How to Grow Marijuana Everything You Need to Know
Much of cannabis cultivation info is left-over from dirt, which is tricky stuff.
You never know exactly what's in there.
With water you can be sure: An osmotic 'black hole' when pure,
an engineered ideal mix when good nutes are added correctly.
I've
never bought or used cal/mag. Ever
GH or H&G base nutes in city tap water. No amendments.
With aero, total ppm should not exceed 1000. If with RO or rain water - 800 max. Do this and you will have no problems to blame on fertilizer. There are other factors in a garden of more significance than the FN nutes.
My first successful grow was in 20 oz plastic cups with one third each of peat moss, perlite, and vermiculite. I watered to excess twice daily with tap water and one quarter teaspoon Peters all purpose 20-20-20. 25 years later, I now use pure coir and either Lucas (GH) or H&G Cocos. I try additives, and enjoy no advantage from them yet. Hope springs eternal, and I try yet another, for naught.
Rutgers University turned down the offer to grow for the state of NJ.
what dumb asses. they could have experimented with all kinds of strains and maybe discover somthin new about MJ not to mention money raised for the school. I am amazed at the people who get these opportunities and don't see it.
Does Rutgers receive 'research' money from big pharma? Of course they do, and that stops before cannabis is promoted by a major institution. The DEA is also controlled by the money of big business, so Rutgers accepts the status quo. Blame DuPont or Monsantos, not Rutgers. 'Energy'(oil) companys also have vested interest in stifling cannabis. All of these industries buy politicians who know how to stay bought, and earn their bribes.
