HP Stadium

[jakeh]

for all you guys doing stadiums, do you have any pics of your original frame? buddies putting one together, he was just going to use a shipping container as a frame, but that fell through cause he cant get it in his shop and now he wants to frame one out of wood but he aint no carpenter and could use some help

It's all right here in the thread. Check out post #42.

let me guess, you in the wack or langley??? if not, fuckin great production, if you can, modify the caps on your ballasts to the next bigger size, you'll get like 1500w of light, but have to change yer bulbs every 1-2 crops

 

[medicine_man_bc]

i'm also guessing that those are 2 tralers yer rockin nice work. this my my own med grow, stadium lighting all the way

 

[v321]

has anyone ever thought of having the middle bulb horizontal (bare bulb)? I mean I noticed vert bulbs dont shine much light under it, I see really weak growth with plants on first tier and plants on the floor.

 

[Grizz]

the verts will work best, you have to build your stadium low enough to floor that you can lower your lights so bottom tier gets good light and still have good light to the top tier, shelf spacing is critical for good light to all plants, and obviously smaller or shorter plants do better in the stadium

 

[Mr. Stinky]

just wanted to bump this thread....its a good one, and everyone should see it. heres one that may or may not be affilliated with me you'll have to excuse the hundred or so dead flies from takin the lights apart to re-wire. 11'6"L, 7'W, 6'9"H

Wonkanobe,

Yes I've read it. Good book. I lent it to a friend and the police took it when he was paid a visit one afternoon.

Chaingmai,

We just hang the MH's down the middle evenly spaced out. We have one fan at the top of the doorway/enterance of the chamber and then the blower for air out at the other end. It creates a wind tunnel that cools the bulbs. Outside the chambers we bring in outside air. It is drawn into the chambers by the exhaust.

Best we've done with this system to date is 7.5 lbs with 4 bulbs using 6.5'x10' of floor space with a 6.5' ceiling.

We usually run 2 of these rooms side by side though (double that 7.5 lbs) using relay switches to split 24 h light into the rooms 12/12 hrs. A small bedroom can really yield this way and it's the most efficient way to run your ballasts because they are always running at maximum output. When you turn a cold ballast on normally they take a while to run at top output and tend to draw more hydro to get there.

Who knows where to get these light relays? Can I get a plan of you set up? Going verticle!

Scematic please!

Scematic please!

Might be hard to explain it all.

The wires you see I just cut instead of removing the screws. Those go to your timer. You can piggy back as many relays as you want to the timer.

Basically you have 2 screws for your lamp wire off the ballast. Then you have 2 sets of 2 screws that are the split. You connect each lamp's wire from each room to these. When the timer flips the relays switch to the other lamp.

There are 2 screws for your timer and you piggy back your timer wires to the switches. It is a separate power source for the timer.

I don't have photo shop or I would do up a crude schematic for you.

Please help me out! I need this!

There's no link for where I found this idea. It was a tip years ago....

About 11 years ago I talked to a friend who was a commercial grower. He said he was trying the relays out. I struggled to understand like you. His locations were off limits understandably. He made it work and swore up and down. He picked these up from an electrical supplier he was in with. He knew people who would wheel tables and do a room switch to accomplish the same trick years ago he said. He knew a thing or 2 about electronic equip and thought about switches instead.

Later an opportunity came for me to design a big show for somebody. They wanted to try this stadium out with 5 instead of 3 shelves( we used 3 shelves up til then) and no veg. Just out of the tray and into flower. I tossed out the idea of splitting the ballasts and having 2 rooms. They bit and the rest is history.

I used my usual shop to order these in. I was the first one to do so. They now sell literally thousands a year now. He gives me credit for being the pioneer but it's not so. I'm just the first one he knows who tried it.



1 ballast-1 relay-2 bulbs

4 ballasts would be 4 relays and 8 bulbs. Each ballast is split to 2 bulbs which are on 12 hours each.

You use 1 timer to coordinate all the relays to switch at once.

I will take another picture of a piece of equipment that is used as a switch box and explain later. I have a few updates I'm suppose to do on this thread. I'm behind...

I need help here anyone links to relays & wwireing diagrams

one more thing, where do you get the 1000 watt cmh? i can't find it over 400?

 

[solarz]

^^i believe 400w is all you can get for the CMH.

Thank you Bostrom. good link...

 

[bostrom155]

No problem. that's been circulating around for a bit. good luck

 

[shuswap]

northern gardener can u comment on how u like the purple kusk? we are finding it to yield low and be very finiky to feed,wondering if u had any suggestions as the price is right for her! thanxs

Afteer reading the threads about flip flops i think it is better to buy another $70 ballst & I wire it.

 

[Lugen]

I'm waiting for an answer on what's better:
5 shelves, and 1 gallon pots

or

4 shelves, and 2 gallon pots

 

[Mr. Stinky]

i do 3 wide shelves with 3 1/2 gallonbags, 2 girls each, with 3-4 weeks good veg time.
