One of the oldest strains I grow is only in regular seeds. I forget just how wonderful this strain can be. The most special thing is these regular seeds usually run around 80% female. I have seen other strains bred by the same breeder that do it also. I have also run across this with major breeders also. I have had 5 packs of TGA seeds produce 4 females. Pretty sure it is in how the seeds are made. Healthy plants produce healthy seeds. Keeping a plant well fed all the way through the seed making process might be the key........................ I am not sure if people realize that the male female ratio's of regular seeds are probably a lot better then they think. Another key when growing regular strains is strains that show sex early. Some strains show sex under 20hrs of light. The strain that got me on this subject had some plants show sex at around 6" tall. This can save time and soil when you can sex them early before repotting into flowering pots. Now they are 12" and all have shown sex. 7 of the 9 were female............. Contacting the breeders directly can get you info on how early their strains will show sex. They may also give you a estimate of percentages. Though even if they are around 80% they may not say so because you just never know. Though rare some packs could end up with more males then females.......Don't let a couple males keep you from growing the best. While there are tons of great female only strains. All the true champions come from regular seeds. Why grow someone else's great pheno when you can find your own.
