There are ways to increase your females from regular seed. The owner of Dutch passion has quite a bit of steps you can take to up your females. they are environmental influences mainly. weeks 2,3,4 are critical.1 increase nitrogen and lower the potassium. 2 try to keep the temps down around 68 F high temps increase males. 3 Keep your humidity up low humidity =males. 4 Use blue light hps is for flowers red light=males. 5 shortening the hours of daylight. 24/0= males males males. 15/9 or 16/8= female. Also keep the growing medium damp. but no fungus gnats. STRESS=males. no stress= females. this makes sense b/c why would you get all males sometimes, bad growing conditions=males. we all know females love to be comfortable. stay medicated. hope this gets your females up!
