Well, if you consider that the controlled 75F, 50% rh, clear skies 365 days a year do not represent Alaska in the least bit...lol....
I would say that Alaskan ops are just as suceptible to disease and other problems...
Once you allow a problem to become, it does not matter where you are...
Now... I run large res, my solution stays cool, and I had never used anything, and U had never had a problem...
But I run a perpetual harvest SOG as you may know, and I re-use my Hydroton...
Since adding Hygrozyme to my routine, I have:
Noticed a HUGE difference in rooting, when used very light (I don;t measure shit, I just put a little bit in a bowl of water) in my RW cloning cubes...
Re-used hydroton with minimal washing, and ZERO ROOT ISSUES...
Massive White Noodles escaping every pot, so white they look like they glow... with million of fyzzy hairs all over the visible roots... at harvest, my pots seem like someone just encased the hydroton in organic matter.. fresh, clean smelling roots...
I am not saying that everyone should use it...
Heck.. I am not even saying that I should use it..
But I do, and I am glad for it...
H2O2 is HAZMAT, it is ABSURDLY expenive for me to get it here.. along with radioactive materials, explosives, compressed gases...etc...
I love Al... believe me... I owe what I know and have to him...
But I have learned that the world of organics is not the complex war management that I thought it would be...
I use organics, not because I prefer the taste or potency or any of that talk...
I do it because I have become aware that if you leave the roots uncolonized, the first moment conditions allow, the bad guys will move in...
At such a time, hygrozyme is the last thing you want...
Hygrozyme will super feed the bacteria... and if you have the bad guys in you roots... Your plants will probably die...
So if you make sure that you have the good guys (H2O2 in high doses will kill them too) occupying all the real estate, and you pour in enzymes that work on converting the organic matter into bacteria food, you will ensure that if the bad guys ever show up, they will have an army of good guys to beat before moving in at all...
It's just my opinion Yak...
I don;t know shit...
You were here and kicking ass long before I ever had a harvest...
But I do believe what I said is ALSO a good way to do it... not saying at all that your isn;t a good way at all...
This is just been MY experience so far... and if I am wrong, I would love to know about it, cause I HATE to be wrong...lol....
Cheers mate...
