I dont really think it would increase it by 2 weeks or so, what i meant, is it seems the same strain which i've been growing for about 2 years now takes about 10 days longer to show its first pistils, But i've noticed the growth is much more aggresive, but i've added 2 new additives to my nute regime, Compost tea and Sea Acids, but the apollo 6 has 90 degree leds and is focused on the middle part of the tent, and the 2 blackstars are on either sides, and im sure the new additives have increased lushness and growth rate. A ex mother plant is under the 500bs and growth is different on teh colas which are on the far side of the tent which are not receiving any white light, while the buds which are receiving white light look completely different, I really need to post some pics of this, hopefully i shall get sometime this weekend.
Happy growing and peace to all.
