i refuse to pay $189.00 for a grow light that outputs 9,600 lumins.
so i made one my self
totoal cost $1.oo for every 1000 kelvin.
at a energy out put of only 161 watt's.
i started all seed this year in 72 cell trays and will move all to 4" pot as needed some stuff will stay inside as house plants "a few dwarfs"

ecosmart fullspectrum 5ooo kelvin bulbs 100 watt equivalent
at a output of only 23 watts used per bulb
color spectrum blue 5k full daylight per bulb.
bulbs in 5k range are best for a plants blue light needs.
as i am starting seeds right now i have no need for the red and yellow light end of the color spectrum.
i may have to add them later as the plants get some flowers and blooms inside.

metal 7" vent pipe for the hood. i used this size for 1 good reason
it was .98 cents and 6" and 8" was $4.00

i had a small design change. why make 1 light for $30 when i can have two
setups for $42 here is the final setup.
each sytem has 6 bulbs at 5000 kelvin full spectrum light in the blue wave length.
and a power usage of only 138 watt's per setup.
nice llittle diy light system.
light system is only 16" x 24" total foot print area.
for 30000 total kelvin
or 9,600 lumins
of blue light for root and stock growth.
that is a very large bang for the buck in a small foot print!
plus low cost power usage. and i can reeuse most all of this sytem later in the year.
7" dryer vent from a local hardware store.
and some old 2x2 's
man 19,200 lumins is bright when you walk in the room.
i hope this may help someone along the way.

on as ide note. Light ranges in hue from ultra-violet at one end of the spectrum to infra-red at the other. Color affects plant growth and responses.
Blue light is required for photosynthesis with high levels causing dark green compact growth.
Red light affects photoperiodic responses, such as flower production and plant dormancy with high levels causing spindly growth.
Yellow light affects chlorophyll production.
A wide spectrum of light is required for healthy plant growth.
CFLS come in 2700 kevins, 3000, 4100, 5100, and 6500.
Low Kelvin bulbs, like the 2700k is for BLOOM OR FLOWERING, 6500k is for the VEG Spectrum. The others are "MID" spectrums or in between.
IF you use the MID-range bulbs (4100) then also use the 6500 and 2700s for a balanced spectrum.
(Note, the sun produces about 10,000 lumens per square foot, on a sunny mid summer day)
