No "outdoor" directions on my bottle. I only have the small sample bottles which i received in a reflector box. These are the only directions: 1. For ever 1 litre/quart of final spray solution add 60ml/4tbsp of liquid light together with 60ml/4tbsp of penetrator.
2. spray leaves twice per week until runoff.


Thats all...
i asked my hydro guy and he said he uses it outside, suggested only using it in the early morning so as not to fry the plants. Makes sense...and in my short career of cultivation, i have burned TOO many plants!!

I am going to go ahead and give it a shot manana
