AgroMagen, Si-Tech Silica, Mono-Silicic Acid Plant Nutrient Solution with Chelation Technology (4 fl.oz)

This is a definite game changer for my variegated plants! They are so much healthier once I started using this product monthly, just adding it to a watering. They have stronger stems, stronger and larger leaves, and less issues with browning where the lighter parts of the plants grow. I definitely recommend this to anyone who grows houseplants and loves variegated plants especially. Along with a water conditioner, this has completely removed all brown tips and edges to all the leaves on my pothos N Joy, my Silver Streak, and syngonium Batik. My hoya Krimson Queen has juicier leaves as well. I also add it to my non-variegated plants watering schedule as it helps them develop healthier foliage as well. All my houseplants look great, I'm so impressed!

I purchased this item a few months ago and have had a chance to use it. I am currently using this product on four plants in my grow tent. I have now used this 3 times in 9 days at the recommended strength. Unbelievable, My limbs have doubled in size and will now be able to hold up some large buds. My plants actually look healthier. I'm stunned. I use to use the #1 rated potassium silicate. This is my go to silica additive from now on. The difference between potassium silicate and mono silicic acid (MSA), is night and day. This product is very easy to use. I simply put my nutes in regular order, then add MSA and then PH my solution and feed plants. This usage is from their customer service. Don't think even twice. Just buy the smallest bottle to evaluate for yourself. Happy growing!

Not sure of the direct effect just yet from this but overall my variegated planties seem to be enjoying it. I don’t get as much browning and this is so easy to use.

Inexpensive msa. Has done well in 2 grows used.

Although I have used other silica products and they work well, I can see a difference between them and this Si-Tech brand. This stuff is amazing. I’m no scientist for sure, but it seems to make the branches and stalk stronger but also flexible. Others have made them strong but stiff as a board. I can literally pull a branch down a ways and see it spring right back to its original position. I will be using this brand from now on ( though I won’t have to buy it often as a little bottle goes a looong way).My plants and I highly recommend.

As I'm sure most of you know, your traditional Si additives use potassium silicate - which causes PH to spike. As it's absorbed it can also cause PH swings within your medium. Not only does this Agro product not have the PH issue (it's about as close to PH agnostic as you can get), it's also crazy simple to use. 5 drops per gallon of solution - easy easy easy! My fav Si additive!

I only write reviews for products that stand out, good or bad. This one is great! The most biologically available form of silicon for plants. Subjectively my plants stems and leaves seemed stronger after just the first use, (after a week) but I can’t say for sure. However, over a few weeks of use the plants became so strong that my little bit of fingernail pushing through a stem during pruning has difficulty getting all the way through, and now i have to use scissors. I bought the smallest container they make, to test this stuff, which is like 4oz I believe, but this brand will be my new go to, and I will be buying the larger size. Buy the little bottle to test, and you won’t be disappointed.
