Really it comes down to your available volume of clones. In a perfect world they’d be free and unlimited, but even if you make your own, they’re never free.
So, in an ideal world, a Sea of Green tends to yield the best for horizontal gardens. Vertical gardens usually yield more per light, or even rotary gardens like the Omega do very well. But Omegas and Coliseum grows both rely on large numbers of clones too, just the shape changes into a cylindrical SOG.
I’m of the firm opinion that veg time is overrated, indoors and out. We cultivate flowers, and their extracts, but the stems and branches are the only thing we spend time and money to grow that we actually throw away. 6 small plants can yield the same as one large one, but in a shorter timeframe. A shorter timeframe per crop equals more crops per year.
That said, I don’t have unlimited space for moms, cloning is relatively labor-intensive (and delicate work) but I run perpetual flower rooms, so i enjoy the comfort of outsourcing clones. I don’t have to worry about a batch being too small, or failing for some reason. Reliability and timing is critical, more than a couple days off throws off an entire crop, and not for the better.
Some of the “plants per light” you run is limited by your system, as most hydro systems (with the exception of trays) dictate how many plants can fit in a given space. NFT and aero use densely packed clones vegged just a few days. 2 gallon ebb and flow buckets need bigger plants, as you’re in ba 2 gallon container, vegged 2 or 3 weeks. Undercurrent systems come with you to 20 gallon containers, which are typically one or two a light, but can be packed with roots in 3 weeks.
Lots of ways to skin a cat, depends on how much you want to invest in gear and how cheaply you can make or get clones reliably.
