General Hydroponics Armor SI for Gardening, 32-Ounce

I've grown with and without this product to compare. This does seem to promote strong thicker trunk/branch development, along with faster recovering time after pruning. Seems to give plants a higher tolerance to heat as well. Just using the recommended dosage on the bottle and slowly ramping up as the plant grows. A little goes a long way. I would say this is a good value for the money.

Awesome stuff, reduced the risk of powdery mildew on my cannabis plants and increased the resistance to insect damage and temperature related stress. Much more stable than ProTekt, which crystallized bad around the lid. Plenty of potassium to act as a bloom booster as well. Highly recommended. I used at half strength during early veg and boosted to full strength during growth spurts and into flowering.

Good

Great products gh are.

First-time user, and I believe I am seeing some substantial results in terms of plant structure and sturdiness. Full disclosure - this is my second personal cannabis grow, and improved knowledge and training practices since my first grow may also have contributed to my success, so take this with a grain of salt. I have been applying 1ml per litre and adding the completed mix to both my DWC (Deep Water Culture) hydroponic systems as well as my Fabric Pot outdoor plants. Plant stems and stalks are approximately triple the strength/thickness of my previous grow, and there is a sort of durability to the leaves that was not present in my earlier grows, feeling thicker and possibly larger (hard to attribute directly to silica since I am training these plants - LST - Low Stress Training - differently than my last grow, but seems likely). There is almost a slight 'waxiness'to some of the larger, more developed leaves. They seem to be able to handle heat stress very well, where my first grow had issues now and then under standard LED lighting, these plants can take the pressure of newer 2000w lights with COBs and additional supplemental lighting without issue. In short, there is probably triple the intensity of light in my tent now than last time and there is virtually no sign of heat-stress. On the negative side, over-feeding silica seems to have a detrimental side-effect: branches may snap easier under pressure if too much is applied. I doubled the silica feed on one my plants to test the results of silica feeding. This is the only plant i overfed, and when employing LST (Low Stress Training - bending and shaping the plant into a desired shape - in my case a flat bush) the plant became harder to bend, and inevitably easier to break. This plant was for all intents and purposes the same as the others in terms of size and shape, except of a slightly different strain. Again, take that with a grain of salt. The branches could not bend easily and I ended up breaking a large branch at the base. I repaired that and moved on to the next, but not before easily snapping off another fan leaf, also at the base. I tried again to work on another branch but felt resistance and now knew what came next. I believe that the over-feeding of silica is causing the branches to become too rigid and too heavy to properly support themselves. Lesson learned. Summary - Too much of a good thing is not a good thing. But just the right amount is great. Note: Don't use this product when entering the flowering cycle. Waxy cannabis flowers aren't very useful.
