Repot!? Does that have something to do with marijuana!?

Re the microbial situation. Could make sense that microbial action is accelerated by fertiliser.
That's an absolute fact. Nitrogen plus a carbon source causes the colony to explode.
The petrochem company I work for used a high-N / olive oil emulsion to remediate some of the Exxon Vadez spill. The spray accelerated the native bacterial growth, and when the olive oil was gone, they went to work on the spill. All traces were gone within 6 weeks.

No problem with that, but why is the decomposed bark mix so detrimental? Sometimes it is and sometimes its not, but why?
I would be pleased to know the pH of RO or rain water in contact with a decomposed bark.No problem with that, but why is the decomposed bark mix so detrimental? Sometimes it is and sometimes its not, but why?
Wonderful if the native bacteria was able to clean up oil spills btw.
That's a different conclusion from what I got (especially from fig 1).
-Moss with no plant or fert stayed at average of 5.0 su (after initial drop to ~ 4.0).
-Moss with plant but 0 fert went from 5.0 to leveling off average of between 3.5 to 4.0
-Moss with no plant but fert added immediately went to pH 3.8 and eventually crept down to ~ 3.5 (almost no change just constantly low).
-Moss +plant +feed started at the same spot as the fed only pot (about 3.8) and eventually declined to about ~3.0.
So over 1 pH s.u drop just adding N in the first place, but plants contributed another 1s.u drop to the fed and unfed condition.
I believe N rate was 200ppm in these trials and the trial length was only 30 weeks. Peak lows by 12-15 weeks after which seemed either leveling off or recovery.
Lance said lack of air. But is it really a issue if we reduce the watering frequency? Well if it is broken down to small size like Clay, then I can see that lack of air could be a problem. But maybe somewhat decayed media provide more stable environment (with regard to soil water potential/osmotic pressure).
Can you get an acurate measure of media ph by collecting the ran through water or fertilizer mix from the bottom of the pot?
Bjorn, you cannot increase your watering frequency because a decaying substrate take a longer time to becomes dry. If you increase the frequency the substrate becomes soggy and the air circulation chances in the substrate becomes null.Naoki, I see that you understand what I am after. When it comes to moisture etc. we all know that many plants, typically phrags but also some paphs are standing with their roots more or less into flowing water or more common, water seepage. So moisture/wetness is not the problem. Most likely the main problem is the availability of oxygen dissolved in the water, and of course if the "mud" is caused by bacteria consuming available oxygen, then your roots will suffer. Of course, such an environment may be typical for most broken down mixes and if oxygen is not alloewd in the pot, well, then the roots perish. In such a case it might perhaps be a better option to increaser watering frequency in order to refill with fresh, oxygenated water.
This what I use and see my table #23 this thread.Well, my assumption is that low fertiliser in every watering with relative high Ca to K is good for the logivety of the compost, -or the roots actually.
