Things to Know About Lighting

I have a quick question, what would you consider using for flowering?

I've used hps and had successful grows, but I heard t5s had lights for blooming stage as well and will consume considerably less electricity.

What are the positives and the negatives for a T5 and HPS?

Thanks in Advance.

Do you know if those 0.6 bulbs nvm. I need to get a place to grow
Im thinking colorado but I dont know.
I dont even got a computer to use, this one isnt mine. Thats why I cant really get my grow set up. My parents found the grow I had set up in a hallowed out dresser. Thats because they got a key to my room because the fuck head cops gave her my keys. They where supposed to just give her the key to the car. O well, cant cry over spilt milk, I never would have made much money with it the way it was. Full of nasty ass dirt that well had pretty much every possible thing in it except what should have been in it. So I got all that cleaned out now but still cannot grow there because I have no motivation to grow there anymore. Im now thinking about growing outdoors on a near by indian reservation. Ive already driven threw it a few times and got a pretty good feeling about where I can get some water. The grow area is going to be super high tech camoflagued so that I only have to worry about traps. Traps will be things like electric fence and shit. Ive been thinking about rigging explosives to some of the ones that I got hanging on trees in my mind. Its just an idea forming in my mind for if I discover that there is a lackey in the area. Unfortunately for one thing is that I do live in ND. If only I could live somewhere like columbia, and just have my own farm. Even buy an island like Hawii, and just grow my crops there and ship it out to where evers esyest. Shit I dont know how to spell. Got to learn how to live with it I guess, not like Ill be living much longer. I treat my health so bad that I got to pop. drink pop. god I dont know what my mind is doing here, Im supposed to be talking about how I am saving up money to buy an Ipad2 so that I can have my own computer so that I dont have to worry about the shit that Im s

Will yeild be less if you put seed into 12/12 from the start,just wondering as ive done this with a blue mystic,she seems to be just growing as well as she would under 18/6,she is about 3 weeks old and she is already 12inch,just want to no if my yeild is gonna be affected by this,thanks and peace out!!!!!!

That is sort of a broad and vague question. It leaves out a HID light with a switchable ballast that could use a 6500K or 7200K MH bulb for vegging besides a HPS for flowering and it does not mention the possibility of using a HPS bulb with an enhanced blue spectrum during flower and it does not mention the wattage of the HPS you want a comparison to.

Unless you are talking about a low wattage HID light you will get a whole heck of a lot more light penetration from a HID light than from a T5.

Thanks for the post. I firmly belive that lighting is one of the most important things to get dialed in one in a new grow op.

I like to veg my plants in t5's for a month then flip them. 1000W HPS takes them right up until harvest.
It's cheaper and it produces great results
Four wks veg time then as many wks flowering time as they need.

I just got my first 3 germinated and they're about 2'' tall... What temp should it be around my babies? Last night before bed it was 75f , when i got up and checked on them this morning it was 86f but i had a 6'' fan blowing a light breeze around them. Being my first grow that temp worried me because they looked { not wilted but a little droopy}. I really got more light then i need,, i have a new 400watt hps and a new 400 watt mh light that i wanted to try out, so i been burning both and have had to keep them about 4ft. above the plants so not to over heat em.

im on my first grow and ive got 14 plants; 6 under one 150W HPS and 8 under another one. they are all on a 18/6 light schedual. about a month old range from like 8-10 inches tall each amd very bushy. most of the stunted growth was just cause from topping. actually FIMmed one of them lol you dont need any super special lights if you know what youre doing.

i've currently got not much more than seedlings, first 4 individual leaves and have only got a couple of day-glo bulbs at the moment, they use 25W but put out the equivalent of 150W each. i'm waiting on a 2ft 24W CFL 6400k striplight thing arriving. its my first full grow, just using the spare bedroom. i'm not using traditional lights, my striplight is coming from jungleseeds.com (friend of a friend suggested it) i think i'm just a bit worried for my babies, couple of questions, is it enough light for a half decent veg state? goin to be buying the blue spec light and reflector for the flowering stage. my other question is can u have too much light in a room and what sort of side effects would you get from too much and not enough light? the seedlings are growing fine at the moment, slightly stretched stems and a slightly bigger root system due to my foolish watering system earlier. i'm learning quickly lol

Ventilation is key, especially if you are in a small area. Make sure you get cold air in, and get that hot air out. A small intake fan should do the trick, if placed in the right spot- just experiment with it.

