I only vegged my clones for 7 days. Basically enough time to root into the rockwool cubes. They usually start their growth on the 6th day so I went into 12/12 on the 7th day.
I've never tried this before either, but my grow log is in my signature. Check it out. They've only been flowering for a 11 days and they look like they will produce some bud. I really don't know what to expect.
I did this because someone said that I could fuck his wife if I could get smokeable bud in 3 months, haha. I just want to see what I can do in less than 3 months start to finish.
