I just want to let other gardeners know my experience with silica blast.It does just what it says,makes droopy plant tops stand straight up and makes the branches stronger too,revitalized my plants after a feeding accident burned the leaf tips and made them weak,after serious flushing (outdoor soil),I dried them out 5 days and then gave them a little of this at 1/2 strength in well h2o and the tops are back on track & they are straighter and stronger than they were before the accident,i aparently should have been using this suppliment all along,my plants always grew into short,beautiful bushy plants and while i liked them,i didn't know how to get them to grow a little taller (not too tall),i prefer knowing what each nutrient does,being able to feed my plants what they need exactly when they want it,is my idea of good gardening and a little goes a long way too,cant beat that.Thanks

I have been a fan of botanicare since the beginning of my journey. so 5ish years!! price was right and consistent. Well i got this deal a qt of silica blast for 7.49 its not necessary but its nice to add if its in budget. Well the flormula changed they took out the better form of silica the silicon dioxide and now is sodium silicate and potassium silicate. And analysis is 0-0-0.5. This is disappointing cuz silica products are getting really good 100% uptake with monosilicic acid. But you pay out ass for these but the work. Instead they went with less effective and not needed again. Ngood deal but not as cheap as food grade fresh water Diatom Earth mixed with my coco

I purchased this about a month ago for some lovage that I am growing hydroponically. After reading the instructions and reading some previous reviews I used this in my hydroponic system. I added the product in small amounts at a time because I didn't follow the order of addition listed on the bottle. However, I decreased the pH of the solution before adding each small amount of Silica Blast. As long as you keep the pH in check you should be fine. My plants are alive and well. Do I notice a difference in the plant behavior? No, not really... but I'm also not watching its behavior too closely either.

This stuff is amazing, saved my first hydroponics grow.

I had high heat and my plant grew like crazy, too crazy in fact and once bloom time started, the light didn’t phase the flowers even an 1” away from it. They did burn only when the flower touched the bulb. I have to credit this stuff. My previous dirt grow, plant was burning 8” from the light.

The heat didn’t even phase any of the plant cycles, 90F through the whole flowering phase, plant just drank extra water, no growth issues.

This stuff is a game changer. If you never used this I highly recommend it. I use it at 2.5 ml/gal early veg and 5ml/gal mid veg to end of week 2 in flower. The stalks on my plants are bulky and very hard to break. The petioles swelled up and when you defoliate you will feel a distinct pop when the leaf is pulled. This is great product to beef up you cell walls in your plant. For this price you won’t regret trying botanicare silica blast. Pics are late veg

I went with this instead of advanced nutrients rhino skin because of the price. Botanicare is good, but this time im not sure what is in the bottle.

The bottle had been opened prior to my receiving the package. I don't know if this was a return and of it was used and watered down. I even wondered if someone could have added something else to the bottle. Either way im unsure what I have and I can't risk damaging my plants.

Excellent addition to my supplements. Doesn't take much and you will notice shortly after application how your plant begins to strengthen. Almost impossible to bend stems a week after using this silica supplement. Highly recommended for all plants, outdoors and indoors. You will be pleased if you need strong healthy branches and stem for holding up heavy flowers or buds. No worries of breaking in the middle of your grow.

I am using Botanicare's hydroponics products on potted plants currently, before setting up my hydroponics systems. As soon as I started using the Silica Blast on my various potting soil based vegetables and herbs, their stems doubled in diameter, and they seem hale and hearty. I highly recommend using a silica supplement for potting soils, or in anything that does not have silica in the formulation.

I have used many different Silica products for my entire grows, it does benefit cell health, stem growth and disease resistance. This one I got because its NPK ratio didn't have the N my last brand did. I will go back to my previous brand's silica boost by bloom city.

i feel this product is absorbed at a lower rate as it's not attached to N when it's being absorbed.

Purchased about a week ago and I've noticed my trunk and main branches have become swollen yet still flexible and easy to train without snapping branches. I'm not sure what others are talking about when they mention it raising ph levels. I've had no such problems. 5 stars for quick delivery and ease of use + visual results in less than a week.
