400 watt club...

[Maj.PotHead]

I would go with the 10 girls in the 2 gallon grow bags. You might be a little cramped, but you'll probably get more than 8 spaced further apart.

ive been thinking the same i built a 19in x 46 inch scrogg screen {chicken wire} it's 10inch above 2 gal bags and 31.5 inch below the light in the above pic is 10 girls. but i still have few more waitn to see the hairs then i choose the 10 best, all of the girls show a very strong purple color in main stem leaf stems and purple hues in the leaves. and the purple isnt from any defficincy its genitics 100%
was last oz in a lb


i smoked this stuf most of the winter every time i smoked it i got as high or higher then the 1st time on this strain i honestly rate it 9.5-10 ive had batchs on both levels lol. it is a couch lock high if you dont do anything after you smoke lol the smell is good sweetsmell hard to explain. the odor during veg right now dose fill the house if im not burning incents smell security isnt much to wrry for me pluss my home either smell like incent or white sage burning. i like to burn sage it's soothing to my spirit

so scroggn 10 girls it will be

Good looking buds everywhere folks. I'm joining the 400w club. I've been growing with 250w of CFLs for 3 grows. Now it's time to step it up a notch. I ordered my light yesterday and it should be in place by the weekend. I'll still use my CFLs for side lighting (if temperatures permit).

Here's a couple of shots of the last crop under the 250w.

Hey Reverend Willis, how many plants in how many square feet? How much did you yield per plant?

 

[Guest]

C25 400W here. (see sig for more)

Hey Reverend Willis, how many plants in how many square feet? How much did you yield per plant?

Hey YG. I grew those in a converted bookcase cabinet 4 ft x 1 ft x 2.5 ft tall. There were 3 girls in 2-gal pots. I averaged 22 grams from each plant. That's about 2.3 ounces of nice bud. With the 400w, I'm moving out of the cabinet and into a closet so I can get some heighth on the next crop. I'll veg with the CFLs and then toss them under the HPS for flowering.

Question ::::::::> What size footprint will the 400w provide and still be the most efficient? 4x4? 3x3? I see 400w gardens with between 2 and 42 plants in them. I want to do a perpetual garden salad with different strains. Right now, I have a WWxBB and a WW (Female Seeds) almost 4 weeks into flower. I nearly killed them with Superthrive. (See pix below) I also have lots of clones at different stages as I am trying to learn how to root and grow them.

 

[Guest]

The 4x4 footprint would probably be the most effecient as far as production goes. That would be like 25 watts per square foot...

hello all,everyones plants look good!i have been thinking about getting a 400 watt hps,i get between 110 and 120 grams of nl/ww under a 150hps.how much increase do you think i could get under a 400 watt hps.everything being equal?could some of you guess or say how much off 1 plant you get.thanks all and grow good!

Hey everyone, I have a Q about vegging with a 400 MH, My Flower cab has a 400 HPS and a 150 HPS, I just got a 400 MH for my veg cab, I was wondering is the same rules apply as far as how close to keep the light. or can i back off some for more coverage. I had 2x 150 HPS in my veg before.

 

[- ezra -]

you shold be able to back off a little. keep in mind the mh produces more heat than hps, but also more light in the spectral range used in veg, so it should be more efficient in veg despite overall being a less efficient lamp (does that make sense?)

Hey Boz. I found this chart for distances. I was wondereing the same question about HPS lights.

That sounds really good. I'll probably go with a 4 x 3 footprint. 12 sq. ft. should be plenty.

Another question... If the garden is 4x3, will the direction of the hps bulb be parallel with the longer sideof the garden?

 

[- ezra -]

no the bulb thould be parallel with the short side for maximum efficiency.

 

[Reverend Willis]

no the bulb thould be parallel with the short side for maximum efficiency.

Thanks, Ezra. It makes perfect sense now that I can see it in my mind.
More light is emitted from the sides of the bulb. Doh!

Yea, thanks ezra. makes sense. I'm pulling these 150's out. Cab is 15" deep and 30" wide


Rev, thanks for the MH chart first time I've seen that one

Right on everyone looks like the 400 watt club is taking off. I always like to have another thread dedicated to sweet flower shots. So lets keep it going by posting as many 400 watt grows possible.

 

[Guest]

Right on guys, nice thread! Count me in!!!

Here's a little motivation for all you fellow 400 heads, more than 8oz from a 4.5 sq ft closet. Keep it green everyone!

[BennyBlanco]

Nice User Name...I also got a little over a half piddy out of my last 400 watt grow

 

[bostrom155]

Yes I'm suprised more grows do not incorparate this in thier cab, I still can't see the light from the tip to base of the bulb reaching 3 feet? side to side would be about 3 feet. I tossed a 150 in just to compansate for the extra foot in the c22.

 

[Maj.PotHead]

untill i can upgrade to a 600w remote ballast i must work with what i have then i'll hang it bulb facing in when doors open for cab inspection. heres my cab just need to place in the closet hang doors light proof and test run it a day
there will be 10 girls 2gal grow bags over stuffed kinda he he, i'll have about 3 inch around each bag for good cab air circulation. when i do upgrade to a 600w remote i'll upgrade my exhaust fan also

 

[bostrom155]

Good luck Major, I'll check that out, nice scrog , what strain you running?
