lucas formula outdoor soil

can the lucas formula be used in an outdoor grow using fix farm soil or something similar? thank you all

Why wouldn't it be usable? Stash some by your grow mix it in the water at site and go to town.

Yes, just make sure that if you use the Lucas formula on the forums here that you read through the whole thread as there are some recipe changes that are 'better' throughout it.. don't just read the first 2-3 pages.

thank you. where would I find that thread?
