what do you use to cool the rooms? what do you keep the temps at during lights on and lights off? why don't you run a sealed room?

 

[mysticls]

Shortly after I moved to a place with more space and was going with 5 bulbs. My best was 13 lbs, nothing to brag about in that time frame. A friend who's idea originally for us to do the prototype 3 shelf did hit a walloping 16 lbs off of 4 bulbs but he started taking plants at 8 weeks a few at a time and was done in 10. They just kept putting on weight as the light and space increased.

so are you saying you got 13 lb off of 5000 watts? and your buddy.. 16 lbs off 4000 watts?? you start taking plants out at 8 weeks and than more at 9 weeks and than by week 10 you took all of them out??

looking good mf, hope you dont get to many seeds in their, you could always sell em, lol.
forgot to ask befor, you mention you split your lights via a relay so you use the ballast for both rooms, hows this done?
how do you wire up the 4 ballast to all 8 lights? i fort about doing this with my cage set-up but couldnt work out how to set it up, does the relay switch the ballast betwen lights automaticaly?.....cheers....mrc

The relay switches split into 2 lamp wires running into two separate rooms. The switches are controlled by a timer which simply switches the power to the other bulb in the other room. Ballast runs 24h.

I move lots of cfm's when it's hot and have a good source of outside air. Usually everything stays in optimal range with occasional hot days during a heat wave.

I set my thermo at 80 in the hottest part of the room. Lights off the rooms are between 60 and 70 depending on weather. I add heat in the winter.

I'm in a tight space in the one place with very little insulation. I may cool my air in with a air conditioner in Aug. We will see how it goes.

I don't seal my rooms because sometimes the doorway is the air way for passive intake plus I have a large fan in the doorway for air circulation. There is very little room for equipment in those dimensions. The name of the game is keeping everything close to the lights. People I know have tried their own variations of my system and when they make the rooms a little wider the buds are softer with plants stretching. I always tell people you have to keep it narrow.

Remember that this was a different variation of this set up. We did 3 shelves with plants that were vegged for 4 weeks plus it was a single room. You get smaller crops by doing 5 shelves/ 10 day veg but at the end of the year you may be able to pull off 2 extra crops which not only gives you a higher annual pay day but a more frequent pay day. Doing relays really increases your annual but the hydro bill increases almost double too.

As far as the 16 off of 4 bulbs, they took a few plants down every day for 2 weeks after work and in the end they had 16 lbs. Pot was marketed a lot wetter then so I'd imagine by today's standards of 20% moisture that would be maybe 14ish.

man that is heavy duty set you have there NFarmer...
Im a PBP Botanicare grower in DWC..also did some in a few Soil rigs while back..But maybe you had a bad bottle to.If it smells off I usually take it back as Ive had bad bottles of a few Botanicares products as they are mostly organics and may not of been stored correctly..I'd bet that or you used a bit to much as LK has a bit in it no matter what the Label reads..I use it only as a micro nute to my macros..
Anyway I'd do the same and drop it if you guys both had the same reaction caue thats to much work to loose cause of bleedin herms..Keep doin it tho..great Stadium rig man..props x2

Thanks man.

It seems to have backed off as far as the hermies and new seeds go. Looks I'll do alright. Things are shaping up pretty good except for a bit of burn from my well water.

sound mate, good news bout the hermies then! is it just a few plants that turned then not the whole crop?

do you have a pic of the relay you got? or what name/spec it is? sorry to be a pain its just iv wanted to do this for yrs now, get 2 of my cage systems running using only 4 ballasts but im no sparky, i can do almost anything once iv seen one set-up but not knowing the correct name/terms for things it gets a bit complicated when asking for what you need in the electrical shop! lol
like i said ill be fine once i know what i need, i wired up my grow room with full control panle direct from the mains so wiring up is no probs i just need to know what parts to purchase.....nice one mate....mrc

p.s sorry for the hijack! lol

Well, I'll say it. I've been going over and over this thread and just plain love it. Wish i would have thought about this idea or saw it. When i had my large wall in closet. I could have doubted my yield over running a pair of Ebb&Flo tables. Now I think about it and what a waste of space. You can bet, I will be trying this setup this winter. Got some nice plans for this setup with a couple of changes and my Green Giant keepers. Going to be some little green monsters this winter. Thanks again for sharing your grow and setup with us Northern Farmer. Great idea and setup.
Take care,
BG

 

[mysticls]

GD, whatever changes you have in mind either drop me a PM or post them in the thread. Very curious what your thinking because I am setting up something similiar so any new ideas wouldn't be a bad idea ; )

No worries, I'll make sure to post my changes and also do a thread as well. I'm a hydro person and don't mind soil. I just like the cleaner area minus soil. I'm think the same setup, but some trays in a Ebb&Flo Hybrid type style. I'm thinking some square pots 7.5" x 7.5" x 8.75. That is equivalent to a 1.5 gallon container. This will allow for a nice root mass and some good bud formation also. I'll do some trays and make the top tray fill and water fall down to all the lower trays. Let the system run for so many minutes and then turn off. The water will cascade down to each pot feeding each square container. That the only changes i'm going to try for the hydro. For the lights, I'm thinking some cool tubes "maybe". Haven't made up my mind just yet. I do know, all lights will be 600HPS 240volts ballast for sure. This biggest change is Hydro over soil. Just my thoughts on the type of grow.

