Miracle Grow and Miracle Grow type soils are acceptable for seeds and rooting clones, as long as it's not the 6 month formula. A little tricky with sensitive strains and newbies, but acceptable. I learned to grow cannabis using both Miracle Grow Potting Mix, and Miracle Grow All Purpose nutrients. That was the only stuff available locally except for the Supersoil, which I'd use if MG not available. (Supersoil is what I'm using at the moment)

Don't confuse compost with soil. They are two different animals, and are ph buffered differently. (compost is usually ph buffered too low for cannabis)

No addition of nutrients of any type or kind, till the 3rd or 4th internode. If it's already in the soil, so be it. But don't add more till necessary.

Keep soil moist, not wet. You can easily drown the embryo.

I use the damp paper towel method, because it works to see which seeds are healthy and viable. Rinse an unbleached paper towel, and lay it out in a food storage container with a lid. (Rubbermaid or Ziplock type) Keep the paper towel damp at all times, keep 'em in darkness, and let the taproot get about 1/8 to 1/4 inch, and carefully plant in whatever soil you are using. I plant it so the top of the seed is barely visible, but the roots are down in the soil. Carefully water 'em in. (I use a spray mister) If too aggressive with watering, it can make the seed 'migrate' or sink lower in the soil, or wash down the inside edge, (between cup and soil) never to be seen again.
Rusty Trichome Reviewed by Rusty Trichome on . Having serious problem, Need Help. I built a rubbermaid 30 gallon grow box. 6 26w 6500k CFLS for veg, with an 18/6 light time. Seeds germinate successfully, and I place them root down under 1/4 to 1/2 inch of soil. 5 days later, no sprout so I dug up seed and the root was just dead and rotted. This has happened 6 times. I have no idea what the problem is, and its getting me really down because I have read hundreds of threads and books on growing, have a great setup and know how to take care of a plant but for some reason it wont Rating: 5
