I highly doubt it. No offense. Add a pH up that breaks down or is quickly absorbed and the pH will go down. Exact same effect I'm seeing. The end flowers being highly frangible point toward none of the silicon being present in the flowers. The presence of silicon greatly diminishes the quality...

Only vaguely. I've used the same liquid silicon throughout flower and understand the negative effect it has on flowers. I have none of that effect when I use it the way I explained. Observation of the quality of the end flowers also concurs with the pH change being from silicon depletion. Douglas

Re-read what I previously posted. Liquid silicon acts as a pH UP. I mix my nutrient solution and pH it to 5.4. I then add liquid silicon (as a pH UP), until the pH is 5.8. Within 7-10 days the pH is back down to 5.4. It stops at 5.4 and begins to slowly rise as the natural pH rise from plants...

Correct. I learned what worked 'decent' 15 years ago, from other growers, and haven't broken it down. I fully plan on getting in to custom mixes to further tweak it, don't have the time/resources yet. At this point I've only made a few tweaks that help bring out better quality, and that really...

When my wife reads that statement she's going to laugh. RIU will have to wait a few months. ;) Douglas

Oh, lol. Nah, I never took a picture of the ash from mid-flower. I just know I've done it multiple times, even showed a few different people. I clip bud from a plant, chop it up small, put it in a bowl and slowly burn it. The first few hits evap the water and then the last few tun it to an...

Soft and fluffy. Just the way I like it. :) That was a tightly packed bowl of "Twista." I'm sure you've seen me post photos of it elsewhere.

Potassium would be general Lucas Formula levels, plus the GH pH Up powder. I use liquid silicon as pH up in the first flowering reservoir, from the drop in pH it's obvious there isn't any left at the end of stretch. I use pH up powder to set my pH at 5.4, then use liquid silicon to pH up to...

Mine is off-white, what color is yours? Seriously, does not matter what stage of flower, my "wet' bud easily burns to an off-white ash. I take it as sign I'm doing something wrong, if it burns to any other color. Silicon, element. Silica, combination of Silicon and Oxygen. Silicon is available...

So, would it be safe to say that the majority of the cannabis I see with black ash is from potassium and silica? I've only spent a few years using silica, I've had black ash from cannabis I overfed. Do you have links to any studies on test results for clean cannabis? I'm very curious to see...

Yes, I'd like a better label for cannabis than 'dynamic accumulator.' Cannabis has been shown to dynamically accumulate toxic levels of cadmium, from soil listed as 'cadmium safe.' Not sure where I read that though, study measuring the metal content of cannabis grown in different types of soils...

Kali Mist. Tastes like pyrethrins

Anywhere from 70% to 99% isopropyl, and only isopropyl. Leave the bottles with extra ingredients on the shelf. Yes, it's strong, only an ounce is needed per gallon. :) Douglas

Forgot to mention... Iso fumes suck for mucus membrane tissue in animals. Please use a respirator and/or excellent ventilation. Iso does damage to the body over time as well. You won't find me using it for extractions either, only food grade ethanol for that. Douglas

My pleasure. Everyone deserves clean cannabis :)

BTW, I've been infested with "Resistant" mites several times, since moving to Colorado. In my opinion and experience, there's no such thing, there are only growers who don't understand breeding cycles and properly treating plants so nothing is missed. Wiped em out, no issues, same as always...

Mother plants, which will not be having cuttings taken for a month or so, I'm willing to go with harsher methods. I've used avid once, to clear up some mites in a hurry. Safer's takes out most everything, as long as you properly break the breeding cycle. The Iso and water is very effective...

I beg to differ, at least for indoor gardens. It may not register in tests but the flavor is still there and it's nasty. Tastes like that one strain I'm unable to remember right now, only it tastes like straight chemical flowers, not the complex natural nasty flower cannabis flavor.. No need...

I make my own from from 3M furnace filters. You can get premade ones in various sizes Here's a link to a 6" PHAT filter that's HEPA rated http://www.shareasale.com/m-pr.cfm?merchantID=60409&userID=853992&productID=581938105" target="_blank Yes, that's an affiliate link. A quick search of the...

I might consider it in veg, I've tasted rosemary in the end flower before and don't care for it. I see why the mites leave it alone ;) HEPA filters on intakes and clean grow room practices go a long way toward not having these issues in the first place. Shoot for solutions which leave no...
