lights

I am using CFLs, T5's and LEDs. 18-6. Can I turn off all but LEDs for six hours during cycle and what negative effects would or could this have ? I am aware of losing wattage and intensity output. Any knowledge is appreciated. P.s. How in hell do you attach pics to posts ?

Hi everything was looking good kinda for my purple kush then i tried to add some more lights and the next day they looked like this. Any ideas..was it the lights? any suggestions? The top pic is the after pic and the bottom one is the before.....

Hello 420magazine, This will be my first time using a forum in regards to medicinal personal cultivation. I currently am on my first grow, 7 days from sprout. I have a complete 5x5 tent setup with ventilation, fan speed controller, and air cooled 600 Watt mh/hps, circulating fan...

Hey all, What seems to be up with my girl? The leaves are yellowing and wrinkly. Its a hydro grow and when i changed the solution today, the water level was kind a low, so I'm not sure if that could be it. Current specs of its environment and nute solution temp: 30C lights on 18C...

We've started our first indoor grow, built a grow box, started four plants off beautifully, and everything was going swimmingly (8th week of growing, and 3rd week of 12/12 schedule) but then I left the lights on for 24 hours by mistake. What should we do now (apart from panic)?

So I've been searching for information on the correct height your lights should be from your plants. Everything says about 18 inches away while flowering, however this is usually in line with a air cooled hps or mh bulb of a substantial size. I am using 2 400 watt 5 channel leds these run much...

Hello, I am new to this forum so I hope someone can help me out! :-) Is flowering 11.5 lights on - 12.5 lights off , ok for my plants? My timers a little off and I was wondering if this will affect anything? Iv heard people do 11 on 13 off also? Thanks Phil

How effective would it be to have 3 sets of lights in a 4' x 4' tent. Two lights sets at 100 watts each and one light set at 1000 watts. Now if you were trying to flower could you run the two 100 watts lights to run for 12 hours and the 1000 watt light for 6 hours? How effective would this...

This is my 2nd Grow,after the first one (4 years ago) was a mess due to my lack of knowledge (overwatering,over ferts, no fan, big fungus gnats infestation, little pots etc...). This time, I want to do better even if I'm going with CFLs...I will try, at least!:laughtwo: I already know that I'm...

Hey guys. I just finished my first grow (need to update my journal, kind of been busy and never got back to it). I had 2 mars hydro 300W LED lights. They are $70 each. I am looking to get 2 more lights for my next grow. The 2 did pretty well for 4 plants, but I would like to do a couple more...

Hey guys! This is my first time around here. This is my second grow. It's a mini-grow in a 90CM height on 60CM wide. Details: Strain - Northern Lights # of Plants - 1 Grow Type - Soil Grow Stage - Flowering Bucket Size - 4 Liter Smart Pot Lights - (2) 65W CFL, one 2700K and one is 6500K...

Yep! I've got two of these covering a 4x8 tray. As of right now, I've only got six plants under the lights. I'm still testing the environment and tweaking controls but so far the lights seem to put out very little extra heat, when compared to vented HID's or even some LED's! They cost...

Oh my... Please add a bunch of these to my wish list. At almost $30 USD per bulb, compared to $6 for plain T5s, these had better be all they are cracked up to be... and if my presently owned and operating Hortilux Blue Eye Metal Halide bulb is any indication, they will be. Here is the...

Anyone else have GAVITA LEP lights?

My recent grow has stretched a ton and has grown all the way into and above my lights. As you can see below my lights are as high as they will go. They are supposed to have a 9 week flower and I'm 4 weeks in and don't see a ton of flower growth either. Has anyone dealt with this before...

Anyone having problems with theese lights increasing room temps? I just set mine up and am getting 10-15 degrees hotter in my room.. Not too bad now but when temps hit 100+ it could be a little scary Just wondering how people are dealing with not being able to exhaust the heat produced by...

i am wondering if anyone has grown the northern lights autoflower in northern canada? this strain is from crop king seeds:thumb:

I have a decent quality headband/headlamp that has clear, red and green lights. If an occasion pops up where I need to get into the flowering area after lights out I put it on and keep the lights out. I have seen green light bulbs, and got to wondering if they would work too. Has anybody used...

Anyone here running a allstart 860 cmh on a digital ballast? It isn't a very good idea if the ballast isn't low frequency square wave. A friend runs 860 on old core and coil ballasts , he said I should expect a 30% increase in intensity and I think he's right. I had a look at his lights...
