Just think... If HPS produces more lumens per watt then the assumption can be made that it burns cooler. Since more electricity is transformed into light, then less electricity is left to produce heat.
I could be wrong on this. But none have corrected me on it.

I think I have heard that somewhere and it makes total sense. This would also mean I would have to have an external ballast located outside of the cab. Its something I definately want to do in the future, but I think I am going to stick to CFLs unless I can get a HPS for around 60 bones. I know there are some security lights at HomeDepot, but I'm not so sure on trying to make a reflector and mounting for one of these.

Im about 250 deep in the cabinet now, the costs add up a lot faster than I was expecting. All I have left to buy is nutrients and seeds.

I feel you brother. The cost adds up very quickly.
But when you taste your first couple of dried/cured O's, You'll be singin a different tune LOL.
Then once you add up what you save in herb cost, You'll know in your heart.
Just think...2 O's of "the good" cost around $600-$800.
Till then, Good luck getting there.

For your first one, it's the thrill of the grow, to have fun, to learn things, and maybe you'll even get a little weed out of it.

I would definitely paint the insides with flat white, or put some mylar in there with a non-explosive spray glue. I don't know how much light is absorbed in the tub before reflecting back, but any absorption there should not be. Glossy concentrates light in certain spots instead of diffusing it as flat does.

2 cans of paint - $8
Increase in 1st yield as opposed to now - $16 worth of weed. Exactly.

Its been a thrill so far, and I don't even have my seeds yet.

If I can get two ounces of dense buds out of this first time grow I'll definately be singin.... lol Hopefully the taste will inspire a HPS for the next go around !

Actually bro, its gonna be density that inspires HPS. :(
Unfortunately for us CFL users, The intensity isn't enough to produce the most dense buds. My indica came out pretty dense but the sativa was very airy. I think cause of the light requirements for sativa are higher. I noticed that the indica wouldn't survive in direct sunlight while the sativa seemed to soak it up and love it.
Keep that in mind when you decide on strain. :thumbsup:

My understanding is that in general sativas are more fluffy and airy, so that makes perfect sense. But what do you mean that indicas don't survive in sunlight? They grow in sunlight all the time, so I'm confused.

I have a question. If i were to put 12,100. Lumens of CFL Light's in a 22 Gal. Rubbermaid. Will that be enough Light to Flower two plant's?

ahh sorry about that, I meant didn't survive well. And I should mention that the sun here(SouthUSA) is intense and hot(95F-115F).
Both had to go outside one day while my power was out. And to that effect the indica looked horrible when I brought it back in while the sativa was standing straight and just generally looking healthy.
At first I thought it was all from heat stress. So acting as a true scientist, I set forth to prove myself wrong. I put both of them in a window that receives great light and found that the indica still looked pretty stressed after one day.
I imagine that after a week or so they would have adjusted to the light.

And I had no clue that sativa's were supposed to be more airy. But now that you say it...
I was under the impression that the only limiting factor in density was light(not penetrating enough).

Wow, 115? My condolences. I can imagine that any plant might not survive in those temps. I can see now what you mean, since I kinda thought most MJ plants won't survive anything over 105.

I've never heard that before about indicas, and I thought I knew everything. (kidding) Does that have something to do with what part of the world they came from? Always lernnin.

actually yes it does.
Sativa's have more "accessory pigments"(thats why there a bolder green). That pigment allows them to easily adjust to intense light, Indica's are short on that pigment, thus they need more time and more gradual shift to greater intensity.
And yeah I was surprised too(115F) but, in mexico it must be hotter, and they've got tons growing. from what I understand, they grow mostly sativa's for the brickweed "you" get.
I would imagine that both would have at least been stunted by 115F. But my thought is that I don't have a 100% Sativa strain. and they do.

damn this turned in to a pretty good thread. thanks for the info zcomp. c99 is a heavy sativa right ??? I was really liking the look of it, with the low odor and all. but with cfls and a scrog setup, what seems to be the best indica dominant strain ?

