    Second light with TS 1000 (80cm x 80cm x 180cm)

    Hey guys, so for some reason I thought it'd be a good idea to slap a 3rd plant under a TS1000, all are popping up nicely and all, but I'm thinking I may end up needing more light. Like double more. Or at least TS 600 more. I know a second TS 1000 would be just easy to go with, but what about...

    Hey guys, first time grower using a 135w v2 rspec quantum board Do you all have any suggestions for hanging height and power settings for this light from seed to harvest? I want to get the settings right by affecting the hanging height more than the dimming if possible but I’m open to...

    More light or more plants???

    What's up AFN. I recently purchased a larger tent and will be running more light for my next grow. I have a 5x5 tent and 4 3500k cobs from Cobshop.net. I have seen most people recommend running one light per plant, but I am wondering if it would be better to run 2 cobs per plant? My question...

    Grow light recommendations

    Looking for light ideas for a 4 by 4 tent that won't break the bank. I have looked at so many lights and reviews I have drove myself crazy. I will be running a 6inch 440cfm fan, heat output of lights wont be an issue. I have looked into cob lights but being my first grow trying not to go...

    Running seeds 12/12 no veg

    Hi all! Bit of a dilemma.. I am curious if anyone has ever done a whole auto grow under 12/12 from day one? Wondering if it would be ok to just throw an auto or two in the flowering room to veg while some reg strains were finishing off. Then when the reg ones come out the autos will be mid...

    Green Light Drives Leaf Photosynthesis More Efficiently than Red Light in Strong White Light:

    I've known for a while the the idea that green light was not used by plants to be false. However, little did I or most other expect to see these results. Information is from: Department of Biological Sciences, Graduate School of Science, The University of Tokyo...

    T5 lighting

    Evening all. I've been giving thought into turning a disused cupboard into a propergation/seedling room so I can obviously prep future grows before they go in the big tent. I have been pricing it up and I've found a good deal on T5 lights. The question I have is; are these lights any good and...

    Cfl vs led

    Hi, all! Good morning from 55 degrees North. Brother @2Stoned2Care recommends led. I listen to people who knows more than me. I am a student still. Led is expensive and I have large 250W cfl bulbs. I would be very thankful if you guys would disuss the two light sources. I consider another...

    The Adventures of Frankie's Auto Cab!

    Hey guys, I figured out it'll be easier just to have a single thread for the different strains I am growing at the same time. Some would call what I do a 'perpetual grow' I suppose but well, nothing's eternal ;) Only autos. Here is a summary of the current state of the 3 Fastbuds I am growing...
