**Q: which product in the GH flora series do you add first . both armor si and flora micro claim they need to be added  first**
A: Always add your silicate first allowing it to dissipate completely in the water prior to adding anything else. 5mins or so...The silica will bind to everything around it locking everything out so don’t give it anything to bind to..

**Q: Can silica be used in early flower at heavier doses to reduce plant stretch and node spacing?**
A: Hello,

Silica can be used in early flower.  It helps with stem and stock thickness as well as heat and drought resistance.  Keep in mind silica supplements are alkaline and will raise your ph.  

Thanks,

Eco

**Q: Does it kill microbes?**
A: No
