I start counting days as soon as I put moisture to a seed (wet paper towell). I know that others count differently like when the sprout breaks through the media or whatever, but my counting has always been the day I put moisture to the seed.
so far I have havested Mephisto strains from water farms between 80 and 96 days
sodk - 96 days
sodk - 96 days
grape crinkle - 80 days
sour stomper - 80 days
fantasmo express - 80 days
3 bears og - 80 days -- would have let this girl go longer, probably 95 days, but had to take her at the time
creme bubbly - 98 days
cosmic queen - 83 days
sour orange livers - 93 days
white train - 96 days
next round I am trying to reduce the cycle time with
24/0 lighting schedule
running feed pump 15 ON 45 O

instead of 24 ON -- this one I am excited about because my plants have always had a pretty slow start compared to others, and I have a feeling some of this has been due to overfeeding during early veg -- we shall see!
