1. Mature the plant around the 36th day, you can do this by changing the light cycle to fourteen hrs, the downfall of this is that the marijuana plant will be smaller. When doing this you should do so gradually until you hit the fourteen hr mark.
2. Stop any watering as the marijuana plants begin, this will make the resing goto the flowers, this will achieve s small increase in the resin.
3. Using a sunlamp on the plants when they start to delvlop flowering stocks.
4. By snipping off the flower at the joint of the plant, this will cause a new flower in 2 weeks or so. Repeated a couple times will give you more flowers then before.
5. By spraying the plant with "ethel" early on in the growing stage, this has been proven to produce a majority of female plants, by doing this you will also seep up the flowering which can happen in two weeks.
6. Colchicine, which is a substance to change the growth, hard to find and expensive. To use this get a presoak solution going with water and 10% colchicine. Doing this will cause a lot of the seeds to die and be unusable However the ones that do come up will be polyploid's, the weed thats comes out of this

Post in here your tips and tricks

Nice thread Rollitup, the tips will be put to vigorous use. Just one little thing is bugging me... ethel. I read about this stuff before I started growing, but I read it as ETHREL, must I have been drinking too much mead?

I actually asked for it in my local grow shop and they had never heard of it. Surely if they had heard of it they would have realised I had made a mistake?

Do some asking around, the grow shop down here has it, Colchicine is the hard one to find and you need to find a lab to get it off of.
