Joel and cnd411 i would like to answer you "Yes but under which conditions?". On the strainbase of overgrow, i saw a yield of AK47 of more than one gramm per light watt used. OK, but what was the nute concentration, the boosters, and the amount of CO2 spent. I can tell you that under normal conditions, no CO2, 600 W HPS Hortilux, GH Flora series and no boosters, i got 11 ounces of dry buds with 4 plants of Skunk Special from female seeds. I can't get that result under the same conditions with AK47 or Sensi Skunk#1. The same with the pics of AK47 on the serious seeds website. What the cost of theses awesome buds ? Wattage, nutes, CO2, exhaust, ...
Skunk Special from female seeds is the most interesting strain i ever grown as for potency and yield, and ease of growth.
