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.

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

Hps mixed with mars hydro 600 yield?
Hey all! So i been thinking about ways to cut heat of course lol. So I’m thinking about getting a mars hydro 600 and running it with my 400w hps at 250w on the dimmer. Do you guys think I will yield about the same as if I was just running the hps on super lumens?

Light doesnt cover every pot
So i've got 2 plants under one cfl lamp and i observed that that 1 girl is reclining to the right. As i see my Cfl this girl is standing right below the plastic part of the cfl and obviously gets less sun. How can i fix this? Changing place my pots every day will do the job?

Led on 18/6 grow/flower photoperiod
I have the idea to put a led in my second tent for pre growing photoperiod girls, I have some room left over for some autoflowers who also grow & flower on 18/6 light - leds can switch between grow/flower. If I switch the led to flower will that be OK for my photoperiod girls?

Lumatek attis 300W
Good afternoon Farmers. I have a Lumatek Attis 300w LED and I'm using it at 100% (it includes a dimmer that can be adjusted in 20% increments). I wanted to know if there’s any problem using it at 100% from the initial phase or if there are specific values for each phase. Thank you very much!

Should I keep my light hours or take it back down?
I had 20/4 lightcycle on my autos but because of humidity problems, I had to raise the hours with light on. First to 22/2 and now I had to put it to 23/1. Tomorrow I will get another LED lamp and soon a dehumidifier. Can I then turn it down to 20/4 again without too much stress?

Light power
Is a 100-watt lamp sufficient? I don't consume much, so I opted for a modest light, anticipating lower yields. Can the quality match that of weed grown under a stronger light(600watt), despite producing fewer grams overall?
