just a tidbit of info to help you out in your genetics so you can get some great results... if you are lookin to cross two plants that are a result of say the seeds came from a different seed company or the seeds you bought had different genetics altogether and are crosses of a completely different phenotype and or genotype...
Then just be sure to cross your first two plants' seeds several times, otherwise you will have a very unstable genetic line and end up with alot of messed up plants with crappy yield and low potency (regardless of how many "seeds" the first or second cross produces)
be a little patient and wait the extra 6-8 months(theyre autoflowers they dont take that long to grow lol)
So cross at least a couple more times and it will be soooo worth it then you can keep plantin them till you have a large seedstock of your best cross and then keep that cross for future breeding between them and bam! youve got a kick ass strain
