Greenhouse Winter Wonderland

When last we checked in with Mr. Greenhouse we were finishing up the structure, covering it with shade cloth, and outfitting the interior. That seems impossibly long ago, but it was only this past summer. Summer is long gone, and cold weather is here. There are two times when a greenhouse really comes in handy: keeping things cool in the summer under the shade, and keeping things warm in the winter.

Preparing for winter by removing the shade cloth and putting on plastic seemed easy enough—sure, we’ll just pull off the shadecloth, roll it up, and pull the plastic over. No problem! Ahem. It was a lot of work. Especially because the weather was preparing to change, and it had been windy for several days. We waited weeks for a calm day, and eventually decided to try it on a nice morning with just a hint of breeze. It was a beautiful day.

Getting the shadecloth off, truth be told, was a cinch. Just un-clip the sides and pull it off. The next job was to pull the plastic over. We bought a large roll of plastic, 55′ long and 44′ wide. It’s wide enough that the sides hang down to the ground to cover our tall windows. I tied a one end of rope to one corner of the plastic and the other end to a roll of duct tape, which I then tossed over the hoop frame.

We pulled and pulled, and inch by inch the plastic came up over the hoops. Amazingly we had no tears. We got it centered, and started securing the clamps along the side. That’s when the wind came up.

In spite of the wind (which was not much more than a breeze, but that much plastic acts like a sail on a sailboat), we managed to get the sides clipped down and secured. All was straight, tight, and beautiful with no tears or holes.

To attach the sides we used the Tube Lock base and clip that we procured from Greenhouse Megastore. On the ends walls we used the Spring Lock base and clip. After using both I can say I highly prefer the spring locks, and I won’t be using the tube locks again. The tube locks are very strong and look nice but they have a tendency to slice through the plastic if you put too much force on it. The spring locks will not harm the plastic and are extremely easy to install – just thread the spring lock into the channel of the base, and it holds everything very securely.

The sides are rolled up using a long pipe clipped on with fabric clips from FarmTek. We added a hand crank to the end of the pipe; while not absolutely necessary it makes opening and closing the sides quick and easy. On a sunny day the temperature inside can climb into the high 90s, even if the weather outside is cold, so it’s important to be able to open the sides to vent the heat.

Cold Weather Is Here

Now that cold weather is here we have the sides down most days. It’s cold outside (at least it seems cold to us Texans), but it’s nice and toasty inside. Without heat, on a cloudy day the temperature inside is usually 5-10° above the outside temp. On a sunny day it could easily be 20-40° warmer.

I’ve built out the inside with tables for seed starts and microgreens. We now have two separate aquaponic systems. In the photo below, you can see the four grow beds—two on the right and two on the left. The grow beds on the left are recently completed, and we’re cycling the system right now – it’s almost fully cycled! The ones on the right have been fully cycled for months, and are verging on becoming a jungle. We regularly have to go in and hack back the nasturtium. The tall plants that you can see growing up the frame are cherry tomatoes. Yes, it is December.

Greenhouse Wide Shot

We do have many days and nights below freezing here, so we had a propane tank installed and hooked up Mr. Heater. It’s just a basic 30,000 btu blue flame heater, but its best feature is that it’s ventless, which means low installation cost. Last week when the temperature was below freezing for the entire week and all our outside water froze, the greenhouse was nice and warm and never got below 45° inside. While I like Mr. Heater, next year I’m hoping to look into warming the greenhouse using compost instead of propane.

Mr. Heater

We’ve set up a washing, cutting, & packing area in the back of the greenhouse. This is a wonderful addition because we can wash our hands right there in the greenhouse before working. It’s a wonderfully convenient place to harvest microgreens, and it’s easy to sanitize so that we can maintain high quality and good safety. Everything that we need to harvest and pack is right there where we need it.

Here are some of the things we have growing inside right now:

Mixed microgreens: Daikon Radish, Garnet Mustard, Chinese Cabbage, Purslane, Beets, and Swiss Chard.

Raft Bed Construction

Our next project is raft beds for the aquaponic system, also known as deep water culture (DWC). Water will drain out of the gravel media grow beds, where it is filtered by the media, plant roots, and the nitrification process. Nitrification is the heart and soul of our system and what makes aquaponics work. That’s a topic for another blog post.

