CFLs Are Good Grow Lights for Living Spaces

October 23, 2018

The light produced by CFLs is acceptable in your open living spaces. CFLs are a good lighting solution for smaller spaces, small grow tents, and areas where you do not want too much heat buildup.

Most CFLs are full spectrum, leaning to the cooler side, but you can also find them with a warmer Kelvin color-temperature rating.

Narrow Grow Light Spectrum With LEDs

October 22, 2018

Light-emitting diode (LED) grow-light technology allows you to narrow the spectrum of light you provide to just one color, referred to as nanometer specific light. You can purchase LED grow lamps that emit only a red spectrum of light or a blue spectrum of light (as well as other individual colors, such as orange and green).

This LED lamp emits only blue and red nanometer specific light.

While you can use red and blue light exclusively and successfully, only a few species of plants are able to grow well under only red or blue light indefinitely.

Seeding Turnips

October 22, 2018

Root crops (carrots, turnips, beets, radishes) and large- seeded crops (beans, broad beans, squash, corn) do not transplant well, so you should sow them directly into the garden or final growing container.

In this case, the days-to-harvest number on the seed packet is the time it will take to harvest from the date of germination. Plant these crops when indoor or outdoor temperatures are ideal.

LED Grow Lights Run Quietly

October 21, 2018

Large LED rigs run relatively quietly (although they do make noise), might not use as much electricity as HID lamps, may produce less heat (they claim to convert more of the energy into light), and provide a large footprint of lighted growing area.

These features make true full-spectrum LED fixtures useful for growing in an open living space where you don’t want pink- or purple-colored light. Be prepared for these fixtures to make some noise and carry a heftier price tag than other LEDs.

Grow Vanda Orchids

October 20, 2018

There are many different types of orchids you can grow indoors. Vanda orchids are particularly beautiful, but can sometimes be a little challenging for new orchid keepers.

PC: Leslie F. Halleck

Vanda orchids require high humidity in order to thrive. Wetting the growing medium—as opposed to directly watering roots like you might with terrestrial-type plants—increases the humidity around the root zone and leaves. Epiphytic types with aerial roots will appreciate a regular misting of foliage and roots versus heavy watering at the root zone.

Humidity Dome Vent for Seedlings

October 19, 2018

It is important to increase humidity around your seeds as they are germinating. The easiest way to accomplish this is to place a humidity dome on top of your seed trays. A good humidity dome comes with a vent you can open and close to conserve or vent moisture and heat.

PC: Leslie F. Halleck

Remove the dome once all your seedlings have germinated and begin to produce green growth. If you keep it on too long, fungal diseases or rot could set in. While young seedlings need to remain moist, excess moisture can promote damping off disease, which causes seedlings to rot at the soil line and topple over. Too much humidity also encourages powdery mildew on young seedlings and transplants.

What are Chives?

October 18, 2018

Chives are resilient, easy-to-grow perennial herbs. They are small bulbs that belong to the onion family and serve as ornamental blooming perennials.

PC: Leslie F. Halleck

After three years in the garden, you may need to divide your clump or container of chives. In the garden, plants can spread aggressively by seed. Harvest chives by snipping off leaves at the base, then chopping up to use fresh or cooked in your favorite dishes.

Do LED Grow Lights Cost More?

October 17, 2018

As LED technology advances, these types of lamps will likely outpace other types of traditional grow lamps in light delivery and energy efficiency. But currently, LED grow lamps do tend to be more expensive than their grow lighting counterparts.

LED grow-lighting options are quickly becoming more creative and versatile.
PC: Homestead Gardens

As with any evolving technology, part of the bigger price you pay now (with perhaps less efficacy) is an investment in future advancement and efficiency.