Really love this thread and i'm great full for the idea. Thanks for sharing.
Take care,
BG

Edit: Will use the 8" Slab Tray by American Agritech to house the square posts. I think these units are 3'5" long.

hey Northern Farmer I have a friend who has a 5' x 5' room with 7' ceiling. He has two 1K HPS lamps laying around too. Do you think he could pull a 2 bulb stadium in that space or is it just to narrow (6' 5" wide on yours - right?)

thanks

-suga

 

[mysticls]

Suga.. he said the closer the better. The farther away they are the more strech he gets so he always tells people to make them as close as possible. With only 2k watts it sounds like 5 ' wide would be enough, you just might not be able to do 5 rows on each side

and yes his is 6'5" wide on this stadium setup

 

[sugabear_II]

Thanks mysticls - I know he said not to go any wider than 6' 5" but I'm a little concerned that going less than that could put the plants too close to the lamp - but like you said it would just mean less rows. Mayb 4 on each side instead?

anyways thanks for your input - hopefully Northern Farmer has some experience to share as well.

 

[guest123]

This looks to be the way I'm going once I get setup indoors.

 

[Guest]

Mr Cheese,

do you have a pic of the relay you got? or what name/spec it is?

The brand I use is Allen-Bradley

I'm not sure which is the part number, there a few....

LIST 367G
37547
0045

????, hope that helps.

GoldDustWoman,

I tell anyone who plans to try this on a hydro set up to make sure they are able to turn their plants once a week in their system or else you have week sided plants and serious leaner's. You will have to tie back plants near the end anyways. Pics to follow later of what I mean.

Sugarbear,

I don't know about 5' wide and 1000w. That is too narrow IMO. I know you couldn't do 5 shelves with those dimensions anyways because the rise would be too steep and tops would block bottoms = fluff.

He could try less shelves, 3 or 4 and 600w maybe. Otherwise I see it getting too hot unless he can install air conditioning or cool tubes etc...

Humidity would be an issue unless he had a very good exchange.

I didn't realize their would be so much interest in this set up. I may ask for this thread to be moved to the Grow Room Designs topic. I will also do a list of things that people have to seriously consider before they commit to this design. There is a fair bit of work involved like leaf plucking, plants turning etc but can be very rewarding if done properly.

The design may have issues in hotter climates if the proper precautions are not taken. We are experiencing near 100 heat right now and I had a couple of leaner's toast up a little while I was gone. Came home from fishing to over 90 heat and am waiting on blower upgrades. First run in this house and geographical location.

You never know what you can get in a cycle here. The crop started off with me having to add heat because it was around freezing temps at night to near 100 in the day 7 weeks later. Next run will be the other way round with near freezing at night to finish.

thats exactly my problem.. temps here are 90++ during the day and 80s at night. I am debating wether I should do a sealed environment or non sealed.. if i did a sealed envionment than I would have to stuff a portable AC in each room and the portable AC don't work too well..esp with 4k watts of lighting.

either way I have a 12 inch vortex fan that does 1140 cfm for each room so I know ventilation won't be a problem...

what do you recommend for setups that exceed 90+ degree outside during day and 80 at night??

also look forward to your list of things needed to be considered before going this route.. hopefully its in the next few days because I am proceeding with this as we speak...

 

[Guest]

Hey Northern Farmer,

Thanks for the advice. I plan on turning plants as needed and also shaving their lower legs as well. I thought about what you said and ran into this problem before with other grows. I use "Screw Eye Hooks" in the walls and tie off the hook the the main stem. If the plant tries to lean. The string is already some what tight and there is no slack for them to lean any. Thanks for reminding me about that. I had issues with a monster NYCD pheno i found in some F2 seeds BOG sent me. Yes, BOG did some F2's as gifts for some members and they where awesome. The pheno i had was a 3-4 oz dry weight yield per a plant. Very top heavy and a problem. I think the trays with square pots will help also. Thanks for your help and sharing your thread. I'll make sure to link you when i get going this early winter. Love the thread and keep the updates coming.
Thanks,
BG

Also went on http://www.ab.com/ which is Allen-Bradley website and put in those model #'s and came up with nothing... could you go on the website and find the product and give a direct link or possibly give more info about the relays... these relays will save me about $1200 in 4 ballast so i think its def a wise investment =)

Wow...stuff is expensive there. I pay about $100 per but always have the hardware laying around to add (wire, mogul, plug...)

I will take a look. I will also take a pic of the unit.

Some guys I know actually do a small room for AC and pump the cold air out of it and exhaust the hot air the units produce. They actually split the small room in 2. Cold air to the gro from one and hot air from the AC outside.
