I had excellent results with my first and only auto,dinafem auto amnesia...
I've grown thousands of photos,but was very impressed still by this strain...37.5 grams, 2gal smart pot,dynagro foliage pro,soak in nute bath..(I used the runoff/old res nutes from my hydro to feed)..I reccommend it as it was simple,and yielded good,with good buds..lots of compliments!
So to answer your question,I'd have to go with dinafem from my experience with this auto and photos ive grown from them,all being top notch,im sure the blue kush would be no exception...good luck!
My experience with Dinafem autos is top notch. I mean, I drop a bean in some water over night then put it in a 1" cube in a Dixie cup filled with perlite, set it on the windowsill and wait for it to pop. Keep the cube moist and have a 100% success so far with Dinafem.
They are so easy and hardy it's pathetic. Transplant to final pot after say a week maybe 2, I like the 5 gallon hempy bucket with perlite and vermiculite best because that makes it even easier. I do usually start feeding it after about 2 weeks at about 25 to 50% of what the feeding schedule calls for. Depends on how the plant looks. Then work it up to what the plant can handle. Keep your PH right and only rarely do the PPM meter since, I have been using the same nutes for a while, either GH flora 3 part or Recipe for Success nutes. They both work fine. I do flush about twice the grow and usually feed water or maybe feed water water. Always adjusted to about 5.8-6. I also like them to be pretty dry between water/feeding.
Give em some fan air and the good light they need, maybe 100 actual watts of LED and have had success with CFLs as well. I've done both the 12/12 and 20/4 and to be honest, they both work. 20/4 probably does bump up your yield a bit, I don't really know because I am always trying different stuff so have no data to compare.
I honestly have never had any problems with Dinafem genetics. Guess that's why I keep using their stuff. I am sure there are other quality genetics as well, I'm just kinda like F it. This shit works so keep doin it ya know. I did grow out a really aggressive RoadRunner once and had to trim that plant 3 times it was like a total bush. It gave a really good yield even tho I used MG soil, nutes and CFL lol. My best auto grow actually. Other than that I rarely trim and just leave it alone accept for feeding.
That's it man. Never had any problems that I can think of. Easy peasy. Don't BF it to death ya know.