The raft beds are basically constructed like a deck, and then I’ll add strong sides and line it with Dura Skrim. We’ll then float “rafts” that will support the plants on the surface of the water. The plant roots hang down into the water and draw nutrients up from the water. We expect to be able to harvest many dozen heads of lettuce each week from this system.

Raft bed framing

The media beds are plumbed so that they can drain either directly into the fish tank, or out into the raft bed.

Here is a picture of our fish tank, showing the drain from the grow beds.

All a lot of work! And ongoing. We’re never short of things to do. But the end is nigh. After the raft bed is complete we plan to get good at growing greens, work on our consistency and quality, and reap the rewards of our labor for a while.

Then, on to the next greenhouse!

Thanks for reading. I will leave you with this, our aquaponic grow bed from an earthworm’s point of view:

Unlocking Nutrients in the Soil Food Web

Lately we have gotten the learning bug, and we’ve been teaching ourselves all about the soil food web, and the bacteria, fungi, arthropods, and other creatures that inhabit and enrich our soil.

Our latest experiment with different soils yielded some really interesting results.

About two months ago we planted tomato seedlings in two different types of soil, just to see what would happen. We planted two trays of tomato seedlings. Each tray was planted half with Miracle Grow potting mix and half with our own in-house mix consisting of coconut coir and worm castings. Being in the same tray, they were all watered and treated the same.

The photo below shows a stark difference between tomato seedlings planted in Miracle Grow potting mix (front) and our coco coir mix (back). All the seedlings in this tray are two months old—they were all planted at the same time. The six seedlings planted in Miracle Grow are only about 2-3 inches tall, if we’re generous. They didn’t amount to much. The five behind, planted in our seed mix are about 8 inches tall on average.

Six of the healthy seedlings were subsequently moved to pots, with more of our rich coco coir and worm castings mix. They have been watered with compost tea and dechlorinated water. They look really good, in my opinion. This is what you might reasonably expect to see after being transplanted to a larger pot.

Now look at the photo below. This is a plant from that same batch that was subsequently planted in our aquaponic grow bed. I can’t stress enough that this is from the same batch of seedlings, planted on the same day, two months ago. See the empty cells in the tray above? This plant is from those cells. There are several plants in this bed – all of them are over 18 inches tall.

For comparison, here is a fancy chart showing the relative growth of each of these different tomato plants. As you can see, the tomato in the aquaponic grow bed is out of control.

One of the key features of aquaponics is that it produces bountiful amounts of nitrogen, which probably accounts for the ridiculous amount of growth in the tomatoes planted in the grow beds. We are learning, however, that in spite of the amazing growth the soil food web in the grow beds is not quite complete. There are other nutrients that don’t seem to be present, or if they are, are not accessible by the plants, such as phosphorus. We have been adding compost tea, along with fungal, archaeal, and bacterial inoculants in the hopes that these microorganisms will flourish and begin to unlock the nutrients that the plants need to thrive.

Reviving the Continuum

A Summer Landscape with Harvesters Joos de Momper the Younger

One of the greatest challenges that we face as young farmers is that the threads of knowledge that once connected us to the past have been broken. Much that once was known by our parents and our parents parents has been lost. We have to re-learn almost everything that was once known about agriculture. In some ways I feel a great sense of loss; I wish that we knew how to till and care for our land the way our ancestors did. I wish I could ask them questions, and draw on their wisdom. In other ways this is a great strength, because we are able to look at the world around us without “this is the way it’s done” blinders.

I feel an intense desire for connection—with the land, with our food, with nature, with our neighbors and friends, with our children and their children, with our ancestors. In doing things that don’t scale we are ensuring that we build and maintain those connections.

Sunflower Microgreens—Potent Packs of Protein

Naturally grown sunflower microgreens are amazing little plants. Microgreens are seed sprouts that are grown in a soil medium or hydroponically and harvested by cutting off the first starter leaves. These first tender embryonic leaves, or cotyledons, are packed with all the flavor, protein, vitamins, and nutrients of the original sunflower seed, and they’re green, crunchy, and tender.

Microgreens add zest to any salad. ((Yummly: Sunflower Sprout Salad Recipes)) Garnish microgreens on fried green tomatoes ((Edible Austin, Seasonal Plate, Summer 2009)), miso-glazed black cod ((SuperCharge! Foods)), mix them into hummus (( Sprouted Sunflower Seed Hummus)), or just snack on them throughout the day. Don’t forget to pack them into your next sandwich for an extra-healthy punch of flavor.

Are they just good to eat, or can sunflower microgreens actually help you feel better? In 2010 LiveLiving Magazine published an article recommending sprouted sunflower seeds as a remedy for depression. “Sunflower seeds are rich in the amino acid tryptophan which activates serotonin production in the body. Serotonin is one of the body’s most important neurotransmitter. When released it allows the body to relax and gives the feeling of well being.” ((LiveLiving: The Tiny Sunflower Seed is BIG in Nutrition))

A study conducted by The Journal of Agricultural and Food Chemistry found that the sprouted cotyledons of microgreens are more nutritious than mature leaves of the same plant. “Although small in size, microgreens can provide surprisingly intense flavors, vivid colors, and crisp textures and can be served as an edible garnish or a new salad ingredient.” ((Assessment of Vitamin and Carotenoid Concentrations of Emerging Food Products: Edible Microgreens
Zhenlei Xiao, Gene E. Lester, Yaguang Luo, and Qin Wang
Journal of Agricultural and Food Chemistry 2012 60 (31), 7644-7651)) The study “ultimately discovered that the microgreens contained four to 40 times more nutrients than their mature counterparts. ((Mighty Microgreens | University of Maryland College of Agriculture & Natural Resources))

Microgreens retain these amino acids and other nutrients after sprouting, and add the benefit of chlorophyl. Chlorophyll is high in magnesium, and is present in all green plants. The dark green color of sunflower microgreens is evidence of their high levels of chlorophyl. The more the better—darker color indicates more nutrient content. ((WebMD: Tiny Microgreens Packed With Nutrients))

Our First Farmer’s Market

Ragtime Ranch Family Farm debuted our first farmer’s market today! Our local HEB grocery store hosts the River Valley Farmer’s Market every wednesday in front of the store. We finally had enough produce (even after selling to all our family and friends) that we felt like we were ready to venture out to the market with our goods.

It was actually quite intimidating – what if people didn’t buy our food, what if we didn’t look as good as the other growers, what if our food isn’t as good? In the end our fears were unfounded, and we did really well – it was an encouraging turnout for our first time.

It was really exhausting. We were there for almost four hours, kids and all. The kids did amazingly, and Mimi and Papa came also, so it really was a family farm.

Our first farmer's market!

Here is a picture of what we sold.

The Greenhouse—Part 3, Finishing Up

I hesitate to say it’s finished, but the greenhouse is “mostly” finished, and we’re using it! Couldn’t have done it all without Dad’s help (and his impressive tool collection).

The end walls and screens were really hard to put up. We’ve had wind in the 20-mph range consistently all month, which made it impossible to hang fabric on the frame. Finally we had a calm day, and we were able to attach the fabric to the end wall. The end wall fabric is a single sheet of white 40% shadecloth that we doubled over to make it two layers. My dad helped me build the doors and stretch the screens. The screens on the side walls are a single roll of 84″ wide aluminum screen. The screens and the end wall fabric are fastned to the walls first with staples to hold them in place, and then also with strips of lath to provide extra holding friction.

For washing and packaging fresh produce inside the greenhouse we bought a used stainless steel sink from AAA Food Equipment in Austin. Holy cow, that place has just about everything, in any condition from brand new to completely beat up. This sink will be our washing station for fresh greens. We still need to buy a metal table for packaging, but we’ll pick that up later when it becomes an issue.

Our produce-washing sink.


Here’s a picture of the inside. We also bought those shelves at AAA. They’ll be used for microgreens. We have a wooden worktable, which you can see just to the left. The small house inside is our dry storage. It’s our old plastic mini-greenhouse. The big greenhouse is no shelter from the rain – the shadecloth just lets rain right through! The sides of the mini greenhouse can be zipped up to keep the insides dry when it rains. This is where we’ll store our supplies, seeds, and anything that needs to be kept dry.

We still have to run water and electricity (for the aquaponics) out there. But it’s serviceable  and we started our first batch of microgreens yesterday!

What’s growing this week – June 3

What a beautiful harvest this morning.


Sometimes it seems like the bugs and the weeds are taking over, and the garden is just discouraging and not so lovely. But, I just remind myself that it’s only the beginning of our journey to get our land fertile and productive. Also, bugs and weeds are there because pesticides and weed killers are not. 🙂

Spending the whole morning picking and washing veggies makes it all worth it. We have been making deliveries to several businesses around Elgin as well as selling to family and friends. Sign up on our email list if you are interested!
