I have perfected outdoor washington growing...greenhouse and some creative nature tricking are best...1. make the floor of your green house your "pot". create the best soil possible. 2 start early as you can..as soon as there is 12 + hrs of daylight. 3. use inner black plastic lining to reduce light to under 12 hours daily when your ready. IE, roll it up at 8 am and down at 8 pm...do this early enough so that plants finish with before mold is a problem. 4. Grow early finishing strains, I suggest Grapefruit! 45 days finished.
