cmh

1st off i suck at writing! bongsmilie:bigjoint: I decided it is time for a different thread as the last would not represent my room anymore. I have made the CHM/LEC plunge full on, replace all the HPS/MH with comparable fixture as what i had before. This will be the beginning of my try at...

I currently have a grow going in my 3'x3'x6'11" tent. I'm using a 315w CMH light. A friend of mine gave me his 2 MarsHydro 300 LED lights. Would I be able to use these in any way to help increase possible yield, or should I use them as door stops?

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, just started my first grow, and I'm already in trouble. My current setup is a 3' x 3' x 6'11" tent. I have a 6 inch intake fan and a 6 inch exhaust fan. My light/reflector is the Phantom CMH 315W. The reflector is uncovered (no glass lid), so it is running a bare bulb. I've had the...

Newb question. Got my tent going yesterday. Noticed that the light flickers, is this normal with a CMH bulb?

I definitely want to protect my eyes, but at the same time I don't want to break the bank for eye wear. Thankfully I don't care if I look like a tool, so I'm looking to pay for function as opposed to how rad it looks. Would these be suitable for use when working around a CMH light (315W)...

Alright, here is an embarrassing question. I ordered a kit that was supposed to come with a CMH bulb 4200k for vegging. Nowhere on the bulb does it specify that it is 4200k. With Philips, how can I tell if the bulb is 3100k or 4200k?

I finally pulled the trigger and bought my grow light. Decided to go with a CMH. The unit I got has a vertical bulb in a reflector, but with no glass cover. https://blueearthsustainable.com/grow-light-kits/phantom-cmh-reflector-ballast-and-bulb-kit-4200k-phr31504kt So here is my question. In a...

How long do CMH lamps last compared to HPS?

This is my wife's grow at her house, 12/12 plants they go in 6 at a time so every 5 weeks get a chop. Quick run down of Flower is 13x11 room (12' ceilings), 6 1000w DE Gavitas and 4 Gavita 270e's, each group of 6 plants goes under 3 1000e's and 2 270e's. Running 1000's at 73% power (Yes I should...

I currently have three vegging chocolate rain and one chocolate cheese (received two of these freebeis) from eskobar seeds. Unfortunately one of these was a runt, which was a pain to cull as I'm only running four plants here. The fifth choc rain seed appeared light in color and small/immature so...

Hey guys, I ordered a 600w hps and it's in the mail, I got it for $90 total. Dimmable and digital. I just found this 400w CMH from HTG SUPPLY. Which one of these two lights would you recommend for my 5'x2' flower area, and which would be best on heat and noise? Im new and it is my first grow...

Decided to start a journal just for the here and now, it'd be nice to have a place to come post pics and stuff again. I did my first journal (in my sig) from february to june/july of this year. Had a great time with it and haven't stopped growing at all, just stopped posting it a lot on...

Hi all, mentioned in my last thread that I'd be consolidating my threads and journal/blog posts into one thread. it just makes it easier than trying to run multiple threads/updates in different locations. I rarely change my avatar, but a very nice gentleman here @ayr0n with some great design...
