just put her under a floro bulb and fertilize, then wait till you see new growth after about 2-4 weeks depending on strain vigor. OG varieties has strong vigor in general so you should be seeing pods turn into leaves in 2 weeks. When you see the first sign of new growth, trim off the buds that are showing less signs of growth(you can dry and smoke these just like harvesting..it even tastes better and gets you a great body high). This will focus the plants energy on producing 1-5 main stalks(you can manipulate how every many tops you want at this point by the number of buds cut off) as opposed to 25-50 tops if you just let her grow like she is cut now. Each pod on your buds have the ability to become a main stem, with this in mind only 1 bud is necessary for regeneration(although some strains will not tolerate this so make sure you have clones) each bud containing numerous pods. When regenerating you have the likely hood of having a lop sided plant come flower time that could potentially fall over, to avoid this you have to train her as she grows. I love regenerating and its a great way to preserve the genetic health of a strain(numerous cloning of the same plant weakens the strain genetically)
