In the "Soilless Mix." graphic of Naoki the phosphorus behavior is strange .. phosphorus is assorbed better with very low pH? It is the opposite then in the graphic reported by Stone. Isn't it?

Don't you think that 34 ppm of Sodium are too much?

Wonderful.. please tell us something about growing tips thank you

The largest differences are in Boron, Fe, Cu ...

But if I use the same commercially available complete fertilizer at 50 ppm N I underdose micros?

Thank you Gonewild but the problem is that on complete fertilizer label there are the micronutrients ratios but the their ppm in the final solution depend by how much fertlizer I have used.... For 100 ppm of N I have x ppm of Boron (for istance) and for 200 ppm of N I have 2X ppm of Boron ...

Is there something written about the range suggested for each microelement in solution? A minimum and a maximum level? Irrigation water without any fertilizer should have the same amount of microelements?

Dear Orchid friends, The ratio of macro and microelements in a nutrient solution must be costant? In other words a solution with 100 ppm of N must have more microelements of a solution with 60 ppm of N? Or should be better if microelements were in the same amount in both solutions? Our hobby is...

OK, Thank you

But I Know that EC meter is not very usefull for organic fertilizer ....

It is very interesting that there are so different opinions about Na level in irrigation water: Below 75 ppm, the best would be 0 ppm........ Perhaps a good idea is that of Myxodex ? In deciding the right level of K is important the NH4+ level anda Na level too?

Irrigation water

How much compost do you use to make the tea?

I have read that for crops the toxic water level of Sodium (Na) is about 50-60 ppm. Is it tha same for orchids too? In an old article of Neptune, in "Orchids" AOS magazine, I remember that the adviced level of Na was below 10 ppm. What do you think about it? Thank you

I have this problem. Pill bugs are dangerous if they are a lot. I have found effective flow the pots with piretroids. The first time pill bugs come to the surface and, after 20 minutes, then I flow again. It is effective.
