Follow @pholowko Want to be able to grow your own garden and be able to eat what you grow? Want to garden without using only what is already in the soil, and still produce amazing results? Gardening Rhythms is a show that depicts a natural method of gardening lifestyle using observation, innovation, common sense and understanding the practical use of micro biology. This show teaches you how to garden without using chemicals and fertilizers, and it’s designed to give you tips to become a savvy home gardener. Paul Holowko’s father, who holds a Masters in Agriculture, taught him how to prune trees using loppers and a chain saw at the age of 10. At 13, he expanded into beekeeping. As Paul got older, he supported himself through college doing landscaping. Paul is an accomplished Electrical and Computer Engineer, with three master’s degrees and many patents. He brings aggressive innovation, attuned attention to detail, and creativity to gardening. Currently, Paul is experimenting with developing soil by planting different kinds of plants in it, building vertical gardens, developing methods for increasing food production; changing soil chemistry so you can grow any plant, and natural methods of pest control.

Thanks for another great video on CELSS. Its sounds like your getting in plenty of data. Have you created any spreadsheets or models for tracking or simulating a CELSS system? I was thinking that might be helpful in estimating size, quantities and other items to go into a biosphere.
I saw your previous video mentioning LEDs providing “straight light” as compared to “bouncing light” from a typical incandescent bulbs. I thought that all light is basically “straight”. Couldn’t you use a light diffuser in the biosphere/CELSS, like those crackled glass diffusers over florescent light tube fixtures?
Spreadsheets are so 2000s.
I’ve build programs and equations to predict populations of bacteria, protists and fungi in the future depending on the amount of food available. The embedded processers, like you saw in the video, solve the differential equation using Taylor Series and other numerical methods for solving differential equations. This is nothing new. People have been trying to write equations like this since the late 1800s. In real time the embedded CPUs (or PICF184550 chip) solve prediction equations. Checking the calculations to the actual numbers can be challenging. A lot of times it has to be estimated on the measurement side. Since the CPUs run on a 48MHz crystal, it takes a couple of days to produce a solution. Sometimes you wander if your program is stuck!
I can post the equations and the numerical methods for solving the problems. Numbers the equations solve are only good for a week into the future. The models are similar to weather predicting models. The differential equations are used to predict what kind of species of micro-organisms will grow together and produce a climate. It’s not how big your Biosphere is, but how you use it.
On your second question…. you are almost right. Light does not bend except in high gravity situations. However, light reflects off the walls. I was indicating bouncing light from HID lamps can provide more light because it exits the bulb at different angles. (BTY, incandescent lights are not practical for greenhouses, homes or for anything other than an Easy Bake Oven. It produces too much heat for the amount of light produced. (Besides, the incandescent lamp is invented by someone very vulgar and obscene; you can tell I’m a fan of Nickola Tesla). Light rays hit walls and other reflective surfaces illuminating the understory of plants. LEDs shine everything on the leaves and doesn’t bounce light very well; hence, a minimal amount of stray light. I tried a diffuser with limited success. This is the main reason hydroponic stores are not willing to carry LEDs. It’s not very good for growing pot; however, that is the place to buy them. You can order them online as well.
I had the best luck with hanging the LEDs lights down the sides of the tank and shining the plants sideways rather than from the top.
