SilicaMax is usually only used once in the spring and then again once before harvest of any crop. Due to SilicaMax being relatively severe in its action, it should only be used after Etherics 1000 or prep 500. SilicaMax can be applied the next morning after either of these products, or even a couple of weeks after them if it suits your program better. From our experience SilicaMax has the same effect as the traditionally stirred product, however SilicaMax needs no further stirring. It is therefore very easy to obtain, store and use. (46)
SilicaMax ... is understood to bring a strong upright structure to a plant, by strengthening the cell wall. This has a wide range of benefits from increase plant health to an increase in plant nutritive quality. Interestingly trials carried out by various people, including some of our trials with HortResearch, have been unable to show any increase in photosynthesis through using 501. However simple observation shows it inclines plants to stronger flowering and better taste. This tendency to increase flowering is one of the reasons that we developed PhotoMax. We noticed that 501 can only be used sparingly throughout the season or it will impact strongly on the plants growth habit. So we looked into the other BD preparations to see how we could strengthen the 'silica process' and photosynthesis without altering the plants growth habit. Over the years we have found PhotoMax achieves both these goals. It can be sprayed every few weeks throughout the whole season, especially in times of low light, without unduly effecting the basic growth habit. Trials have shown increases in dry matter, increases in brix and - more recently - reduction in leaf nitrates, without plants tending to seeding. These two products perform different activities in the plant. SilicaMax provides the structure plants need, while PhotoMax works more on the internal chemistry of the plant through enhanced photosynthesis and all that this brings. We use both in our programs, however SilicaMax is usually only used once in the spring and then again once before harvest of any crop. We use PhotoMax mostly in regard to the available light. If there is a dull period then use PhotoMax regardless of the time of year. Early spring is naturally one of its prime periods as it helps plants get a very good start to the season.
