Outdoor Strange thing i have observed about Rain and my Outdoor Plants

[dingo]

Namvet beat me to it. PH adjiustment may play a part but can also make it swing out of range.
Lots of minerals suspended in the sky especially if no rain for some time. A good down pour washes the dust in the sky down to earth.
Plants generally benefit from this event.

I notice the same thing with my lawn , water all you like with a hose but one decent down pour is way better , I be thinking this wet season I will save a lot of rain water . :Grow & Show..:

I went to buy a water butt from the garden centre-£40! So I grabbed an old garden trash can and drilled a hole in the top-connected to a drainpipe and voila, 100ltrs of rainwater stored ready for use. I know the pH creeps up when left so I'm buying an airstone to bubble it before watering with, my plants love the stuff.

Outdoor growers will often see stems swell to 3 times their present size an inch or 2 long on some parts,after heavy rain and lightning.A sure sign of beautifully refined water from a clean atmosphere. Here's some copy n pastes with a good explanation of rain.

Plants like Nitrogen very much! And that's where the rain water comes in.Our atmosphere consists of about 21% Oxygen and 78% Nitrogen, but plants can't take it in through the atmosphere. They need nitrates. If lightning strikes through the atmosphere, it gives the oxygen and nitrogen molecules enough energy to form nitrates, which are NO3-ions. These ions react with the water and form a weak solution of nitric acid. The plants then take it up, via the water.

Hydrogen peroxide in rainwater makes it so much more effective than tap water when given to plants. With the increased levels of atmospheric pollution, however, greater amounts of H202 react with air-borne toxins and never reach the ground. To compensate for this, many farmers have been increasing crop yields by spraying them with diluted hydrogen peroxide (5 to 16 ounces of 35% mixed with 20 gallons of water per acre). You can achieve the same beneficial effect with your house plants by adding 1 ounce of 3% hydrogen peroxide (or 16 drops of 35% solution) to every quart of water you give your plants. So if you live where the atmosphere is clean ,

Thank you sir .

FYI not h2o2 sold are the same,maybe half a dozen on the market. e.g

• 3% Pharmaceutical Grade - This can be purchased at the chemist's and is used for cleaning wounds and as a general household disinfectant. But this grade can have a whole range of stabilizers, such as acetanilide, phenol, sodium stanate and tertrasodium phosphate.

Go with 35% food grade.