I have no power to grant any strain the title "Best". But if I were to name a couple that I like.... White Widow or White Rhino.
What ever you pick remember, Your first grow is probably gonna be stunted in some way, Don't judge a strain until you've worked with it enough to bring out its full potency. That could take 2 or 3 grows of the same strain. I've noticed that each harvest of a strain gets better and better as you learn what your strain likes.

I have heard c99 requires a lighter amount of nutrients. Would this mean I could cut all strengths in half. Meaning, instead of 1/4 strength nutrient for young clones it would take 1/8 strength. Full strength for flowering would then be 1/2 strength....

Is this something I could go by ?

Any light is enough to flower with. But do you want any weed for your efforts? I would want more light than that.

This is the wrong section for that question, but... what do you mean best? What's the best car? What's the best pizza or ice cream flavor? What's the best sexual position?

These questions and the one you asked are subjective. That basically means it's a matter of opinion, and they could change at any time.

This might help:

opie's right. Dodge Viper VR4 Twin Turbo, Sals pizza, cherry garcia and doggystyle are just my opinions. They might change later tonight.

True, but I was suggesting more of a strategical approach. Eg. Using a indica strain because of their lower light requirements, (as zcomp suggested) Also, using a branchy strain that is easy to train. All strains have their ups and downs, and I would like to find a strain that its ups matched the needs of a CFL hydro scrog. I didnt really ask for the best general strain, I set constraints. If I asked for the best 4 wheeling vehicle, surely you wouldn't tell me a dodge viper. Contraints are important. Potency is not one of my constraints, my constraints are: Low light requirements, branchy, etc. C99 seems to be my winner, but zcomp mentioned that sativa dom strains do not do as well with cfl lighting.

If this thread needs to be moved it would be fine in my log thread, as it pertains to most questions I have had about setting up my grow.

You've got good taste. I don't know Sals, but Yes! to the others. I've lusted after the Viper since it first came out. Always choosing the Viper in video games.

thex420, in that case, you're defiantly going to want an indica. Did you click that link about the best? Take your choice. Most any you can prune, LST, FIM, top, or whatever, to make it do what you want, screen or otherwise. Some don't like it, but most will tolerate it if you try to be gentle. One of the best way to find out what individual varieties do is to look at what seed sellers have to say. One place I often look is Marijuana Seeds (cannabis, pot) shipped worldwide.

Yeah dude, I fell in love during GT3 When I hooked up over 1000 Horse. Then my friend working at a dodge dealership took me for an orgasm inspiring ride. I'll never stop reminiscing of that day, The day I became a part of the seat going 0-60 faster than I imagined a car could.

Thex420, Opie's right on again. Pick an easy cloning indica. If you want it a little leggy, look for an 80/20 I/S or 60/40 I/S. Light amounts are subjective, the more light the more bud. on any plant. After your first harvest, decide on how much more you may need.
I can tell you with confidence, My indica bagseed produced huge buds under CFL only, and in dirt. Its possible to do anything.

Perfect answer, thanks man, just what I needed. Might just drop the whole c99 thing, and just clone this nice looking indica my buddy has growing right now. Short and bushy, Just ask for a clone and start there. Goes good, then buy the sweet cindy. I am still going to grow that bitch sometime in my life time :)

Might try aero bubbling the clone, looks like a pretty sure fire way from what I have heard on some bubbler threads.

air stones, pump and tub on the walmart list tommorrow..

Is there someway I can get this posted my grow thread, its pretty much my log so far.

This got too long, BAKED.

:stoned:Im out !:stoned:

You could copy and paste what you think is important, or provide a link to this thread in your log.

Yeah I use the aero cloner myself. Just tap water(declorinated) & SuperThrive and 100% success thus far(12 clones in). Takes about a week and I use low intensity CFL's with a humidity dome. Once roots appear I replant in soil.

IMO, that is the best way to get a high success rate, and big beautiful gobs of roots.
