Just make sure it doesn't have a fertilizer component like miracle grow and maybe call the producer and bug them about salt content as well. Notes on other materials: Perlite or pulverized lava rock may be used in place of sand if it is additive free. Again, the salt in Bottled water added for flavor is negligible as a food additive but will accumulate over time and harm your plants. While these things might not kill your plants right away, some will and all they will over time. Soft water is not acceptable for the same reasons. If you must, you could buy low sodium drinking water but it's a poor risk with distilled water easy to obtain. Many bottled waters have salt added for taste.


This is not the same as bottled water and chlorine isn't the big offender, so setting a bucket of water out for 24 hours the way you might do for fish will not make it safe for your plants. Rain water will do but it is so easily contaminated you'll either need to control the harvesting process carefully or just go ahead and buy distilled water. It's cleaner than the washed sand recommended by more sources than any other component and it's non-leaching so you won't need to worry about mineral content over time. Again, no chems, additives, fertilizers or anything else. The other component I used was a very clean chemically inert black cover sand from Mosser Lee. It was just a few dollars for a 4 quart bag.

No chems, fertilzers, wetting agents, just peat moss. It's Canadian sphagnum peat that comes to them from a company in Alaska and is then packaged by L&L for resale. It doesn't state the source on the package so I called them. It's distributed through L&L Nursery Products here in California. Almost all are not immediately evident and will only show up after weeks or months of seemingly healthy growth though some chemicals that are found in certain products may kill your plants very quickly. There are differences and they usually have negative effects. Not to be confused with green moss, long fibered peat or carpet moss, all of which can be found in bags calling them "peat moss". Peat Moss- see below Sand- See below A large mixing bowl A measuring cup of some sort- I used the bottom half of a glass soda bottle.
