i have noticed some strains like to "clone"/propagate cuttings MUCH better than others, tend to be the ones i would keep around, like a grow-tent natural selection-
the sr-71 i would and am still running it after years using a method where i will take clones from a mom for a few generations or so, run her, take more - pic the BEST mothers and did that for years and found for a long time if i kept the RH and temps in check and clipped off bad leaves ect and kept the clippings healthy they in turn would increase in vigor through a 5-6 plant selection even over many many runs -
have gone back to more propagation based recently, if i ever (once noticed loss of vigor and or needed to clean out all the equipment and area ect , back up into a BX from one hitting another)- the seed seems to have as much or MORE vigor than the starting plant even, not to mention a lot of resilience to temp swings huge nute changes ect it is just a bruiser in that aspect,
also idk if this is more the environmental control system the resiliance factor or just LUCK , but getting near 100 percent propogation rates , mothering and vegging under one CMH-315w , and notice no diseased leaf ect like under the plublurples, it seems to do well all stages of seed/cuttings veg and keeping a mother (or 2) going as well, can keep Rh in humidty dome in the tent good for propagation and then ride a 55-65% rh and i bet its the small uv-b that comes out (380nm) but it keeps cuttings healthier and root much better than at least "Shitty led" - just a note as any cheap system is like 100-130usd and can do eh 2x4 or even up to 4x4 with better reflectors would wager, have been having good results- note i use an adjustable dual side reflector hood - keeping it open temps are managable - close it at your own risk - have never tried "standard" hoods but looking at how close they hug the bulb or BULBS too much heat - i find opening it and keeping it as high as possible without touching the celling and close to the extractor it keeps it always warmer than ambient but not more than 5-7f in a small tent even-
just for an "all in one" type solution for any plant not on 12/12 a universal nursery/veg room- saves a lot of time/space/-boosts efficiency imo lol checking all the plants in one sweep vs 2 or more tents for that- not saying thats bad if you have the $ and room go for it i would lol but if your on very limited sq ft and power- eh this setup has been doing pretty well for a diy type thing-
a good setup for seed/cutting to at least veg - and or holding plants and then more cuttings if needed having that option in a small package is a godsend for me at least- frees up line and space for the big girls flowerin thats always good imo lol
