Is this ready for 12/12 yet ?

[gunge9]

My understanding is that one should wait for pre-flowers prior to jumping to 12/12. I guess it all depends on the strain where some might not show unless their nights are longer.

In terms of growth, my current grow has easily doubled in size since switching to 12/12.

Nice tight plant.

Thanks for the advice, i think i`ll give it another week.
