how many plants will my setup flower

[MRovergrow]

i currently have a 5foot by 5 foot floor plan with an 8foot hight in a walk in closet. theres a huge 2foot by 3 foot home made air cooled 400watt hps in the center with many side lights. i run 4 2foot floro tubes on the dimest lit wall spaced evenly every 1 foot, and 4 four foot floro tubes on eather side of the hps hood. a total of 520 watts. 400hps. i have many more lights to add if need be but i would like to cover every ince of floor space with plants 3 feet tall before i flower. how many plants can i cram into my space? im guessing 100 give or take if i use many long and thin pots on risers combined with 1-5gal's. painted water bottles with cut off tops, and strait sides make great pots and 16 fit into a sq foot. 16X25=400plants?

You are going to veg 100 plants to 3 feet and THEN flower ????? And do all this on a 5'x5' footprint ??? Tell me you are not serious........this is just a chain yankin post.......

If you are going to flower plants at 3 feet in height you need enough HPS lights to illuminate a Super Wal Mart parking lot. I'd poke around in the FAQ's for 3 or so months, then I'd worry about growing.

i have growen and flowered over 100 plants in my day. indoor and out door. from merical grow mishaps to promix. currently growing 8 plants under 520watts and im having no problems at all. tallest plant is about 3 foot from bottom of pot, begging to go into a 20-30gallon pot. im using pure farfard soils with an extreamly light 6month slow release fert. i know they are to be avoided but this one is premixed and comes with lime and phed to 7. after about a month i start using alaskin fish emultion 5-1-1- petters 4-16-8 strong start, superthrive, and rooting hormon depending on the plants needs/nut probs. seen em all and a combo of the above listed can clear up almost n e thing.

They'll be rootbound long before 3 ft. esp. in such lil containers .
Do a lil more research , and how about some pics of the enviroment you have for them , we might be able to help a lil more w/ more than just a mental pic.

100 in a 5 x 5 will never happen , muchless that large . Usually as a rule you need 1 gal. of room in a pot per 1 foot of vert. plant desired .

i understand all rules and laws that go with growing pot, and i have 25 one gallon pots but i want to really blow the top off this grow with insain yield numbers. the idea behind my madness is maxamise root systems=maxamise buds. no matter the end numbers i will use pots way to large for my plants and lst or top to mantain an even canopy. sry about pic's i have many from past grows in c22's and what not but i cant seem to find my digital cam, maby i can make do with a scanned poloride just to give a good idea of what im working with. i have a huge potential for massive plants with towering colas totaly surrounding my hood in the past i have pulled a half p dry from one plant scroged under a 4by2foot screan and 150watt hps. with nothing more than a 5gallon shallow pot, i think the overall hight wasent over 2.5feet, with 50 budsites all exactly the same hight each swelling to 7g+. i added some pics of my last 150watt scrog i mentioned for refrence. the hood is my smaller hps currently out of service. replaced by a kit ballest i built using an old militart water proof ammo case for ballest box and an old extention cord. works great but it gets so hot i have to draw my intake from the case just to counter act the heat build up seeing as the balast transformer is the hotest thing in the room by far. 130F+

you can't flower bushes in a 5x5 with a 400hps, and expect maximum efficiency or anything even close, it simply doesn't have the power. try a SOG flowering clones at ~10 inches under a 1000hps or a couple of them in that small space, or 4 x 400hps in that space.

how the hell can i vent such massive lights, and will i blow my breaker with over 1000watt loads. i know the lower branchest will be way under lit givin 3 foot to 6 foot finishing hight but many many floresent toobs lineing the walls will counter act this making for 5 walls of light all directed inward or so i hope. atm escaping light is so intence from under the door it takes 3 blankets over the large window in the room just to hide it, im guessing the largest plant suffered light burns dew to being bent under the hood 2 inches, i was playing around with the closest my lights could go 2 the plants. as far as i can tell touching the hood is a nice 80F a mear 2 nches from the bulb. correct me if im wrong but is that not the closest distance possible with out heat damage. emagion 100s of budds all evenly spaced under such a hood. growth resembles outdoor results in the past as far as nod spacing.

snippy eh?

Well that's up to you... the greatest skills a grower can posess are patience, willingness to learn, and a healthy DIY problem-solving talent. I can tell you from firsthand experience that a 5x5 walk-in WILL accept 2000 watts of light WITHOUT use of cool tubes, no shit, and by staggering the ignition of the 2 lights, there will be no breakers popping (FUSES blow, btw), and with properly installed ductwork with an active intake AND exhaust, you can keep temps in the correct range.

But it seems that you are going to do it your way no matter what anyone tells you so why bother asking?

BTW I'd love to know how you pulled the half P under a 150... the half gram per watt of HID per month rule would have you at a little over 2 zs dry... :wtf: and almost no one actually hits that .5g/w/m mark!

[MRovergrow]

well to be honest i did line the sides with clfs so the combined wattage for the grow was a little over 220. 350grams means i was well under .5gpw. the stem structre was insain starting from 4 main stems weaved to cover a solid grid with a single growth site per 1inch square. total time start to finish was over 4months vedge alone. any tips on improving my current venting system welcom. via 4inch duct into roof with passive intake coming from the crack formed by the door when shut. as far as i can tell 95% of the air is drawen from the house as long as i shut my centrial ac off, keeping temps under 85F. more fans and more moving air maby?

[stinkyattic]

A half pound is 224 grams, and the formula only counts HID light, and only counts it in the flowering room... you can add a LITTLE for flouros but not much, I'll give ya 200watts.
With a 2 month flowering strain, this is your GOAL:
((0.5g/200w)/30d)
So you have 100g per month, and a 2 month strain, that gives you 200grams total, and that is actually considered a level attained by an experienced indoor grower with everything dialed in perfectly.
Anyway not to argue about that...
Your problem is that you don't have 'real' ventilation. A passive intake (=crack under door) can't handle the heat from HID lighting.
You're going to want another exhaust placed high up... oh fuck it, there's someone doing this exact space, here's a link to her log....

She's growin in the same size walk-in closet and has the capacity to flower ~ 50 plants finishing at ~1-2 feet each under 2000w total. The plants have to go in as 10 inch clones, rooted and then vegged for a couple weeks. She isn't finished getting her clone production up and running so the plants that are in there aren't quite the way they are eventually going to be, and she's only got one of the 1k HPS turned on atm.
