As promised, here's a bunch of pics of my equipment. Now nobody can call bullshit on me anymore. :rolleyes:

the ceiling shots are of the IR-blocker

The carbon filter weighs 125 pounds (I was curious so I sat it on the scale, heavy motherfucker.)

Also pics of juvenile plants and seedlings.:leaf:

-----ON TOPIC-----

My seedling mix;
50% perlite
40% sphagnum moss
10% peat moss

Planting and watering; after the seed pops open, I plant in a 16oz solo cup with 4 holes cut in the bottom for drainage. I fill the cup with the soiless mix, and water the hell out of it with plain pHed water. Give it a good rinse. Then let the excess drain off.
I plant the seed a cm from the top of the soil line, taproot down, and put a little of the mix over it.
MHM--Sounds like a very interesting grow and I look forward to learning some new tricks and gaining some new ideas. I use the same seedling medium mix but I add 1/2 teaspoon of dolomite lime to each cup and work into the soil before the first watering since the peat is so acidic. A couple of tricks with 16oz plastic cups that I have found to work great is 1. Only fill the cup with 4 1/2 inches of soil(The watering method you use will pack it down to 4 inches which some believe to be the magical depth for the tap root to grow and produce more females than males). Then after a week or two you can fill in around the stem to give good support without the need of stalking-Then only time I usually find the need to stalk is in week 4 of flowering. Another fun trick that works well if you have the extra time is the double cup method with the inner cup being clear--You can get a really "CLEAR":lol: idea of how your root-system is growing and the effects of your feeds. Anyway---look forward to your posts:bigjoint:.

Insightful post, I've used clear cups once, but had a lot of algae growth, good idea putting it inside another cup, too late now, but a good tip indeed :bigjoint:

I was going to use some dolomite lime, but couldn't find it, and time was of the essence. I don't normally use it for bloom, because the nutrient ph handles the acidity level of the soil.

I started out with the bone/blood method back a long time ago when I was 16 growing outside for the first time with the guidance of Mel Frank's Marijuana Growers Guide, old school. :bigjoint:

I did the blood/bone meal for a long time until everyone went crazy about mad cow disease and shit:wall:

Nice looking dogs :bigjoint:

The one on the right looks like my dog's mother, her father was a 145# brindle.

She a mix of the two, a light brindle pattern with more fawn than usual for a brindle. She weighs 95#.

MAD COWS!!!! I remember that, it was right around the time I stopped using bone and blood too, that was like '96-'97 right?

Sounds about right---I don't want to hijack your thread just saw your boxer and wanted to post a quick pic of my kids. Anyway sound like your going to have a nice room when all things are said and done-it seems that things take at least three time what you think they will. It's fun thou and it's just part of us I guess---I would still grow even if I didn't smoke---I just love the plant and have since I was 13. I grew 1 male up in a attic in a closet----I would jump up and grab the attic access hole and pull myself up in there for hours---I didn't even know what 12/12 lighting was or even male/female plants-I remember the phototron just came out in HighTimes---My sister ratted me out and I had to dump the plant---I was sooo pissed---but that was the start of something else:mrgreen:---that was the summer of 84'. Time flys...:peace:

Time flies, that it does, and whoever thinks marijuana causes memory loss is retarded, because I remember those days like they were yesterday!

Yeah I forgot how long seedlings take to grow...

Howie,
U usin just one centrifugal fan to aircool all of those HIDs?? is that enough air goin on to cool them all to the point where u can get them nice n close to your girls???

Im askin cuz i was planning on using my old growbox as a veg chamber until they got mature enough to move them into my tent n blast some HID light onto them, n im still definitely gonna use it for veg so i can do a perpetual grow on the constant, but for my 1st grow with good chronic from seed, i wanna have my MH on them for as long as possible before i force flower. once i start my cloning ill use the veg chamber, but for thisone, the sooner i can move them bitches in, the better.

so is the one enough to cool them all??


OOOO also,i wanned to ask someone this, and since your pretty knowlageable i may as well ask you - Is there anyway i can retrofit my ballast somehow so i can hook up two seperate bulbs n reflectors to it? like, lets say i have my 600w ballast - is there any way i could hook up two reflectors to it, each with 250w bulbs, and then maybe a hookup for a 100w HID that i could just hang in the middle of the plants??

No, you can't retrofit a ballast to operate that way.

You can run two lights off one ballast in seperate 12/12 rooms, I ran 12 ballasts on 24 hoods seperated into two seperate rooms.

To do this; you need 2 two-way switches. You run the power through them both, and only have one switch on at a time, the leads from either switch go to a seperate hood. There is a automatic version with a built in timer that costs a lot of money compared to two common household switches.

It was a bitch having to manually switch the lights every 12 hours.

--Yeah that one centrifuge fan vents all the hoods, pulling air through 3 and 3 then "t" into the fan.

It's a really high CFM fan, I'll check the numbers and let you know, but it was the biggest I could find.

It's the CanFan 150, the link doesn't work...

It pulls 900 CFM of filtered air. :mrgreen:

Pretty powerful. :bigjoint:

It sounds like a jet engine when it starts up.

The other centrifugial fan is a Sunleaves windtunnel, it runs 480 CFM of ambient intake air, and the squirrel cage is for pulling excess air out of the main return in the house's HVAC.

Thanks man, I should have everything setup and operational in the next week or two, but it'll be a while before I start blooming.

I'm thinking a harvest probably right around the new year, hopefully earlier. But I'm guessing it's going to take another month before I'll have all the clones I'll need. :bigjoint:
