Beating the Heat


Here it is, June on the Gulf Coast. After 3 days of storms, the heat and humidity has settled in with a vengeance. It is just steamy and miserable outside and the mosquitoes are rampant. I’m still gardening and we continue to harvest summer squash, chili peppers, sweet peppers, currant tomatoes and blackberries…and tomatillos, hundreds of tomatillos. Our bees have settled in and instead of hitting the herb garden, they have been working the tomatillo bed. Our plants are loaded with fruits in various stages of ripeness. This is the biggest tomatillo harvest we’ve ever had. So, what are we doing with so many tomatillos? Improvising! Last night, I made a simple batch of salsa verde that only took minutes. The recipe is below.

My garden is my passion, but as the summer heats up, it will be harder and harder to work outside. Sunburn and heatstroke are very real worries in areas like this where the temperatures soar over 100°F and we have no shade trees. The only gardening done is early in the morning or late in the evening. Many of our crops stop producing during the hottest part of summer and start up again as the weather cools in the fall. Unfortunately, we still want our fresh produce, particularly salad greens and herbs. To that end, we have begun using a hydroponic system inside the house.

We began researching hydroponics last year. Salad greens are a touchy crop to grow here as our early spring temperatures can cause lettuce and spinach to bolt. It can be 40°F on Tuesday and 80°F on Wednesday. Since we love our fresh mesclun, spinach and lettuce, we decided to find a way to give them more optimal growing conditions. Hydroponics seemed to be an acceptable answer.

My husband used PVC pipe to create a simple flood and drain system for hydroponic growing. He cut 4 tubes approximately 4 feet long and cut 5 holes in each of them. He fitted them with end caps that he had drilled holes in and attached them with rubber tubing. It all connects to a reservoir underneath the system which contains the water/nutrient system and the pump that sends the solution up through the tubing to the plants, and an air pump that keeps the solution oxygenated. We hung a grow light over it. Once the system was built, the experimentation began.

First, we tried peas, but the system was simply too wet for them. They rotted. Next, we tried spinach, but apparently, we had some bad seeds because we couldn’t even get them to germinate. Finally, we tried sweet basil. We hit a homerun with that one. The seeds sprouted and we put the tiny seedlings in the little net cups and inserted them into the holes. The pump was set on a timer to flood the tubes with water periodically throughout the day. We turned on the grow light in the morning and turned it off at night. When we changed the nutrient/water solution, we used that to water our outside gardens and pots. All of our plants, inside and outside, were nice and healthy.
