New Grower Male and Female Is it predetermened in the genes.

Is seed sex predetermined by genetics?

Just cast myt vote.... I said I think environmental factors can influence the sex, but I'm assuming that we're simply defining a 'male' as any plant with balls - ie male type flowers - and no pistils/female-type flowers.

I spent many years in Central Asia, in an area where wild ruderalis cannabis grows everywhere. I noticed that the plants that grew between tiny cracks in the pavement and places like that tended to be male more often than not. They'd grow to like, six inches tall and then start spraying pollen everywhere. The females were more concentrated in flower beds and other places with deep rich soil (of course there were males there too). I'm wondering whether this was an example of the environment causing those little guys to flower as males because the soil was just too poor to support the formation of seeds.

This is just supposition though. I just noticed this casually over the course of a few years as I was walking about the city doing my stuff.
 
Thanks for voting. That is an interesting observation. Never thought about soil conditions having an effect. If everything else can make an effect on the sex I guess soil conditions could be viable also.

I agree with the statement. That real people on a sight like this is so valuable for their observations. What would we be if we couldn't read the test reports on the different strains. Real smoke tests from real growers I read them all. Seed breeders write ups of the seeds they are selling such total bullshit.


Real life observations like this mean so much more to me than a paragraph or 2 in a text book.Thanks for sharing.
 
Good luck with your seeds. Sometimes I just get too carried away when I comment on the seed companies. I am sure many are honest and forthcomeing. I just hate it when I see report after report saying strength 10, 24% thc. ONe hti and it sends you into mind blowing stone that lasts all day ong.


I'll keep this in mind when I do the packaging on my Auto Majestics. No BS Just the facts mame, as ol Joe Friday used to say..........
 
Good luck to you with your breeding.
 
Didn't do a bud test night. Had friends over and decided ding the test is sokething I should do either alone or with my wife. Be back tomorrow with the write up for the next test which is Herijuana out of male Wild Kentucky and female Petrolia Head Stash. I totally know nothing about any of them. Amyone out there got a clue?
 
First, Nelson please let me know how the herijuana is. I'm interested in trying it.
Now back to the topic at hand. The Strawdog article is pretty good. I don't agree with all that he says but I do agree with most. Prior to reading the original Dutch Passion/Jorge Cervantes article I germinated 675 seeds this winter. I started with twist cfl over a float bed. We started tobacco this way and its how I start marijuana in bulk. I got 440 females although its not a good example. After seeds germinated in the trays they were given 1 week inside and then the trays were taken to the greenhouse. Upon my introduction to autoflowers I read all I could find. I began running my lights 20/4 because of what was said by many. I ran them directly under hps which again seemed popular. The temperatures I couldn't control with much accuracy just because. Humidity couldn't be controlled much. Out of 50 seeds 38 turned male. This was very discouraging. I then ran across the dp article. Since I'd already had such shitty results using other peoples methods I decided to give their theory a shot. Batch 1 of 20 seeds was about a 60/40 split. Temps were still in excess of 90-95, humidity was in my favor, I used high nitrogen food, light cycle was 18/6 and done under 500 w of metal halide.
Batch 2. Was 20 seeds. Again using high nitrogen food during vegetation. Light cycle cut to 17.5 on using thee same mh. Ventilation and cooling were increased. Humidity domes(homemade) of course were used. The results for that group went 17/3 in favor of females.
Batch 3 of 20 seeds using the same method as above with even more cooling and a 30 minute drop in light produced 18 females.
Since then I germinate in smaller batches just because of room.
When I order seeds now and I receive them my first goal is to attain a male. I can do this with about 95% accuracy. My method is simple. I germinate 1 seed in a 16 oz. Drinking cup. they are all dipped in fulvic acid just prior to going in the dirt. I make sure the temperature during germination never exceeds 80. Once the seed sprouts I squirt it a couple times with bloom fertilizer to increase the potassium. It then goes under red cfls in a 2x2x2 cubby hole section of a closet and the door is shut. Lights run 24/7, there's no airflow. I say I can do it with 95% accuracy but everything I've done in this manner becomes a male.
After achieving my male I then go to work with the females. I do exactly as I outlined above and out of what would typically be 9 remaining seeds ill get my 8-9 females. I have absolutely no need to bullshit ya. What you do is your business, but as a fellow grower I kind of feel the need to make it known just so its known. Here's the deal though...you can do the above methods half ass and you'll still get your 60/40 split. If you believe that's all that's possible then its prolly all ya gonna get. OR you can place some faith in someones ideas whether you agree or not. Do exactly as they say and in a couple trys achieve superior ratio results. These methods have worked on every conceivable type of mj plant and done correctly the results are pretty much the same. One thing I would like to say is that it appears as though of you can achieve 4 of the five criteria you can still get good results. So for those that wish or think that 20 hours of light is the only way to go you should still do ok assuming everything else is in check. peace

and then you are using these males for breeding?
