A great product, as usual
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.

This stuff is awesome,makes growing much less stressful
I add this to my watering once per week.It makes the stalk and stem of my plants extra strong and THICC. I no longer need support stakes when my plants go into flowering due to the extra rigidity of the stems and stalks. Also an unintended side effect of using silica is that it will help reduce the amount to fungus gnats in your soil due to silica being like glass shards to the gnats, which reduces ALOT of their population.I'd say by about 90%. There's always 2 or 3 but I haven't had HUGE outbreaks like I use to have in the past.Buy this stuff asap, best investment ever.

Secret ingredient to keep PH where you need it
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.