I used a $10 vent fan for aircon ducting...not so strong, but kept my temps down enough.

got a question for anybody willing to answer, I have two 150 watt hps running for 5 plants in a 2 metre square space is this enough light to produce an decent yield?

For flowering you are going to want a red spectrum light like HPS or 2700K CFL. Blue spec like MH or 6500K CFL are better for vegging.

I agree with BCENVY don't steal lights from construction sites. That is just stupid and highly illegal and if you did that around here you'd probably never be heard from again. Remember what goes around comes around!

Karma is a bitch!

I think I've wasted a lot of good seeds. I did not allow them to germinate enough and I threw them in the soil under a 400 watt Mh, that was to close to my green house. I moved it farther away later on in the day. Anyway, the next day I switched to this light that I bought http://www.walmart.com/ip/Lights-of-America-24-Fluorescent-Grow-Light-Fixture/16879945 for like 10 bucks. From what I have read these "grow lights" are garbage? So from what I am reading on here I need the cool white cfls or I need some kind of t5 light? Is the flourescent light I'm running now good for anything at all? I have 9 seeds under the soil right now the last 3 days, I don't think many of them will make it. Should I buy another 10 dollar light or do I need those cfls? I already have the mh and hps for the later stages, I just need to have enough for these seedlings. Also this grow light I am running has plastic cover over it blocking direct exposure from the bulb, should I remove it? Thank you guys, its been stressful.

Which of these from walmart do i need? http://www.walmart.com/search/search-ng.do?search_query=t5+light+bulbs&ic=48_0&Find=Find&search_constraint=4044
I've been reading on here all day and I am still confused. What lights should I add to my 24 inch flourescent light for the seeding stage thats lets off 1000 lumens, possibly into some of the vegetation stage? I just need enough to get them to sprout and grow for a short time before going to mh and hps. I think I've pretty much wasted my seeds, I tried so hard too. I don't want to buy any more flourescent lights if they are no good.

Can anyone tell me if any of these would be good? Maybe something like this daylight 32 watt t8 bulb. http://www.walmart.com/ip/GE-4-Daylight-Fluorescent-Light/16880855 If anyone can give me any kind of confidence boost in what I'm doing it would be appreciated. I would like to get by without having to use the 400 watt metal halide for as long as possible. Right now my cups of dirt are getting 1000 lumens at 4200k color. I would like to go up to Walmart but I just dont know what to buy.

Great thread

You'll get waay better results over-all if you grab the phone book, and look in electrical, or lighting section of the Y Pages, and ask if they carry 175W MH or HPS ballasts.. If they do, then they'll also carry sockets and bulbs.. You can get a kick-ass light from places where contractors would go to buy stuff for about $50 total and your results will be MUCH better..

Yup yup...I'm a general contractor...they are in fact all over large construction sites.

HOWEVER I HIGHLY DISCOURAGE STEALING FROM CONSTRUCTION SITES...IT'S DARK, THERE'S NO ONE AROUND...THEIVES THAT ARE CAUGHT ARE GENERALLY DEALT WITH SEVERLY WHEN CAUGHT IN DARK PLACES WITH NO WITNESSES.

BESIDES IT'S JUST FAWKING WRONG TO STEAL AND ALMOST AS WRONG TO CONDONE OR SUGGEST IT. BAD FORM MY FRIEND, BAD FORM!!!!!!

and on a more personal note...thanks, it's people like you that cost me hundreds of thousands of dollars a year replacing crap I find stolen, you know we can't work when you steal our stuff?!!?!?! Oh and those lights, that's called EGRESS LIGHTING, it's sole purpose is so we don't trip and kill ourselves at 5am when the fawking sun isn't even up yet. And when it's not in place OSHA comes and shuts down our job site because we are then in violation of federally mandated construction safety laws!!! Makes me sick when I have to be woken up by my Foreman because someone stole from our job site!!!!

YOU WANNA GROW POT FINE...DON'T STEAL FROM HARDWORKING PEOPLE TO DO IT!!!!!!!!!!!!!!
