Hash Plant’, ‘Afghani’, ‘Hindu Kush’, etc., are great varieties that finish mid- to late-August. The yield and potency are quite high, but the fragrance is high, too! These strains are for experienced growers. They need lots of intense sunlight and must be watered from below, not from above with rain. These varieties start to bud when the days are long and the sunlight is intense. The buds fatten up quickly on plants with a short, squat growth habit. Rain followed by hot sunny days can foster mold, which could decimate the crop in a short time. Leaf has seen dried, cured buds the size of softballs that were packed with mold. They were thrown away. To avoid mold problems, he suggests harvesting when about 10 percent of the pistils have died back. Even heavy dew can cause a moldy disaster! Leaf loves ‘Hash Plant’. ‘Early Pearl’, ‘Early Queen’, ‘Early Riser’, etc., ‘Manitoba Poison’, and similar strains finish from late-August to early-September at latitude 49° north. They are potent and yield a little better than the plants listed above. They grow from six to nine feet (1.8-2.7 m) tall and are quite bushy. Most of these strains are mold resistant and easy to grow–excellent choices for novices or growers with little time to look after their plants. ‘Mighty Mite’, ‘Durban Poison’, ‘Jack Herer’, etc., finish mid- to late-September. The yield and potency are very good, and the odor is not too intense. All the plants grow a huge, dominant main cola with several large terminal buds on main branches. They may need trellising to avoid broken branches. Topping appears to increase yield. These strains are fairly low-maintenance, but the more love you give, the more they return. These plants grow well if left alone until mid-September and have a good harvest as long as they do not dry out or fall over.

I don't ha e experience with these strains, I was just quoting what I had read. I thought it was good info. There's many factors involved though, saying that I'm not doubting your ability or calling you a liar I just want to make that clear. I've red conflicting information here, there, and everywhere. I do a lot of reading, about everything lol
