What causes a garden to produce 75% males??

Piss poor luck
Piss poor genetics
Stress induced anything - Overwatering , Lightcycle interuptions , Light leaks , Heat stress , anything stress related is voo doo .

I pretty much agree with what he said.

I don't have any "hard evidence" to back it up, but any genetics that are likely to produce herm plants are probably likely to produce more males. Cannabis sex genes aren't all "50/50" like some will tell you. There are definitely male genes, and varying degrees of expressed male sexuality. I'm sure just a little of the above stresses, and some others, contribute to bad sex ratios, as well as numbers of plants in the grow space... from the chemical "communication" between all the plants.

I've found that using strains that have been crossed and bred fewer than 5 crosses -not including inbreeding or back crosses- tend to produce fewer herms, or just more females.

Also, I use little grow chambers, less than a cubic meter for starts and seedlings. It keet relatively warm, humid and 24 hour lighting. I also used a standard plant food (10-15-10). On recent batches of seeds (two strains) from one breeder, I've been getting better than 85% females for the past year from seeds that did germ. I assume that the seeds that didn't sprout were males.

I really wanted some of those males, too. They just didn't show when they were hoped for.

But I don't think it's so much "luck".

I agree with both of ya ... I'm also of the opinion that a long string of inbreeding causes glitches down the road ... I never had problems with bagseeds, ever, and have finally seen all of the problems I have heard about, after buying high-dollar seeds ... in my own case, I had more problems as the prices went up :wtf:
