SBCannabisCo
started grow question 5y ago
Starting week 4 Flower, I have my light (Viparspectra Par600t) 70% blue 90% red they recommend 100/100 for flowering. What u guys think? I kinda don’t wanna blast it with blue because Viparspectra are already high on the blue spectrum.

I need help choosing a better light for my single plant microgrow!
H50cm W37.5cm L57cm Now using 1 household 13w Phillips LED 2700K for flower, a 120w CFL for veg and I use a cheap 20w dual Spectrum LED that I'm sure does almost nothing. See pics for convo with led sales guy. Is the height really that much of an issue with the light intensity?

Information on led grow light.
I am growing one plant of OG KUSH AUTO strain from Nirvana with light setup of 200watt of white led flood light and 300watt of led grow light. Is this much light enough for a single plant? I am using soil as grow medium.

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?
