Hey fellow farmers! So ive been doing some research on 12/12 from from seed schedule and seen many links pertaining to it.
I understand that on a 18/6 schedule you switch to 12/12 to begin flowering.

How would you begin flowing if you started on 12/12 schedule??

Im still going to continue doing my homework but any extra information would be much appreciated! :)
 
ya you're flowering from seed. takes a bit longer for the plant to sexually mature. but a good option if you're limited on space.
 
Well I am currently using a mh bulb... when I see it start to to sprout hairs should I switch to hps? If so how soon after do I switch once I see hairs? Thanks you guys!!
 
It has to grow to a certain point before it will begin to flower regardless of lights. I personally would recommend a 3-7 day veg to help kick-start the grow process. It isn't going to start flowering for another 2-4 weeks anyway. For an example....

That is 3 day veg then switch to 12/12.
 
Ive started 12/12 from beginning tho..they are bout 32 days old now. No sign of flowering. But when they do flower do I leave my mh bulb in? Or switch to hps
 
To minimize stretch,after you see pistils,keep your mh bulb on till stretch phase is over then switch to your hps to finish flowering.
 
Your welcome:)..not and end all be all perfect answer...every situation is different,but it's what would be recommended.GL.peace
