What We've Learned About Growing Algae
There have been algae experiments conducted with LED Grow Master lighting for the past seven years.  We have learned a few things... Cells
produced under a specific light source need five cycles under a new light source before you can start production.  Basically, the cells of one
culture learn to use the light from their last cycle.  To use a new light source a new "acclimated" culture needs to be produced under the new light
source.  Given that most commercial cultures are grown under fluorescent lights, specifically Vita-Lights (very low energy)  one needs to produce
a new culture for LED lights.
Algae is sensitive to too much light energy and the LED light from our products is very overwhelming at first.   A light filter my be required in
the beginning to reduce the light intensity and better blend the light output. (Neutral density gray plastic window screening with a 1 mm mesh size
is a common filter.)  It is also suggested that our product be run 24/7 in the operation.
Whenever any growing parameter is changed (e.g. the culture is just coming out of maintenance, the nutrient solution is changed, light is
changed, etc.) the culture takes time to adapt to the new conditions. For research that relies on counting cell concentration to determine the
outcome of the experiment, the culture must be grown in the exponential growth phase for several days before checking the results.   We've had
great results with cultures produced using the above methods.
"The grow lights are very bright and this is what I needed for the
growth in Algae.   There are a lot of companies out there selling
products and I considered customizing my own, but after seeing
the quality of the light and the brightness and the growth that I
have I am happy to say I will be purchasing many more lights
from LED Grow  in the near future."

Growing Algae With LED Light
Many marine algae are easy to culture and are available commercially from biological supply houses.  These suppliers will often provide pamphlets
with instructions and growth media.   The National Center for Marine Algae and Microbiota (NCMA) in Maine, allows you to buy any of the over 2700
algal cultures held.  You can search their online catalog for strains and find information on isolation/collection, culturing medium recipes, and
growth conditions.
Basic Supplies:
  • Culture vessels.  (Glass or polycarbonate flasks are good choices.)  You want to be able to close the vessel but
    you don't want it sealed tight.  There needs to be gas exchange possible.   
  • Freshwater or salt water depending on the alga's natural environment.  You can make artificial seawater but it's
    much easier to use the real thing.  Better to use seawater that has sat around for awhile than to use fresh
    seawater.  Store it in the dark to "age".
  • Add Nutrients according to your supplier's recipe.
  • An autoclave or some other way to sterilize your seawater and culture flasks.
  • LGM LED Grow Lights (source of light.)
  • A controlled experiment should have a growth chamber and lighting but the basics above are enough for many
    applications and basic experiments. .
