Biscotti

Experimenting with light duration: Set lights to 13h and stretch started as planned so why not always use this extra hour for more photosynthesis? Probably also depends on strains, some may not start flowering as easy as these 4 here Also added 1ml of extra PK at the beginning of the week as i heard Prof.Bugbee talking about an abundance of P while initiating flower being very supportive...didn't hurt so far... Can't wait for more stretch and more flowers next week!
