    Default Rainwater?

    I read a lot of people saying they use rainwater on their orchids. Am I missing something? How on Earth does one collect enough rain water to nourish their orchids? Is there some fancy system that people are using to gather and store it by the gallon every time it rains?

    If you live in your own house and collect what falls on the roof there can be a substantial amount of water. And if you live in a "rain country" and not in a desert there is even more

    I still don't see how collecting residual water from roof tops could possibly be enough to water an entire orchid collection. Orchids need to be thoroughly drenched, not sparingly flicked with 2" inches of rainwater collected.

    ok sandtiger...today it rained from 4a.m. to 10a.m and many parts of my country flooded..this is torrential rainfall....now most of our roofs are corrugated steel or galvanised zinc sheets.....with PVC guttering systems.....now 2 inches of rainfall doesnt sound like much but on a roof surface area funneled into a gutter shoot...that can fill barrels of water in an hours time.......if a greenhouse/shadehouse/shed is designed specifically for rainfall collection this can be easily achieved.....and beleev me....ull get water more than u can ever use....we have a rainy season......6 months it rains frequently...then the dry season it rains stilll but more irregularly...not bone dry...and some weeks i never water..orchids outside....nature takes its course

    Everything depends on the amount of rainfall, and Texas is not known for rain.

    In Sweden it rains about 500 mm during a year (on the low side), every square meter of roof will then give 500 liter of water a year. A greenhouse of 15 square meter give 7500 liter of water. A small typical normal living house has about 100 square meter roof, that is 50000 liter of water. If you own a barn you start getting olympic swimming pools of water every year.

    Remember now that Sweden is NOT a heavy rain country even if we constantly complain about bad weather!

    Most of the US east coast all the way down to Florida get well above 1000 mm yearly and the north of the US west coast get more than 2000 mm . Do the math and you will find that you get more than enough water even for a pretty large orchid collection.

    One good rainfall for about 20 minutes fills my 60 gallon barrel, but I live in florida. A full barrel will last almost a week in summer to water orchids.

    I too, have a 60 gallon barrell (black, plastic, garbage can with cover). I do not have a pump so I take it out of the barrell and filter it for any sediment which might have come off the roof. This is put into a 5 gal sprayer (I only use 2 gal at a time, because I cannot lift 5 gal!!!). strapped to my back, and spray the orchids. I usually have to fill up twice at each watering because of the quantity of plants I have. I do not use rain water every watering. Using rain water for fertilising makes a great difference. I also use it when applying systemic fungicides or insecticides.
    Save some and try it you will see the difference.

    i grew up in an old country house in michigan, and we had a cistern built under the house. although in the 60's the house was hooked up to the town's water lines, we were still able to use that water if needed by turning the pump on (especially useful when the pipes were frozen in winter, but the underground system was useable). before then, that was the home's only source of water. we didn't use it much, and sometimes the thing would overflow! however, be careful, in some states it is ILLEGAL to collect the rainwater, as some american states have laid claim to the water that falls on your roof and property. using it can bring you a very stiff fine and they require you to dismantle any collection system. the states claim that using the rain is 'diverting' natural water resources and causes water shortages in their water system, but in reality, they are simply not making money off people who use free rain water. studies have shown that people using rainwater relieve a burden on the supply, as opposed to taking away water from the supply, as most rainwater runoff does not get funneled into their water system. a man was just jailed in oregon for using rain water. here in california, even using solar power is coming under fire, they have made it so that you HAVE to sell any unused electricy you generate back to the power company at a very low price. people installing solar systems are now required to hook them up to the power grid at their own expense. people who already have them have to go and pay to have their systems connected to the power company. this is because people lobbied the state to enforce this, since the power companies don't want us to go solar they are making it as difficult as possible.
