As is always the case, times have changed. When I started this blog almost four years ago, the focus was solely on the use of modern scientific methods for maintaining decorative indoor plants in containers (aka houseplants).
Since then, climate change and the green movement have taken center stage. There is constant chatter about local food production and community agriculture. Buzz words like locovore and slow food have entered our vocabulary.
Rather incredibly, the use of sub-irrigated (erroneously called “self-watering”) planters for personal or family food production has been largely ignored. All you need do is a site search on the National Gardening Association, American Community Gardening Association or all the USDA Extension Program sites combined and you’ll find very little how-to-do-it explanation of the benefits of measured sub-irrigation.
Is it simply ignorance of the subject or are there hidden agendas? I know from direct personal experience, for example, that most houseplant growers do not want their plants to live too long. Rather than grow the market, they much prefer to grow replacement plants for the ones you kill. Just don’t blame them for the fact that the plant died.
The widespread use of arcane drench and drain watering is a direct result of propaganda and scare tactics about soluble salts. Yes, soluble salts are a significant factor to deal with in well-lit greenhouse production where water and fertilizer are poured on the plants on a daily basis. The objective is to push the plants out the greenhouse door as quickly as possible.
That is not the case with the maintenance of container plants inside marginally lit buildings. Note the operative word maintenance, as in "staying alive" rather than fast growth. Greenhouse plant growing and the maintenance of containerized plants in and around buildings are two completely different subjects.
If you’re hooked on clay pots with drain holes and saucers, know that you’ve been mislead. I can’t say it any more plainly. No need to take my word for it, you can easily prove it to yourself. All you need is an open, questioning mind.
Open minds are what kids have and that’s the reason for donating my ten-year-old Inside Plants Science Lab for the good of public education in New York City where I now live. Teach the children. They will teach their parents. If you haven’t noticed, that’s a part of the new digital age. If you have a question about your computer, ask your kids.
So, have a first look at Inside Urban Green. Bookmark it and add it to your RSS feeds. I believe you’ll be glad you did.
Before my cross-country move from San Diego to Brooklyn, I bought a MacBook. Recently I set it up as a desktop computer with an auxiliary 24” LCD display. This revealed a significant problem with all of my plant photos.
They were shot on a desktop stage with a black cloth backdrop. I then used Photoshop Elements to remove creases, folds and debris from the desktop stage without altering the plants.
Unfortunately, I was unaware that my old CRT monitor was out of calibration. The photos that looked fine on the old screen were badly flawed. I will be re-editing all of them as soon as new software for my MacBook arrives. This has certainly been a lesson learned.
Update: All photos have been corrected.
The reason for my absence from this blog is that I took time out to move across country from San Diego to Brooklyn the city of my birth. It was an extremely difficult move in that it involved moving the entire Inside Plants Science Lab as well as my possessions. Doing this by myself in a 26’ U-Haul truck was a nerve-racking odyssey and I’m still recovering from it.
I now live in Bay Ridge, Brooklyn and the lab is temporarily stored in the science lab of the Ebbets Field Middle School.
If your interest is in modern 21st century methods of maintaining plants in buildings the archived contents of this blog are the equivalent of a book on the subject.
It is straight talk without all the mumbo jumbo mythology so common in the houseplant world.
Indoor Plant Hobbyists and Others
Although not organized as a book, topics are categorized. For example, click on Sub-irrigation or Inside Plant Care or Hydroculture/Hydroponics. There are other topics well worth reading if your interest is in modern methods of maintaining plants in buildings.
See additional Topics (left column).
There is also an extensive photo collection on Flickr.com. Have a look at Digital Age Indoor Plants.
Educators
If you are an educator read about the Inside Plants Science Lab donation program at InsideGreenNYC.org. There is also an outline of the program below.
If you have an interest in this project please contact me at bobhyland[AT}insideplantslive.org.
New Blog Coming
InsideUrbanGreen.org will replace InsidePlantsLive.org in the near future. The site is under construction. The scope of the new blog will include more emphasis on urban agriculture and methods of growing vegetables on rooftops and in small city spaces. The range of topics will cover food, foliage and flowering plants in and around buildings.
An outline of plans for the Inside Plants Science Lab project.
Using modern science based methods of maintaining plants in buildings will help in the early science education of young people. Urban horticulture, or agriculture, is a subject of ever increasing importance in the new urban green environment.
The growing of foliage, food and flowers should not be confined solely to in-ground gardening hobbyists who demonstrate a tendency to be techno-averse while resisting modern 21st century methods.
Learning about measurement and methodology instead of clay pot mythology will help on the path to higher science education for children of all ages. All students will benefit whether pursuing science careers or simply living in a densely populated urban environment having limited contact with nature.
Temporary Storage
The lab is currently stored in the Ebbets Field Middle School science lab, to be moved as soon as possible to an accessible location in Brooklyn. This will be used to demonstrate the program to interested schools and organizations in the New York City area.

