I'm having trouble finding a simple explanation of the difference between the Philips CDM T9 and T12. Also, the difference between Agro and non-Agro. Can someone please explain it? I know someone already asked about this on here a few years ago but, I didn't really see any clear answer. Maybe...

Hiya! I'm attempting to grow my first plant and have a few questions.. I planted my seed in a cup and used sunlight for about a week but my sprout started to get too long so yesterday I brought it indoors and I re-planted it in a bigger pot. I made my own set-up in a small cabinet space with...

This is my first grow and I am new here so bare with me please. I have a 36x20x62 grow tent with an unknown plant (I'm assuming its Alien OG since that was the strain I got majority of the seeds I had from) that is a little over 3 months old and a feminized purple kush plant that is almost 2...

New grower and was watching a few starter videos, I always wondered what these things are that connect to the CFL's and haven't seen anywhere what they are called. someone please help - Thankyou :)

I am new to growing and wanted to test some lights out before I spend a lot of money on buying them. Do you guys think it is worth renting before buying them? You know to get a feel for how they work and not be in the whole for a 1k plus considering how much some led light cost.

I have been growing for about a year now.. started out by spending 4 grand on 2 led lights, only to realize that sticking with what's proven was probably a better idea.. so I recently purchased a de 1000w hps fixture.. 400 bux... lol but I am looking into growing on a semi large scale... would...

I am currently researching LED grow lights, Google is hopeless no matter what I type it's just full of paid ads even the ones that seem legit are just ads. I'm not a DiY guy so I'm going to have to spend cash I'm really hoping you folks with experience in this area can help and assist me in...

im going to run 2 DE gavitas in my 9x5x8 tent Scrog. HPS In my last tent with single ended, I mixed the spectrum. For every 600 watts of HPS I had a 400watt mh. This is said to do many things. What are the thoughts on adding a mh in between my two gavitas? If I control heat etc, I think it...

Hello! Can anyone suggest me a couple lights that use generally low electricity, but are still effective? I am doing a stealth cupboard build and electricity will be limited. I plan on only growing 2-4, short plants. Thanks for all the help!

Hey guys, currently working on a new setup and it will consist of two 3x6 tables on one wall. So pretty much 12 feet of flood tray with a foot of space in between. Just curious what lighting everyone is using for these smaller tables, im open to anything but looking for the best yield. Thanks

I had one HPS and one MH bulb. rotating girls to give them a variety of intensities at different wavelengths. (mature vegetative state) Recently my MH bulb stopped working (i think due to some unintelligent methods of plugging and unplugging ballasts and such when rearranging. not the current...
