inside dimensions of the room.
Great, thanks Mr. Stinky,inside dimensions of the room.
Depends on a few things.
If you use the full 10 feet you can squish 220 in there so 55 per bulb max(providing you use the 1 gal grow bags I do). I like to pack em tight then once they stop stretching take out 20 of the weakest ones. So you double that and you need between 400 and 440 if you are doing a flip flop system like I do.(2 rooms, 4 ballasts on relays, 8 bulbs)
I'm going to post pics of one I'm setting up right now in the morning. Bed time.
Thanks for your reply NFR you have been very helpfull with sharing your knowledge.
I have some more questions?When you veg how many days are they and how tall are they before going into flower?What strength Fertilizers you use for Veg? and for Flower?How many times you feed in Veg?How many times you feed in flower?Are you still using Peters ferts?
Thanks again
It's a newer brand of Hydroponic food on the market up here in Canada.
Pro Mix has a lot of peet which brings the PH down. 6.4 is not high for soilless mix, for hydroponics yes.
Here's a pic of a undetermined Kush strain at one week veg.
They are much bigger than that now. Had to do some thinning today. Big fans had to go.
Long time listener, first time caller. Firstly, I want to thankyou for your help and willingness to "spread the wealth".
I think we all have enough info to recreate this masterpiece in our own ways. I do have a few questions if you don't mind.
How do you cuts end up so big after one week of veg. From the picture their huge. It looks like you take only tops and leave several nodes with no trim. Is this to cut down veg time?
Also, how do you flip two rooms during veg with 18/6 cycles, 8 bulbs, 4 ballast. I recall you working on vegging in ther areas at some point.
I simply cannot thank you enough for your ongoing helpful input and detailed responses NFR... your attention to detail hasn't been overlooked, and the contribution you've made to icmag and countless people's lives is beyond measure. I think post #507 sums it up...
Compliments aside, here's my small contribution to your work; hopefully it helps others as much as you've helped me.... cheers, boss. LBPULLERS

42 - Start here first for setup of shelves, layout: SHELVES NEED TO HOLD TOP-HEAVY PLANTS in place. Add 6" walls to each shelf is a good idea or tilting and slightly overlapping the shelves so shelf above holds top of pot below (posts #289, 296)
25 - 6.5'x10'x6.5 statistics on performance, light cooling ideas, layout desc
29 - LOTS o LEAF REMOVAL, nutes used in other grows, watering regimen
32 - MH lighting ONLY in beginning; cooler temps? Later NFR switched to Eye hortilux 1000w hps
608 - food/water/food/water/food/water never exceeds 900pm per feeding
35- thoughts on evolution and efficiency uses 1g bags with promix -or- allmix, GH and other nutes
37 - rotate plants 180deg weekly to minimize leaning
38 - "Once you've seen vertical lighting setup up properly you will never use a hood again, I assure you.." My old 100 box comes to mind...
41 - 55 plants per light?
55 - training and pruning are what set the pro's apart from the novices
56 - 1g promix, no run off. lights start at middle shelf, raise with stretch
61 - ph 6.4 b/c of peat in promix... removes large fan leaves from kush, thinning
76 - 200 plants = 25g h20 every other day
78 - sometimes uses co2, depends on location and season
84 - top shelf is 22" from ceiling, all others 10" down from shelf above, sitting on 8" boards
92 - peters 10-30-20 indoor & 20-20-20 for outdoor... wow! used that back in college. full circle?
112 - Ventilation details (1000 cfm exhaust min) , Peters fert mixing rate, elect consumption,
116 - odor control is not an issue for him
123 - expanding the room to accommodate more plants or vent loses yield. KEEP ROOM NARROW (6.5'), also discusses veg time correlation to yield and annual return
135 - Room width discussed, shelf spacing, always rotate plants weekly, thoughts on pros and cons of this setup, effects of temps (90 outside is trouble for him)
139 - AC in second room passively drawn in while heat is vented out second room, cool is drawn into grown from second area, heat exhausted
153 - History of design and relay idea origin
160- water running out of bottom of the bags would indicate overwatering for his regimen. Enough for two days is all that is applied, and only to those who need it most.
191 - Discusses PK, easy to use in his design b/c of no stretch
206 - efficiency of system comes from overlapping light.
209 - hanging PVC from ceiling allows under access, auto watering. Design discussion
240 - Dirt outperforms hydro consistently in this method. Higher plant density due to slower growth: 200 plants per 425 cu ft is alot!
246 - Shelf spacing: 22" from ceiling, 6" run, 10" rise thereafter. Floor irrelevant?
252 - shorter plants on top shelves, stretchers on lower shelves
273 - PK veg for 12-14 days from root, nets 6" plants into flower
286 - Plants under light can be very close, as heat rises from bulb. Excellent light distance discussion
306 - **must read** Overview, reinforces why his system works
308 - Shelf material idea; metal "track" for steel headers/footers?
309 - Aluminum roofing for shelves? 1'x10' = $25
339 - reinforces light overlapping is key by showing that a guy with a 4k setp that's just a foot smaller (9' instead of 10' long), holds nearly 40 fewer plants, and still yields almost 2lbs per light. Also, expansion area to accomodate filter and fan; gets the out of working aisle
349 - PK flowered at 6" finished at 18" SHORTEST ON TOP SHELF, 180 deg turn weekly
400 - The biggest mistake is flowering tall plants... 'its a fine line between too small and too tall'
471 - LIGHT MOVER discussed, USE PIPE TO HOLD BULBS VERTICAL
472 - Well executed knockoff room. Super clean 12' long 5kw digital ballasts
473 - BOTTOM SHELVES NEED LONG TRAVEL to allow for undercutting above shelves, which allows taller plants (possibly mixing strains in stadium)
483 - NFT tubes discussed. Tubes hung on chains from ceiling allow access, net pot can't be turned w/o damaging roots tho...http://www.stonerforums.com/lounge/growfaq/1449.html
490 - Plant count reduction discussed by author of #472 BWD
491 - suggests recycled 2l bottles as pots
493 - return of NFR, BUD PORN: photo #2 shows relocated exhaust/filter, switched to FOUR SHELVES, 2g bags, removed poly wrap walls. Still running PK after two years
498 - Long term update from another grower with details about coco with drippers
502 - see 493
507 - Another grower chimes in about his exp with stadium. Best props I've ever read... NFT should be proud.
509 - Building drain shelves with pond liner and 3/4 plywood
530 - Build your own relay setup! Excellent tutorial...
http://www.hydroponics.net/learn/grow-light-controller.asp
546 - NFR says he is going back to larger, longer vegged plants on 3 shelves
547 - Tops his PK for 2-3 tops, increases yield
549 - If it's not a bushy plant and you can keep up with clone supply and TRIMMING (uh-oh), go with one gal 5 shelves. If it is a big branchier plant, then go bigger pot and less shelves
560 - Light spacing is 20" from ends and 22" to next bulb center
563 - lights are usually level with the third shelf (middle of room vertically)
565/570 - moved fan above room, ditched poly walls, squeezes a bit more in where fan was
591 - 600w = 5' wide room. 3 shelf is a long veg time...he's gone to 6 shelves, rw slabs to simplify and reduce veg time
*try building your shelves out of plastic gutter or composite deck planks. No mold issues
