what is your reasoning behind such a short veg? my opinion is that there is a reason that plants veg for a certain amount of time and then flower . the reason is that they have to grow enough to be able to obtain and store the energy they need to flower. because of this you should not try to shorten the veg time or the yield will be affected. another reason is that sexual maturity is in the dna. 8 year olds cant have babies for a reason and its the same with plants. anyways i could be totally wrong but i thought id put in my 2 cents.
