Silica additive

In soil grows its questionable if needed, in hydro I think its useful. Good Luck!

Wow thanks for the immediate feedback. I kept reading different opinions but didn't know they can gel with nutes. Definitely going to start at 1/5 dose around week 4/5 and build off of that to maybe 2/3. I'll see how it goes, thank you! Happy growing!

Think of it as a rigid plant tissue building block. More blocks = stronger/bigger plant, and these are blocks that the plant doesn't have to work for or process in any way. I have always seen it as arguably the BEST supplement for any plant - without drawback. But the plant doesn't "need" it, as it is not an essential nutrient - so there is some misconception and disbelief here unfortunately.

Well as for harvest. It doesn't really have an effect on harvest. What it does do though, is gives your plant more strength to be able to grow bigger harvests and support itself better, helps the plant as a whole to set you up to help get a bigger harvest, doesn't actually make a dif itself. Silca is great. I noticed difference when starting using during wk 5. Leaves didn't droop as much say if I overwatered and makes ur plant over all stronger Use it's great. Happy growing, good luck pal
