I have taken 100-200 clones off a single mother plant. I also have cloned off of veg plants, that were clones from the original clone, and cloned them again and again, actually I did that for over a year. The problem with not having a mom, and just taking cuts off your veg plants before they get put into bloom is that if a round of your veg plants go bad....You loose that strain, also there is a debate on whether or not a strain looses vigor after a few times cloned....I think that may not be true due that fact there are strains out there that are just as strong as they used to be when they were first created, and are now only clone only plants, as in, there is no way to get a seed from them due to the genetic parents no longer in service.
Anyhow, I am rambling and just wanted to toss that in with all the clone talk....
Looking great D! they look like they are pretty dense, what do they feel like when you swat them "they love that"! Mine like it alittle ruff! LOL
