lighting question

Hello! I am about to take on my first grow and was wondering if using white aluminum trim coil would be a good reflective material for my diy-cfl-light-hood. I remodel homes and have plenty of it laying around so I was considering using it to make my own reflective light hood. I’ve seen posts...

Hi! New member here. :) I started my first grow using bag seed, so I don't know yet if I've got a female or whether it's autoflowering or photoperiod. I'm using a 5-gal space bucket set-up with 4x 23w CFLs (18/6) & supersoil (I have a 180w UFO LED ready to go for flowering). It's coming up on...

I know this might sound crazy but I wanted to see if anyone has tested or seen research that compares the lights vs different types of strains. Considering how the strains grow differently (width, height) would an led light work better for sativa plants since led par levels do not get spread...

Hey guys. So heres my situation. I bought a 125w set up and ended up changing the 125W bulb to a 400w bulb since I had 4 plants growing and knew i needed more wattage. What I didnt realize since indoor growing is new to me is that apparently my ballast is a 125W magnetic ballast. Iv had the 400W...

Looking at best lighting for low costs, heat and spread to run a 2*2 meter tent, seen many reviews and growers talking about gravita lighting and mixed reviews on others too. Any advice would be appreciated? Cheers

Well I'm also a new grower. I have the usual questions and usual probs. Although my first harvest was not a huge yield, the potency was through the roof. I'm trying to figure out if 1 400 watt setup is going to do it for a 5"x3" area. (I may expand the grow space depending on what I hear.) I'm...

So, I am setting up a small grow in a closet that measures 7 ft deep x 4 ft wide x 7 ft tall. I am using a. DWC system that I built a few years back. I have a height-adjustable 1000 w HPS light that will hang from the ceiling. I am wondering if this light is going to be too much for such a...

Hey peeps Basically, i have a small space where im thinking of growing in ( Around 1.5 metres in height ) I know using a large lights , 400w , 600w etc is going to be to hot. Iv been doing a little research and iv seen that autoflower plants dont need big lights as you would normally use...

i will be flowering starting next week...i just want to know when i should switch my lights to the soft white....i'm doing a CFL grow. someone told me that the first 2 weeks of flowering are closer to a vegative grow then flower, so leaving the 6500k would be better for the first 2 weeks of...

I have a 400w that i will be installing. I am 21 days into my grow from seed. Running 18/6 during veg. How high off the plants should the light be?

...for about 4-6 plants in a 5'x7" space? Would this product be sufficient? I am considering buying this. Amazon.com: 400 Watt 400w Digital Switchable Ballast Grow Light Set Includes HPS, MH Bulbs, Reflector, Power Cord and Hanger, GYO-2002: Patio, Lawn & Garden

Hey Everyone. Newbie here and I am in the process of building a grow bow from an armoire. It will have two chambers, one for veg and one for flowering. They will be totally sealed from one another within the same box, not light, no air will be transfered. I think it is a no brainer that both...

A lot of people have a lot of opinions on indoor lighting. It always comes down to lumens and it seems like the more lumens you can produce the better your crop is going to produce. I've looked at 4 foot 8 bulb T5's. as well as 400W 600W and 1000W lights in vented hoods. However, a lot of what...
