Grow Tomatoes in Your Closet?

Dec 20, 2016

It's freezing outside. But living without fresh tomatoes? That's just not an acceptible condition. So this underused closet in my home is now a tomato growing closet!

This 3 x 3 closet is now fitted with reflective film, to maximize light delivery, as well as a Sun System dual watt digital ballas light fixture, which operates both High Pressure SodiHium (HPS) lamps and Metal Halide (MH) lamps. The 250 watt HPS lamp currently in the fixture provides the light spectrum necessary for good fruiting. The young vegetative seedlings, however, are grown under a "cooler" spectrum of light using high output flourescent lamps.

What are you Modern Homesteaders growing in your closet?

Indoor lettuce

Dec 18, 2016

Salad greens are one of the easiest crops you can grow both indoors and out. While lettuces are a cool season crop for those of us in southern parts of the country (hot summers, mild winters but with freezes), and you can start lettuce outdoors in the fall to grow through winter. But by the time December rools around, temperatures can get too cold for good lettuce seed germination. So seeding lettuce indoors during winter is a great way to keep your harvest growing.

To speed up germination, use a humidity dome and a seedling heat mat to get things moving. Then set your lettuce seedlings under grow lights once they germinate. High Outpot T5 flourescent lamps are great for growing lettuce and other vegetative crops.

It's important to know that lettuce seeds need light to germinate, so don't bury them under the soil when you sow them.

You can sow lettuce seeds into seed plugs or 4" pots. Always drop 2-3 seeds in just in case one or two don't germinate. Thin out extra seedlings after germination.

One of my favorite varieties? 'Black Seeded Simpson'.

Worms on the Ferns!

Sep 16, 2016

Growing plants indoors, be they low-light houseplants, or flowering and fruiting plants you're growing under plant lights, doesn't mean you're going to be free of the kinds of pests and diseases you have to deal with in the outdoor garden. In fact, it's often the assumption of new indoor gardeners that they won't have to deal with any pests, and they're often surprised when pests become one of their first challenges.


Can you see that dark colored caterpillar munching on my little ferns? Drat!!

The reality is that most plants you bring into your home probably bring a few hitchhikers along with them. A seemlingly healthy and attractive plant you purchase and bring home may all of a sudden appear less than healthy. There may also be "evidence" of the critters doing damage.


See all those little "balls"? That's frass; a nice word for pest poop!

Recently, I added some small fern plugs to my Ambienta plant grow lamps. Shortly thereafter, they didn't seem to be looking their best, and I noticed frass (poop -those little pellets you see in the photo) collecting around the bottom of the plants. Yep, they've got worms! Most likely the eggs, or even tiny caterpillars, were hitchiking on the plants, and got to work munching away and growing after I planted the ferns. Caterpillers that chew on plants tend to munch either during the night or day, then retreat back under the soil, or to the center of the plant - making it hard for you to spot them right away. So, you have to look for the frass.

Picking off the caterpillars is the first step to controlling them, as that will help remove most of the critters doing most of the immediate damage. Then, I'll spray these little ferns with a solution of Thuricide (Bt), an organic larvacide that will kill the up and coming caterpillars as they munch on the foliage.
