A great product, as usual
Size: 1 quart
I recently started using Botanicare Silica Blast for my indoor and outdoor plants, and I’m thrilled with the results. The product arrived on time and in excellent condition, with no spills or leaks thanks to the impeccable packaging and shipping. Right from the start, I noticed the quality of this supplement. The liquid is easy to measure and mix into my regular feeding schedule. I’ve been using it for a few weeks now, and I can already see a noticeable difference in the strength and vitality of my plants. One of the standout features of Silica Blast is how it helps reinforce plant cell walls. My plants, especially the ones that are more prone to stress, have shown significant improvement in their overall health. The stems are sturdier, and the leaves look more robust and vibrant. This is particularly important for my heavier flowering plants, which need that extra support to handle the weight. I also appreciate that this supplement is versatile and can be used for both soil and hydroponic applications. I have a mix of both, and it’s convenient to use the same product across different growing mediums. It integrates seamlessly with my existing nutrient regimen without causing any imbalances. Since starting with Silica Blast, my plants seem more resistant to environmental stressors. They’ve handled temperature fluctuations and minor pest issues better than before. This added resilience has made a noticeable difference, particularly in my greenhouse where conditions can vary more dramatically. Overall, Botanicare Silica Blast has become an essential part of my plant care routine. It’s easy to use, highly effective, and delivers noticeable results. If you’re looking to boost the health and strength of your plants, I highly recommend giving this product a try. It’s definitely made a positive impact on my garden, and I’m excited to see continued improvements as I keep using it.

Great product at a reasonable price
Size: 1 quart
I've used this product in an indoor hydroponic grow system. It tends to raise ph levels, but I do believe that it makes my plants more resilient. If you need to keep ph low, have some acid handy to bring ph levels back down where you need them after using the silica blast.

Really noticeable difference in plant strength
Size: 1 quart
I picked this silica supplement to add into my regular feeding routine, and it ended up making a bigger difference than I expected. The effectiveness is definitely there. After using it consistently, I started noticing stronger stems and overall healthier-looking plants. They just seem more solid and less fragile compared to before. The plant attraction/appearance improves too. Leaves look a bit more vibrant, and everything just has that healthier, fuller look. It’s not an overnight change, but over time it’s noticeable. The pest control benefit is a nice bonus. I didn’t completely eliminate pests or anything like that, but my plants seem to handle minor issues better and don’t get as stressed. The ease of use is simple enough. You just mix a small amount into your normal watering or nutrient routine, and it blends in without any hassle. Once you get the ratio down, it becomes second nature. The concentration is strong, so a little goes a long way. I’ve been using the same bottle for a while now, and it doesn’t feel like it’s running out quickly. The bottle design is solid, and I didn’t have any issues with leakage. It seals well, which is important since it’s something you don’t want spilling. It also works well across different setups, whether you’re growing in soil or something more controlled. The only downside is the price is a bit higher than basic supplements, but considering how long it lasts, it balances out. For the price, the value for money is still pretty good, especially if you’re focused on improving plant strength and resilience. Overall, this is a really solid addition to a plant care routine if you want stronger, healthier growth over time.

FOR STRONGER STEMS AND BIGGER BLOOMS
Size: 1 quart
I don’t know how well it works, I add it to water for plants. Just a little goes into your water. Kind of pricy, bottle lasts a fairly long time. I’m amateur, just read plants need it for better stem growth and flower bloom.

Secret ingredient to keep PH where you need it
Size: 1 quart
After using this product on my cannabis plants for the pass year, I came to realize that this product raises the PH of my RO water from 6 to 9 using the recommended dosage per gallon. At first this was really annoying after adding some nutrients from Botainicare GROW and CAL MAG(recommend dose) it would lower the ph to like 4.5. Way too low for my needs. I would then have to add ph-up to raise to 6 in veg and 5.5 in flower. This would start the ph swings in my reservoir high and low and start seeing issues in my plants because I got tired of having to readjust ph every day. I use the autopot system 3.9 gallon and use a 7 gallon reservoir. Image show at week 8 flower. Yellow leaves ph out of control, green leaf picture week 8 and still green ph under control. With that being said now I use the Silica as a ph up and the Botanicare GROW, Tea compost, and Hydroplex as ph down until my ph is where I want it to be at 6 in veg and 5.5 in flower. FYI now my ph does not move one decimal. I would recommend using Biotanicare nutrient line with this others may work but I have not tried them.
