Starting seeds or clones using LED grow lights is surprisingly simple. Start your seeds in your favorite medium (I like ProMix) with 30-40% perlite added to increase drainage and aeration. Depending on the seed planted, it may be beneficial to use a seedling heat mat to reduce germination time.
Whether with seed or clone, start out with the 90W or 180W light at about 18-24 inches from the top. After the first true leaves form, drop the lights to the recommended height for vegetative growth – see chart below.
