lights

Okay so the problem with LED since it came out was its extremely high cost per usable watt. But now that the prices of LED's are beginning to compete with HPS and MH setups why not switch? Especially if you're savvy about your purchases. It is much cheaper to set up a room with LED's than with...

So I started her roughly beginning of Sept, popped up Sep 15, web says about 65 days to harvest from sprout. I'm letting her go to 70. She's a beaut. Little scent, lots of branches for as small as I kept her. She's roughly about 18-20" tall. Lst'd early on. Scrog in use also. Ff lineup, with...

Hey guys got referred here from reddit's Microgrowery. Basically getting a 4'x4'x7' grow tent and planning on putting in LED lightings instead of the traditional HPS system. I was going to do a DIY COB build but since its my first time growing, I figured I should just start with pre-built...

Like most newbies I started out with a grow box and some CFLs. As my knowledge grows, I keep upgrading my equipment. I now have a 2.5 x 2.5 x 5'5" grow tent, and I am looking to maximize my yeilds in this tent. Since the amount of light you have directly effects your yeilds, is it safe to...

Hello rollitup growing community, I have just finished my first set of DIY grow lights. Its a simple setup for a 2x3 or 2x2 grow box. I am using an HLG-185H-C1400B driver, currently 2 Cree CXB3950's and some cheap but silent Alpine fans on two separate heat sinks. My driver runs at an operation...

I have a 400 watt hps at 16in away from top of plants and it's a constant 70 degrees and 50 percent humidity could this be moisture stress?

I'm looking to purchase some led lights from Neonica's Growy range, however I can't seem to find any reviews etc on the forum or elsewhere! I'm thinking to use maybe their smallest bar style light or posssibly their 100w version. Probably going to scrog in a tall 60cmx60cm box from rooted...

I took apart my old dlp tv and took out the defuser/magnifier and using it to boost my lights. If you think about it a tv needs to focus the light so I can see the show in full light at 20 feet away. Here are 2 pics of what they look like, I've got video but don't know how to post to show where...

Does anyone know how wide NL Auto tends to get? I'm considering using it in a SOG. I see that it can grow to between 90 and 120 cm. Just wondering how many I can have per square foot. Do you think 1 per square foot would be acceptable, or should I give it more room to breathe?

so having a debate right now my husband is scared to switch over to the led but i think it would be a lot better cooler and save money..... what do you all think?

My lights went off after 3hours of being on during the 4th week of flower they stayed off for roughly 6hours before i realised.i have left the light off now until they are due to come back on again in the morning.was that the best thing to do.or should i have turned them on and carried on as...

Hey all, I am now about two weeks into flower and realize I should had tied some of the plants. The light is at max height and I'm worried some heads might burn. Could I still tie some down or is there a "light shield" type thing to help dim the light? Cheers!