Click to enlarge. This is an an UTZ pretzel container that was recycled to make this sub-irrigation planter. It was made using the same technique as the soda bottle planters .
The plant is a Schefflera arboricola that has been growing in one of my other sub-irrigation planters. It is now over 8 years old and in extremely good health.
There is one change that improves these planters. If you insert a strip of polyester backing material (1" wide in this planter) (AquaPad ) under the cap you will create a very functional wick. Just lay the wicking strip inside the cap and screw it on. This fastens it and creates a wick for capillary action from the reservoir into the potting soil.
Using this method the cap or lid in this case does not need to contact the bottom of the reservoir. The polyester wick bridges the gap between the cap and the reservoir bottom.
This planter is equivalent to an 8" grower pot. It cost nothing and is in my opinion better than the majority of so-called self-watering planters sold at retail.
You can see everything that’s going on…reservoir, soil moisture and the root system. You can either use it free standing with a high-tech look or install it in a decorative cachepot.

Vint Cerf is considered one of the "founding fathers of the Internet. He is also Vice President & Chief Internet Evangelist of Google. In this video, he justifiably evangelizes about the Growing Connection and the EarthBox sub-irrigation planter.
As said before, Google reveals all. I discovered a Google Custom Search of all the 50+ Cooperative Extension program websites across the country. These 10 mentions of the word 'earthbox are the sum total results of a search using this engine. The search provides little or no educational information.
Why is that we as a nation seem to have a department of agriculture extension program living under a rock. It is no wonder that horticulturists wonder about their future. (It's a pdf. Scroll down to page 8 ) MS Word file. Download file
Also read on the subject here .
I'll post the results of many more searches of these sites that relate to the maintenance of plants in and around buildings. They reveal how out of touch this program is with the realities of 21st century life and the issues of sustainability, water conservation and the environment.
In the meantime, run your own searches using this feature. A forewarning, you’re not likely to find much about modernity.

Speaking of capillary action and science education. It's bad enough that sub-irrigation planters using capillary action are called 'self-watering.' Now we have capillary action referred to as evaporation.
You might get some humidity in the air through evaporation, but it's not going to water the plant.
How does it work?
At the bottom of the planter, there is a 1-gallon reservoir. Through evaporation, the water in the reservoir moisten(s) the soil above it. The reservoir is refill(ed) through a filling tube.

