LED expert, 5 yr hydroponics vegetable experience but new to growing weed. White Widow auto first grow in custom 5gal pail-in-pail with periphery tie-downs to spread like a scrog, but can rotate freely. May diagram online- as this works well. Super hi intensity, 500umol/m2/S at canopy from transplant, 2 weeks later up to 1000umol/m2/S. 18/6 light:dark start to finish, 75F day 65F night, 6.2-6.6pH and 900ppm to bud then reduce N and nutes to 600ppm. I remember the REAL Woodstock.
