View attachment 1161338 Oh yeah, I've forgotten about Corybas'! Very interesting genus mate, some of the wildest looking flowers out there! Have a gander at orchidspecies.com, the best site of it's kind hands down.... Are they native to your area?
PNG is a treasure trove for reals -
They have some of the best Nepenthes spp. too! Haven't you see any for sale around your area, or online?
oooo, nice bud Hec'! How's she turning out for potency and dry aroma? ...pretty looking too...
Soil mastery continues mate -
... a very good point about perlite/pumice, makes me think it's a plot to add useless fillers to most soils!
...certainly isn't in the ground, a fact overlooked apparently,...
I think the gentle tickling with PK boosting pays big dividends with your soils, and other types like it... Hard to argue with the results and yields!
Mate how are you testing the soil pH, just curious? I know sometimes I get pots close to or at 7.0 with no signs of troubles, ditto for 6.0, but not always,.. I think the humic-fulvic and the 'crobes are the hero's here, keeping them chelated and locked away from other anions that will compound them into unavailable forms. Even if the pH isn't "spot on", this wiggle room effect comes into play!
Sea salts, again humic fulvic comes into play with the same deal,... that and many folks don't realize Cl- is a micronutrient... I've been slipping dashes of salt substitute (KCl) into my feeds...
I've been more on this side generally, but when using synthetics (like MC), I think some of my problem plants might have been getting some build-up and suffer antagonistic uptake issues,... Skunk Special got kinda bitchy about P defc., pH was OK, but fans were getting eaten too fast, all P defc. symptoms,.. I got sick of monkey'ing around and did a flush and tested run-off a few times... it was undoubtedly loaded in there, exceeding 1000ppm at first!
When I did slurry testing to compare results with the Accurate 8 vs pH meter, I tested ppm too... I uses 1:1 soil/water too, I wanted less dilution for this... The ppm's were both under 350,.... So, I may do a pre-bloom flush, just to reset the table in there before I go to the mainly organic bloom nute regime (Root Organics Terp Tea is nice stuff, BTW)...
I'll take a cuppa!
