Two curious questions!

1) Why is the recommended pH for soil different than soil-less? Wouldn't the roots be rather oblivious to what the roots are in and only care about what it needs? So why does Nitrogen, for instance, get locked out in hydroponics at a pH that is ideal for N uptake in soil and vice versa?

2) Would a plant that is still in vegetative go into flowering if you ran a rather odd schedule of 12/4/4/4? As in 12 on, 4 off, 4 on, 4 off - repeat. Not that I want to try it, but the point is, how much dark does it take to trigger flowering? I'd wager that it would either cause the plant to reveg or herm badly if it were in flowering, but what if it had never flowered and was subjected to that schedule?

Curiosities I had been running through my head lately. Maybe someone here can answer!

its gets locked up in hydro cuz the availibilty of other nutes is too great and will overpower nit. in the veg stage. but in the flower stage i have seen higher ph used. but really soil oh and hydro ph are not that big of a difference and depending on you nute solution you could run a soil ph but most nutes come packaged w/ npk bundled together so to make sure the general pop. does not end up with nute locked plants they tell you the general ph is lower in hydro. the reason for this is i dont have the chart im sure you could google it is that nutes are more available at a certain ph but also root uptake of nutes also depends on the not the size of the roots but the exposure (area of root that actually touches solution) if intake is too high you will poison the plants thus lower ph with mixed chemicals in hydro


a plant needs 12 hours darkness to flower it has to do with a build up of hormones. say if you were to do 12 hours dark 4 light 4 dark 4 light then back to 12 dark. the plant would probably flower faster but yield less becuz it is losing 4 hours it could have been photosynthesizing a day. if you did it the opposite 12 light hours youd probably either not flower or get hermies

alos a lower ph i hydro keeps down on alge build up in water.
