If you set seeds going the same day has you take a clone,there is not much in it.take my word for that i have been doing test on this for several grows.
But i veg for 8 week with clones and seed strains along side plants in flower inc the rooting period of both.That inc min 3/4 toppings during that time.
When i say toppings i do not mean just the main top ,i top every single branch top,mainly to get more tops for when there ready to flower,but also to slow them down,because i am often waiting for the flowering plants to finish,so it a strain takes 9 weeks like the last one then i top again for the 5th time.Then has soon has they go into flower netting over them and train for 4 weeks of flower,no hard training though,scrog .Just tucking the tops under the netting.I grow seed plant and clones side by side,if you look at my journal.i just started then that set the middle plat the stardawg cross was,a seed started same time i took the sherbert clones
