Help Multi-Strain Scrog.

of course you can, just make sure they're all female and that you have adequate lighting to sustain the additional plants

Its likely you won't have issue simply from multiple strains. had the strains been vastly different such as Indica/Sativa, they may have given you problems in that the growth rates and "pre-flower strech" differ. Keep your an canopy an even surface through the first few weeks of flower during that stetch. Enjoy!

OG is notorious for a big stretch in flower sometimes so look out for that. You can Scrog whatever you want as long as you keep that canopy somewhat level.
