Im wondering if it would be benefitial to presoak my seed starter rockwool cubes in 20% strength nutes or maybe just a root stimulator like subculture or something. Or should I just go with distilled water set to a pH of 5.0 to compensate for the alkalinity of the rw cubes and soak them for 24 hours once the ph stabalizes at 5.8? Which method do you guys find works best?
btw, as I said before they are for starting recently germinated seeds. Also, Im not sure if it matters but they will be autoflowering strains
 
I presoak my cubes (for like 20 min.) in R/O water ph'ed to 5.5 and that's it. I have had great success with this simple technique including with auto-flowers, really the only thing I grow from seed anymore.
 
I can be beneficial, but unnecessary if you have healthy, vigorous plants.

I've used Shultzes rooting powder-- you know, the cheap stuff-- and ph adjusted water, + plant and rockwool plug for 8 years. 99% grow legs within 10 days.

thats awesome, thanks man. good to hear a tried and true technique on starting autos
 
i soak with with bioroot something like 4mg per gallon just a little to help out the roots , because even before you can see them they start to uptake nutrients so they will defiantly be eating up that stuff.
