Chop em and never buy feminized whenever possible. Straight up regular ol weed seeds.
TGA Genetics always come through for me and usually get more females then males, Ethos is also a good company.
No need to mist. Personally I run clonex @ 5ml/gal and hormex @ 2.5ml/gal with 99% success. Recently I added a heat pad and cut a few days off rooting time.
Hope this helps, good luck!
Those temps are not ideal but I have seen worse. Beneficials will def help in any situation but as far as my DWC goes Iv been using root life microbes from key to life and my roots and plants have never looked better. Id suggest checking them out.
I have read higher PPM will get you better quality but less yield and vice versa but lowering PPM in my garden didnt effect quality and had big impact on yield. So I wouldnt suggest trying to hit 1200PPM but you need to play around and figure out what works best for you and your garden.
I personally max out @ 900-1000 ppm and yields have been getting much better with these lower numbers (almost hitting 2 a light) so I would suggest leaving it.
Im running almost the same set up just DWC for bloom instead of ebb & flow. I have tried both hydroton and rockwool cubes when transplanting into flower and both work great. I would just suggest taking wrap off blocks and making sure all rockwool is covered (hydroton makes this easy) to prevent...
