Yepp! I would bet the same. Could be genetic but I feel it somehow..
I really like to take my clones when I switch seed based plants to flowering mode. There are always a few small shoots to lollipop in the lower area and these are perfect siuted to root them. The lowest twigs always root the fastest cause they have almost no auxin stored.
This way you don't need mother plants but you are forced to grow the same strains until you start with new strains. You could veg and meanline them parallel to the plants in the flowering tent and as soon as these are ready you can put the clones in the flowering tent, switch to 12/12 and take a bunch of new clones.
The flowering tent would run all the time in the best case but you need a 2nd tent to veg the new clones at the same time.
Especially when you've found a strain worth it it makes sense. The older the genetic gets the better the quality.
Is there no dispensery where you can buy rooted clones?
You could also order them and they'll send them as express package.
But don't ask for a specific strain, ask them for their oldest and most potent genetic. You have seen
@Moflow 's sensi star... It's really worth it!
If I could buy them legally here I would always take clones. It saves you a lot of time especially with 3 flowering tents!
Strains like GSC, GG#4 or bruce banner should get really awesome with the time and most cutting sellers keep their motherplants for a long time. Simply try it out with one of your next grows.
Also the method above saves you a lot of time cause you would always have a filled flowering tent and the cuttings can grow big in parallel.
