    Default Not your average watering question

    I posted some of this as a reply on another board. I'm afraid it will get lost so I'm posting it here as well. When I water/fertilize(W/MSU) I place the plants in a big tub. I then I flush with the water/MSU mixture. After a few gallons I refill the milk jugs and do some more plants, and so on and so on until they are all watered. I use the same process when flushing the plants with plain RW. Whatever water/fertilizer is left goes to the other houseplants, or to fill the humidity trays? Will be detrimental to the health of my orchids?

    I don't use fertiliser, but I do use water from my fish tanks (made up of half RO water and half tap) to water my orchids (fairly basic Phals, paphs and catts) which most definintely has nitrates in it as well as other minerals. I dunk them and soak them in the fish water in individual planters/ vases then empty and don't actually flush. I do however try to flush them every coupl of months or so, just in case. So far all of my plants are doing well and seem to like this treatment.

    The only thing I would say is that i was slightly confused and possibly misunderstood what you wrote in your post - do you mean that you flush with water/ MSU mixture collecting and reusing this to flush your other plants? if so, then this might cause problems as either disease could be transmitted, or the plants flushed at the end would be receiving more and more concentrated minerals in the water used for the flushing.

    I am aware that some orchids are more sensitive than others to the water quality and to the salts and minerals in the medium. Perhaps if you told us what type of orchids you keep, it may help people give a more considered opinion to your question, as what is acceptable for some orchids, may really not suit other types of orchids.
    Hope this helps for a start.

    I guess that pretty sums it up. After the 1st batch gets watered and drained, I get the 2nd batch and so on. After I've used 4-5 gallons I refill the bottles and start again. For all of my 50 some orchids I will use approx 8 gallons of liquid. When I'm done, I'm usually left with 6-7 gallons of used water(if you will). I then take the resulting used water and use it on the rest of the houseplants. Whats left after that gets poured in the yard.

    I'm primarily maintaining the health of a few Catts,a Vanda,a couple of Big Box Dendrobiums, the usual suspects of Phalaenopsis. There are a also a few Onconiums that I got after they bloomed for a couple of bucks and a Cirrhopetalum which I'm excited to see bloom.

    Be careful sharing water, I broke this rule and lost a ton of plants to black rot. One new plant, from a trusted source, came with a contagious disease and I did the rest. I now am very careful with watering and I'm using physan 20 to disinfect like I should. It was heartbreaking to watch my plants wither and die.

    Thanks,
    Enough said. Should I be using the physan?

    Physan used every so often as a precaution is fine. I think the sharing of the water/fert is fine as long as you keep it to healthy, established plants in your collection. Water the newer orchids on their own mix until you feel they have past 'quarantine' time.
