants without disturbing humidity or temperature. Window covers roll back and secure with velcro straps.
2-year Warranty All tents come with an industry-leading 2-year manufacturer’s warranty.

A wonderful primer for those discovering the amazing world of generative AI
Format: Paperback, Format: Paperback
Somewhere in the past year, ChatGPT has gone from "cool, interesting, amusing" to a massively valuable work assistant capable of writing Python scripts, analysing data, and doing lots, lots, more. The key to this? The rapid evolution of OpenAI's GPT models and making my first forays into prompt engineering.
If I thought I was getting good, though, this book took me reminded me that I'm just scratching the surface. Halfway through the first chapter I was already furiously scribbling notes in the margins for what I could do better with my prompt writing and by the end of the text I felt like I had gotten a very good grounding - not just in GPTs specifically but in the bigger picture of how these hugely powerful tools were trained and came to maturity.
I imagine that few will argue with my assertion that there is lots of hyperbole and "noise" in the AI space right now which, as ever, makes it hard to pick out the signal from the noise. Which is precisely why I sought out an O'Reilly title and I'm very glad that I did.
Thorough, excellent, and I hope that this edition will be the first of many. As this rapidly maturing field scales and matures I think that prompt engineering will be an essential discipline to master. Pick up this text to get a good foothold on things.

Understanding AI prompts as a science
Format: Audiobook
Prompt engineering is the art and science of finding the right words to generate the right responses from artificial intelligence (AI). It's becoming a skill in-demand in today's workplaces. It's also becoming an essential skill for life. To understand prompt engineering, you must understand how AI tools understand their inputs. This book explains that to you in many forms.
It covers prompting as it intersects all the major AI disciplines, like general prompts (as in a ChatBot), fine-tuning, and retrieval-augmented generation (RAG). It also introduces how prompting intersects a couple of image-generation tools.
As a scientist, I appreciate the theoretical approach to these practical matters. Too many people are hacks at AI these days, and any technical understanding can rapidly advance an individual's effectiveness. Prompt engineering is often made fun of as a "soft" topic, but as this book demonstrates, it intersects all the major AI areas. Presumably less garbage in means less garbage out. This book shows how you can make that take place.
As typical for O'Reilly materials, this book appeals to people who desire an intermediate-to-advanced understanding of how AI works. It's not for the casual user. Anyone technical involved in professional knowledge generation using AI can benefit from understanding the dynamics "under the hood." It's a good, though perhaps not ground-breaking, textbook for those of us unable to take a class in the subject. Prompt engineering may be a soft topic to many, but books like this ground the field in the science that can make or break a digital or software product.
