I have never seen a study on silicon effect on trichome production, if you ever recall where you saw it i would love a reference. Btw, silicon dioxide is not soluble in water, if the manufacturer lists it on a label they are being obscure. Sometimes they will list SiO2 and phosphoric acid as...

This question has some good answers already, i will just add a little more info. I hope this is informative without being too obtuse. Silicon has been demonstrated to deposit in the plant cell walls and provide structural strength as well as resistance to invasive threats like powdery mildew...

Yes, decarb them the same. It’s the same process, in both cases you are removing the same elements (a carboxyl group) and changing the acid form of the molecule to a simpler active form, CDBA to CDB, or THCA to THC.

This is one of the reasons coco coir should be pretreated with calcium nitrite, the microbial immobilization of nitrogen (the main reason is to remove the sodium). Coir is mostly lignin which is fairly stable but will provide a carbon source for microbes that will also consume N, so often coco...

Here are some points from the paper posted above, this may help put things together. There are a few categories of microbes that are of main interest in coco or other hydroponic substrates. The first is the mykorrhiza which usually comes in a blend of endo and ectos. For coco, the main species...

This link was removed by an admin, as it was a direct link to a pdf file. If you google the title you can find the document.

Just to add a little more detail, if you are in week 4 of flower thats a good time to boost the PK ratio using the Buddha Tree 9/18. The need for Phosphorus and Potassium goes up in flower development. An additional 100-200 mS ec should suffice. I dont use that specific product but i would...

You might find this literature review helpful. Look up: “Plant-Growth Promoting Rhizobacteria in Soilless Cannabis Cropping Systems: Implications for Growth Promotion and Disease Suppression”

There is evidence that late defoliation (three weeks before harvest) increases the yield and quality. As for a dark period, cannabinoid synthesis continues until the precursor synthate is used up in the plant, and continues without photosynthesis or even after chopping. I do not use the dark...

I soak the seeds overnight and then put them in damp paper towels till the radicle (root stem) appears. Then they go into solo cups fill with buffered coco. I hand water twice a day with dilute fertilizer increasing concentration each day. When they have filled the cups, they go into larger...

Good job, thanks for sharing :-)

Thanks for that. I remember reading some of that paper at some point. An interesting thing about it, their goal was “to evaluate the practicality of using chemical analysis of C. sativa products to determine their geographic origin.” The DEA funded them to see if they could trace seized...

This isnt new, but here is some analysis you may like @prankster. I am not a big fan of these products, but the data are interesting. its a tissue analysis of cannabis at veg and flower, with the theme “why do so many nutrient lines provide so much P in flower?”...

A small booster fan might not increase your outflow by much, and you cant put it on the same side of the filter as your bigger fan as that higher capacity fan will be pushing pressure against it. Is it possible to remove your led drivers outside the tent? They run pretty hot. You need some 12g...

i think you have the idea, @prankster. Since you have cited some ag resources, you can see how its done as a paste, slurry, or pourthrough. Most casual growers dont need much analysis, if using a known substrate, some balanced nutrients, and quality water. You are correct in that a soil paste...