This article is based on information from the National Science Foundation's (NSF) Research on Gender in Science and Engineering (GSE) program. It helps explain why I am donating the Greenscaper Inside Plants Science Lab. The plan is for it to go to ten different public and private educational institutions to help teach science to young girls and boys.
I'm by no means a science head, but more of a do-it-yourselfer. Even I understand capillary action. The houseplant community, which is dominated by women, seems to have little or no understanding of this basic principal of physics.
Use of the term self-watering, clay pots with saucers along with finger poking to measure soil moisture are significant indicators of a lack of science education in the houseplant and container gardening community.
Evidently, the problem starts along about the 8th grade when girls drop out of science. Sadly, the older women in the houseplant community are testimony to this educational failure. Unfortunately they are the authors of most of the books about houseplants.
Myth 1: From the time they start school, most girls are less interested in science than boys are.Reality: In elementary school about as many girls as boys have positive attitudes toward science. A recent study of fourth graders showed that 66 percent of girls and 68 percent of boys reported liking science. But something else starts happening in elementary school. By second grade, when students (both boys and girls) are asked to draw a scientist, most portray a white male in a lab coat. Any woman scientist they draw looks severe and not very happy.
The persistence of the stereotypes start to turn girls off, and by eighth grade, boys are twice as interested in STEM (science, technology, engineering, math) careers as girls are. The female attrition continues throughout high school, college and even the work force. Women with STEM higher education degrees are twice as likely to leave a scientific or engineering job as men with comparable STEM degrees.

Update 2: The porn photo defacements have been removed. My photos look normal again even to me as the account owner.
Update: I had a friend check my Flickr account and evidently what I see is not viewable to the public at large. I'm grateful for that but it does not change the opinions expressed here.
There has been a series of malicious defacements of both this blog and my Flickr photos. It’s best not to access my Flickr account currently.
Because of some past personal experiences, I am highly suspicious that these attacks are from someone in the horticultural community rather than some stray nutcase.
I have no personal enemies that I know of but I do know that I am considered "the enemy" by some for publishing this blog. I've been called the enemy right to my face.
If you think that houseplants are a non-controversial, innocuous subject, think again. I've personally experienced an anti-technology, anti-science, reactionary element in the horticulture community whose positions on the subject could easily be described as zealotry.
Short of zealotry, overly sanctimonious opinions, particularly on gardening blogs are an every-day occurrence in my research. Placed in the perspective of our current polarized national politics and world events, I wonder where we are headed as a nation.
I have a lot more to say but I’m in the middle of watering plants in the lab. This job will end before too long as I am in the process of donating what I now call the Greenscaper Inside Plants Science Lab.
Note the word science, for that is the operative word. I will donate this extensive database of information along with the plants to help teach science to kids, particularly young girls.
If you know of anyone connected to a NY Metro area educational institution or non-profit that is working to further the science and environmental education of young people, please contact me. The Big Apple is where the lab and I are headed by the end of this month. No Sleep Til Brooklyn
My vision is to see this work expanded 10 fold and then 100 fold…or more.
What’s your opinion?
NOTE
Sorry that comments don’t work. There's a software bug that I don't know how to fix. Please email your comments, questions and suggestions until I can get comments working again. Thanks!

And there it was on display outside the entrance to Trader Joe’s for just $2.99. Into my basket it went and now the Sweet Basil is living happily in a 3-liter recycled bottle. The bottle planter will be around long after the 1-gallon plastic grower pot is dropped in the recycling trash.
It took a bit of root pruning to get it into the bottle planter but that’s no big deal. I learned long ago that a sub-irrigation planter acts like an IV, delivering the precise amount of water based on the plants past water usage. Many times I've cut 1/3 to 1/2 the root ball of a plant before installing it in a sub-irrigation planter without the plant even blinking.
There’s no way that primitive top watering methods will produce such evenly distributed moisture throughout the root system—always remembering to never add so much water that it rises to the surface.

Click to enlarge. The photo shows the size comparison between 2 and 3-liter recycled bottle sub-irrigation planters.
The 3-liter bottles contained Shasta Twist Lime-Lemon Soda. These planters will hold any 6” size potted plant. You could also use them to start vegetable plants such as tomatoes and peppers.
I would buy this soda just for the bottle planters; they are that good. This is not plastic that will end up in the dump or the recycle bin. These are sustainable planters for maintaining sustainable indoor plants.
