light

I was recently gifted some seeds by a wonderful forum member, and among them are some auto-flowering strains. I would like to grow one. However, I will be switching to a flowering light schedule (for phototropic strains) well before one could possibly finish; possibly within a month. Has anyone...

someone said One reason why CFLs sometimes look bad is because unlike incandescent lamps CFLs can't produce all of the colors in the light spectrum evenly. If you look at sunlight or an ordinary light bulb through a prism, you will get a perfect rainbow. If you look at a florescent lamp though...

Going to space and growing weed have one major element in common. No, it's not how high you get. It's LED lights. Neil Yorio, formerly a researcher at NASA, has taken his expertise preparing for space flight and applied it the craft of growing cannabis and other plants. Yorio. who used to...

Hello, new to the forum and growing. Last year i got a small 32 inch by 32 in tent and a mars hydro 300 light. Been getting some decent results. Recently she increased my allowance so now I have a couple of hundred extra to buy a new light. Would the mars 2 400, or the mars reflector 96 be...

I needs some advice...I thought I was growing THC Bomb Auto but obviously it is feminized. I have been using 20/4 light schedule and just 2 days ago removed THC to another room for 12/12 to start the flowering...so my question is do I stay 12/12 until harvest or do I change to more light hours...

So I came home from work to find my small 6" fan sitting on top of the net pot. Unfortunate. This seed sprouted yesterday and it is my very first grow of anything, ever. This is an autoflower. Does it look like it's going to bounce back? This picture is about 10 minutes old as of this writing...

Hello, I'm a new time grower here, I was lucky and cracked two seeds out of a very, very, very old storage (found them in my uncle's old trunk) any ways I planted em, and set them up with a 125w light and let them under a 24 hr light for 2 1/2 months. Now I have upgraded to a 400w high...

After all my research I've come to some conclusions but I'm still feeling a bit unsure, I'd really love to get some expect advice from you guys. My setup is 4x4ft - My budget $400. Here we go.. LED + Low Power, Red + Blue light good for end-bud development - Poor canopy penetration, mixed...

Hi All! I've decided to start a new journal since my last one was getting a little long and picture heavy. Besides, this one is over halfway done and I know how much everyone likes to see plants develop in less than a page. The link to my other journal should be in my signature, I will check...

We use quite a bit of the foam boards/sheets that are normally used for insulation in construction. They are 4' x 8' and available in several thickness. We use the 1/2" thick to screw/glue to walls and the 1" thick as movable 4' x 8' panels. They insulate, reflect, are impervious to light and...

can some1 explain to me the benefits, if any, and the cons of running all red, all blue, or having a light that has both during different stages. is it worth having one red light for flower and one blue for veg vs just having the same wattage light that has veg/flowering switches that are both...

Do you guys trim the smaller interior branches that don't get much light during flowering? There's some tiny buds trying to form on those. But I question if trimming them will let the plant put more energy into the good areas of light.
