you need the "lead in" period..(thats a great way to describe it! thanks!
(everyone will probably start using that now!
No, dormancy doesnt "happen" in July/August..but the "lead in" period begins in July and August..arguably the dormancy process begins at the Summer Solstice in late June..when days start to get shorter..the plants then begin the gradual "lead in" period through July-Aug-Sep-Oct..Maybe July isnt part of the 'lead in" period..its a grey area..but August and Sep definatly are..
Humans ooperate on a 24 hour cycle of awake-sleep..
Plants operate on a 12-month cycle of awake-sleep!
Plants need all 12 months..with different photoperiod and temps in each of those 12 months..
which, again, is why growing VFT's and Sarrs indoors is no good..you cant replicate the subtle differences month to month..but the plants need those subtle differences..because "lead in, dormancy, wake up, growing" are each long drawn-out periods, that blend into each other..
