We all come from different walks in life, sure making clones aint free but IMO far from costly.
12/12 from seed can be a great way to test seed, I have done that on fairly large scale with 100's of seedlings.
And if we are doing pics, let me join in and share some from my old op.
Clones for the bud production, under a few 36 W fluro tubes. They are grown 12/12 from clone, they spend 3 weeks on the table, from they where cut from the mom.
Spend 2 weeks like this, then repotted getting ready for the flower room a week later.
The flower rooms, where 2x 15.000 watt HPS - Running that, compared to some flurotubes a few weeks. That is not a cost you really calculate into the budget, but you are right it's not a zero cost.
I'll show some of the growing
Sat dom plants 12/12 from seed
Later, but far from harvest
Canopy is crazy and out of controll!
Indica dom 12/12 from seed
Canopy is much better and even, but the time spend till harvest don't pan out compared to clones.
Yeald was fairly even.
Canopy looks like it's cut with a hedge trimmer, 10 weeks for a 10 week strain to harvest + 3 weeks rooting.
I am not selling anything, this is just my experiance.
Others will have other experiance I am sure, and that's not a problem for me.
Im sharing my experiance, in how you will make the most for less in less time.
If some can use it, use it, if not feel free not to
