ok ok original OP here... my title says 'silicon' but what I meant was 'silica'. Sorry
Does that change opinions or was everyone assuming thats what I meant?
Here's a cut n paste from another forum....
------------------------------------------
Silica
Silica is not silicon, it is an element that cannot be put into the nutrient formula, due to instability, but it should be part of any plants nutrition.
Consider silica like a missing link between plant vitality, strength, resistance to infection, and increased harvests.
The silica helps strengthen cells, and plants are much healthier from the continual addition of silica.
Ensure you have a highly soluble form and you will begin to see effect from around 2 weeks onwards. Budlink, Silica magic or Dutch Master silica are very good forms of silica.

Anyway I don't understand the technical side of the chemistry, just want to hear/see some real world results.
And fuck yeah, I want to see pics of everyones plants and if yours look shit hot I'll be a lot more inclined to listen to your comments.
Put up or shut up
