I've had this link in my favorites for awhile .I'm not sure how on the money its results play out under varying conditions;my guess is it is designed around a succesful system.but,for newbs and extreme stoners it might just be a benchmark to shoot for.I've never put it to the test,but I have put in some #'s that relate to grow's I have done and the results that the scheduler gave me were acceptable.so my opinion is it is a tool for our arsenal,it's up to us to use it properly.good luck,give it a try
