reflector

So Im getting the last few details together on my 3x3 setup and was wondering peoples opinion on whether they'd leave the COBs bare, use the LEDIL reflector, or use the LEDIL reflector ? I know a lot of people lean towards the reflector, which works perfect for 6 COBs in a 3x3, however Im...

I'm currently working on a light for a 4x4. The goal is to get a pretty even 900-1000 µmol m-2 s-1 across the whole space running it at 500W or less. The COBs are Vero 29, 3500K 80 and 90 CRI. I took some measurements with an Apogee SQ-520 today. At 40cm distance, I get a bit over 1k in the...

Hello everyone, this is my first actual grow. I’m using cheap soil that I mixed up from Home Depot with a little bit of worm castings I harvested myself. Seed is a blue dream bagseed I believe and am growing it mostly to build the soil life. Seed germinated 9/16/18 and was planted in half peat...

Hey everyone, first post ever. Just getting back into growing now that I'm off parole and no longer property of the BOP and well let's say I'm starting from scratch, and on literally $100 at a time or so. Money is tight until I get going, but I have enough experience under my belt I've made do...

Hey everyone, I am needing some help here.I have 3 working marshydro led fixtures but would like too convert too cob style lights.I took a couple pics of my marshydro reflector48,and pro II 80 and need help choosing which cobs i can use too convert these lights.I did a search and couldnt find...

Hey guys, so Im doing my first tent grow. Just a small one to start and see how she goes. Im hanging a 200w CFL with a reflector. When i screw in the light there is a pretty mean hang to the socket and the whole light bends an inch or so down. Has anyone had this happen to them using the same...

Right now i've got two 600w hps in the flower room, i'm looking to upgrade my hoods. What hoods are quality doesn't matter the price. just looking for suggestions. Right now i just have the cheap wing reflectors. Thanks

Hello guys, Can I ask you what's the actual range of the 600Watts HPS lightning bulb and reflector? I found like a lot of information one saying it it 2x4ft one 4x4ft one 6x6ft..I got confused so I decided to finally seek for help and ask you out guys, I know it depends on the reflector and...

Shortly gowing to be running 4 Cree cobs fitted with angelina reflectors. Would it make sense to wrap the outside of the reflectors with aluminium tape so all the light is reflected out and down rather than leaking out the sides?

I'm using a 315W CMH, and was wondering how much UV will I lose if I use the glass lid on my reflector? Also, is it important to have UV throughout veg. and flowering, or does it become more beneficial during late stage flowering?

Alright, newb question here. I'm having a terrible time figuring out where the charcoal filter/odor scrubber should go. Is this order correct? Duct --> Intake Fan --> AC Reflector --> Duct --> Charcoal Filter (air expelled outside) Would I need another fan (lower CFM than the intake fan) to...

Any thoughts on the science behind the effectiveness of a vertical light/reflector? Specifically I'm looking at the OG Vertical Reflector by GrowLite. I've read a few negatives regarding it's spread and the vertical height it needs for clearance. Luckily I only need a light spread of 3' x 3' and...

Would the Blockbuster 6" Air-Cooled Reflector be a good choice for a 3' x 3' grow tent? I figured it'd be a good fit since it is designed to be used with "squares", but figured I'd ask and see if anyone has an opinion on the matter.

I was curious to know if anyone has an opinion on the veg. and bloom switch on the MarsHydro Reflector 192. Would there be any marked benefit to using the individual modes during the proper growth phase, or would I be better off just running full spectrum the entire time?

Yes, I know these lights aren't the best nor are they the worst. I had planned on just going with a HPS (can't afford the nicer COB LEDs), but a friend of mine has a couple he's looking to sell. They have gone through 2 harvests. Given the price point he's offering me, they're a good enough deal...

Found three types, want to know which one is the best when growing marijuana?

I got one of these from my hydroponics store http://www.amazon.com/Sun-Blaze-Output-Fluorescent-960315/dp/B009GCQWX2 This is just for my seedlings. Has anyone made their own reflector with one of these before? With the seedlings would the reflector matter?

I have 2 Mars hydro 192x5 reflectors. They say one is great for a 4x4 tent with the light 24"-30" above canopy. I have a 5x5 tent so I thought, why not get 2 and make it more than enough light. So if hanging one in a 4x4 tent at 24"-30" what do you think would be an ideal distance for 2 in a 5x5?
