They are supposed to grow out in nature where temp and humidity fluctuations are normal.
if I cared to keep it one number for best indoor growth 75-85 days 70 -75 nights. Humidity as low as possible without putting any money into it. Cover soil etc if necessary.
they are plants. they need good roots most of all, temp and humidity never needed any attention for me, lights on at night, off during day, keeps everything good enough or better.
Thanks for your comments. Unfortunately, many modern strains and cultivars have been bred and cross-bred to thrive in specific indoor situations. Some strains become very fussy, and don't do well outside narrow parameters. This is especially true for the "exotic" strains, which have sacrificed traits like ruggedness and tolerance in favor of potency or specific cannabinoid or terpene profiles. One of the cultivars I'm growing is a clone-only strain that does best in a hydroponic situation, and it is very, very picky. So, you don't always get great results by just planting them in the ground and letting the environment fluctuate.
Additionally, even in the "wild," different subspecies have different tolerances. For instance, what we refer to as "Indica" (modernly known as Broad Leaf Drug or BLD strains) evolved in conditions of high heat and low humidity, with a short vegetative and short flowering period. Take those plants to the tropics, and they will not fare well. Conversely, what we think of as "Sativa" (Narrow Leaf Drug or NLD strains) evolved near the equator, with long days, high humidity, and a long flowering period. Take those north of 30 degrees, and you may not even get them to flower outside, as that latitude lacks the length of season to allow the plants to properly flower. Some subspecies, like Ruderalis, grow so far north in cold climates and short seasons, that it would fail anywhere else, and both Indica and Sativa would fail at latitudes where Ruderalis thrives. All of the commercial strains we have today got their start in Northern California in the 1970s, as growers who mainly had access to Sativa from Mexico and Central America, that didn't do well in California, started breeding those strains with plants from Afghanistan and Pakistan that had lifecycles closer to the Mediterranean climate in Humboldt County, so they could grow them outdoors. Then in the 1980s, as indoor growing started to take off, even more mixing occurred, and often the ability to thrive outdoors was completely abandoned.
So, when we take all those subspecies and start altering them through modern breeding practices, and creating all manner of mixed preferences inherent in hybridization and breeding for specific traits, we can create quite a mess. Several very popular strains have almost completely lost their hardiness, and many hybrids can only be effectively grown indoors under specific conditions.
That's why I listed the three strains I'm growing, hoping that someone who has experience with those specific strains would be able to tell me under what conditions they thrive.
Of course, we can "ballpark" it, and we can go with general notions that work "well enough," and most of the time we'll get a harvest from that. And that's all fine and dandy. I was just looking for something perhaps more specific to these strains, if anyone knows them.
