thank you daisy and sharon
i will make myself clear
i have a coleus growing very well in a 5 litre bucket with planting soil i have some other coleuses too in other buckets same size same soil
.one bucket was sitting in another bucket with water(a closed system)
after a few days that i did not visit the plants since they where in an old neglected nursery at a school where i teach i noticed that the coleus in the double bucket was in a very good condition.......that means that it was not lacking of water and the color of the leaves where sharp and looked healthier.i also know that coleus like humidity.so it must have helped to the whole atmosphere
all i am saying it looks like it is a good solution for "go away for short time" i did not mean to grow zinnias in hydroponic culture.
by the way i tried to put last year some cut chrysanthemum flowers i got as a gift for some celebration into water in order to root them but it did not work.
i have not heard of hydrogen peroxide is it a slow release nutrition for hydroponics? i use levatit for my hydroponics
the zinnias of this year are aresult of my experiment to polinate home made style with tweesers.
so i am curious to see the result with some kind of fear(because of exess water) that i may kill them.
