    Since I'm going to be using quite a lot of water to drown the whitefly, would it be ok to boil some tap water (let it cool) and use that?

    And exactly how many days, 2? 3? should I leave them submerged?

    Thanks

    I don't know what the tap water is where you live. Typically, it is treated water and conatins a variety of things, like fluoride, chlorine, and metallic salts. That will kill many CP's, over time. Boiling the water, as in what some do for traopical fish, would evaporate the chlorine, but it would concentrate the metallic salts, making it worse for the plants. Not sure of how much water would be required, but as long as the plants are completely submerged, you won't need to use any more the water. When I was doing this, I had the equivalent of 2" pots, so I didn't need any more than a pint. Can you use distilled or rain water or stream water?

    I would submerge them for a day and then see what the results are, perhaps with a magnifying glass. If you see floating whiteflies, then it was probably sufficient. I know with aphids, a day or two was all that was needed. Keep us posted

    With regard to rain water that runs through gutters or off roofs, I tend to think that anything that is quickly running along the surface won't pick up much in the way of anything harmful. Now if it sits in a spot, I would be dubious. I have my trash barrels staged right where the rains runs off the roof and it hasn't seemed to cause any problems.

    Like jimscott metioned, the water may contain soluble salts which is a factor that harms CP's.

    By the sound of it, a de-chlorinator would only get rid of the chlorine in the water, but not the metallic salts (this is just a guess; I've never used a de-chlorinator before). The chlorine problem would be gone , but you would still have the salts to deal with(mainly).

    In my opinion, the easiest solution is just to buy deionized water at your local maket. It is VERY cheap compared to taking the time to research and spending the money to buy devices and items that help to purify your water! I'm not saying not to research how to purify water, just that it may not be worth your time.

    What is a "solar-sil"?

    simple directions (for kids). a solar still is basically a box full of water set up in such a way to collect condensation (i.e. water that has evaporated. when water evaporates it leaves behind all its impurities). it can be as simple as a plastic container full of water, with an empty cup in the middle, saran wrap over the top, and a rock over the glass.
