hah. She got to about 8 litres/day (2 gallons) at her flowering. Some bud booster & calmag, nothing too exotic or much of tho. The soil was 30% wormcastings, 40% Sungrow Myco, and 30% vermiculite. She drained well, and took up nutes great. Total point and shoot grow. Followed Greenhouse seeds advice on outdoors - and let 'er dry up like a desert a couple of times in-between flushings. All organic, no heavy salts used.
I had one in the ground, but, it got to be about 7' tall, and when she started taking water to put out flowers - that one got really heavy. Lost a couple of branches in a windstorm, still have a 1/2lb dry I'm sure. I have no doubt it'd be a 3 pounder had she gone deep.
White Widow has proven to me mold resistant, super stinky, and enough trichs and development to think I've ended up with some spank dandy gear. I was going down to 5-6C at night, but they were hanging. I grew a couple of Afghanis last year, one turned into a petri dish almost overnight when it got cold and condensation came out. The other went 10 days deeper, and was grand, both in yield and smoke.
Will do a smoke report after this has had a month to cure out.
