Growco is here to help you garden where the sun
Many of us live in areas where gardening
outdoors in the fall/winter months is simply not possible.
But, if you love to garden, there's no reason why you
shouldn't keep it up through the winter months.
Growco has been in the business of helping
our customers set up indoor gardens for well over ten
years now, and we've watched horticultural lighting evolve
plenty in that time. It all started out with standard
fluorescent tube fixtures, and now we're selling space age
Back in the old fluorescent
days, yield was sparse because fluorescent tubes have always
been lacking in "penetration" capability. But, the newest
generation of fluorescent fixtures, T5's have almost twice the
output of the old fluorescent tube lights.
We've found that our T5 fixtures
are great for all vegetative growth. With the "cool" spectrum
bulbs, they're all you'll need for small plants like leafy greens
and herbs. For larger plants, T5's are the best quality light to
start your vegetative growth before switching to HID lighting for
fruiting/flowering. We recommend using T5's to get your plants up to
8-12" in height before switching to HID's. For other plants like
orchids or bonsai trees, T5's are perfect. Use the "cool" bulbs
(6500k) for vegetative growth, and the "warm" (2700k) bulbs for
flowering, or mix the two spectrums for full-spectrum output. Find
those types of grow lights
We recommend HID lighting for larger plants
like vegetables and other big flowering plants, and during the
fruiting/flowering stages of growth. HID lighting is superior to
fluorescent lighting in that it has the ability to "penetrate" the
plants canopy, and cover a larger area. This higher intensity light
will get through the canopy and down to the lowest leaves on your
plants. What this means to you is a healthier and seriously more
productive garden. In our HID selection, we've got two types of
light- metal halide (MH), and high pressure sodium (HPS). Most of
the fixtures we sell will run either MH, or HPS lights as you choose
just by switching bulbs.
Metal Halide (MH) lights are centered toward
the "cooler" end of the spectrum (although there are
and High Pressure Sodium (HPS) lights are toward the "warm" end
of the spectrum.
MH light is generally a white/blue (cool)
spectrum of light, much like the bright light of spring and
early summer, and will achieve much better compact
vegetative growth than HPS (fatter stronger stems, and broader
leaves). If you're growing large plants (over 3' tall), MH is
the best choice for the rest of your vegetative growth phase
after you stop using the T5's for beginning vegetative growth.
HPS lights are the closest you can get to
natural outdoor summer light quality. For optimal
fruiting/flowering results, you simply can't beat HPS lighting!
HPS is more centered toward the yellow/orange (warm) end of the
spectrum, more like the filtered light of late summer to early
fall. When a plant "see's" this warm light, it triggers a
flowering response in the plant, and causes a hormonal output to
take place that forces the plant to produce it's fruit or
In considering the correct wattage for your area,
keep in mind that although higher wattage will absolutely equate to
bigger yields, it also means higher energy consumption and more heat
output to deal with. First and foremost, when you're creating an
indoor garden area, you've got to be able to control your
atmosphere. This means maintaining a "warm summer day" at all
times for the plants. Keep this in mind when you're choosing the
correct wattage. The sizing chart we've provided below is also a
helpful guide for deciding on the correct wattage for your garden. A
state-of-the-art garden area often uses sealed up, ducted reflectors
to effectively remove the light heat from the garden area. We offer
a huge selection of ducted reflectors to best meet the needs of your
particular garden area. You can find those
LED lighting is the newest form of horticultural
lighting on the market. We've been experimenting with LED's
since we could get our hands on the first one to hit the market.
What we've found is that LED lighting is perfect for some garden
areas. The growth you'll experience under LED lighting is very nice
compact development, but kind of slow. The advantages to using LED's
is that there is very little electrical usage, and almost no heat to
deal with. If you've got a very small space that can't be ducted
to remove heat, LED's may be the best answer for you. Others may
find that when used as a supplementary light source in addition to
fluorescent or HID lighting, LED's will improve the results from
your garden without adding any heat or additional power usage.
Adding supplementary LED's to the garden perimeter will cause
additional flowers to develop, where there may have been none
before. As either supplementary lighting, or stand-alone lighting,
LED's have found their place in the indoor garden! Check out LED
