Yup...You have to start the whole cycle from scratch in normal order to ensure a good grow, and cloning has to wait until plant is around a month old, in order to have healthy clones. You cannot rush any part of the early development of a perpetual grow. Because that's what your shooting for; Right?

Wait until plants are old enough to clone. then take 2 or 4 clones from each one. Mark them so you know which is which, About the time that they are rooted and ready to veg...flower your plants! they should be 4-5 weeks old and, once they show their sex...Kill the male plants and clones...wellllaa...Now you have some plants flowering...and some clones vegging...
Use a couple cfl's to veg your clones and you won't need a lot of space...
You can continue this process. minus the sexing part, and take a couple clones from each plant or Start vegging one of your strongest growing clones and perpetually veg it as a MUM...In which case you can take a couple clones whenever.
