miracle grow soil

Discussion in 'First Time Marijuana Growers' started by cobirch2, Jun 1, 2009.

  1. i just planted my germinated seed into some miracle gro soil and it sprouted a few days ago. is there going to be any problems with the soil? i see most people advise against miracle gro. will the nutes be too much for the small plant? hopefully i will transplant it into some better soil, is going from miracle gro to another soil going to be a problem?
  2. ive grown in fox farm for awhile, i did so because i had more control on my crop and was able to flush better..

    i also have grown in miracle grow.. if funds are limited miracle is fine.. but watch nute burn, dont add anything else.

    you might wanna add some some perlite as well like 80% miracle grow and 20% perlite, that way its not all miracle grow and you get some good drainage as well.
  3. is there a certain type of soil anyone can recommend? and is drainage a problem with all soils, should i always mix with peralite or vermiculite?
  4. You may or may not have problems with the time-released ferts in Miracle Gro soil, it's not worth the chance. Here's a simple home recipe:

    4 parts 100% organic potting soil (any brand)
    3 parts sphagnum moss
    2 parts worm castings (cheap at Wally World)
    1 or more parts perlite
    1 or more parts clean sand

    Make sure none of these ingredients have added ferts (Miracle Gro peat moss and perlite actually have nutes added). Add a layer of rock to the bottom of the pot first for drainage.

    You want to be able to control your nutes -- how much, which kind, when given to the plants, ability to flush out if needed, etc. With time-released ferts you are giving up all that control.
  5. I just bought regular topsoil at walmart. The plants are looking fine. I have noticed that they haven't really grown as much as others have in the same timeframe, but my main goal right now is to NOT kill the plant/
  6. Heres a little article on MG I found a while ago if anyone's interested.

    From Organic Gardening Magazine, July/August 2000 Issue.

    Miracle-Gro is a synthetic fertilizer that contains ammonium phosphate and several other chemicals that can be toxic to your soil and plants. It is prohibited from use in certified-organic farming. Here's what soil expert Robert Parnes, Ph.D., says in his book Fertile Soil: "[Ammonium fertilizer] acidifies the soil, and thus it is probably more harmful to soil organisms than any other nitrogen fertilizer . . . . The application has to be timed carefully and placed properly to avoid burning the leaves and roots . . . . In addition, ammonium tends to inhibit the release of . . . potassium . . . Ammonium fertilizers are deliberately manufactured to be spread at high application rates in order to obtain maximum yields with no regard to adverse effects on the soil. Probably nowhere is the conflict between the mass production of food to feed the world and the preservation of the soil more obvious than in the confrontation over the use of either ammonium fertilizers or liquid ammonia."

    And there's more: long-term studies at the University of Wisconsin have shown that acidic chemical fertilizers are causing serious, permanent damage to our soils. Usually these fertilizers are also highly soluble, so they leach away and pollute our water systems, too. Soil fertility authority Garn Wallace, Ph.D., of Wallace Laboratories in El Segundo, California, points out that Miracle-Gro contains muriate of potash, which contains excess chlorine that will burn plants and inhibit the uptake of nitrogen. Dr. Wallace also warns that products such as Miracle-Gro often contain unsafe levels of zinc and copper that will be toxic to soil life.

    And if all that's not enough to convince you to avoid this stuff, consider this: you have to mix Miracle-Gro with water and apply it ever "7 to 14 days." If you opt to fertilize organically, on the other hand, all you have to do is mix a ½-inch layer of grass clippings into your beds before each crop. As the grass decomposes, it will improve your soil's texture and stimulate microbial life and help prevent disease, all while releasing plenty of nutrients to feed your plants.
