Sure, I'd use it too if I already had it. I wasn't suggesting that you not use it. I was researching it and then trying to figure out an alternative that didn't have the huge markups of the hydro shop products. Similar to what Atomizer is doing with the Canna Flores.I hear you there... I think for simplicity, I'll test the Pro-tekt, and also without. If I notice any benefit or negatives being either attributed to the silica or extra P I will post. I don't know how many decades a pound of dried Si02 would last me... hehehe Plus, wouldn't want my flowers to smell like sausages- hahahhaa. ( I know, it's probably used as a preservative similar to sulphur dioxide or nitrates).
EDIT: I clicked the link, guess it's an anti caking compound. Do we know if once it's bonded to the oxygen that it's still available to the plants? Perhaps there's a reason they use other elements to mix with it for plant uses... It's still not pure silicon, yet I agree oxygen sounds like less of a worry in terms of skewing the nute ratios. But I'm not exactly a chemist.
I chose SiO2 because it is the same silicon source used in Pro-tekt (Botinacare silica blast is derived from Sodium Silicate and Potassium Silicate). If you look on the label Pro-tekt is 7.8% SiO2 and 3.7% K2O.
I know a pound is a lot, but the shipping could end up being more than the product for smaller quantities, now that I know it is used as a spice I'll keep an eye out at the grocery stores.
Wow that's a lot of water for a single plant. Finally a plus for smaller chambers ... even though I'm working on a design for a larger one (~25 Gal)Today the test subject looks pretty wilted in the leaves. There is some new leaf growth, but the old leaves look like they might all die off. I haven't noticed any new root growth. There are a few variables, heat being my biggest worry. I think the roots are pretty wet with the new cycle, matter of fact I burned through 5 gallons of nute water in 15 hours for a single plant. The stems seem firm, so perhaps I should have dialed the mist down. I think I probably hurt the roots too much by taking them from soil, but as mentioned, the pod reaches about 98 degrees each day, and that sounds like the biggest issue.
98 degrees, sounds like you need something to reflect back the sunlight. I wonder if it would cool down once it's under the canopy.
