Inside Out Trees, Silo Op, custom RDWC, water cooled

I use 5k btu per 1k of lighting as a general rule of thumb when deciding on an a/c. That accounts for the light itself ,and the other room equipment

Okay, so if 5k BTu x 8 = 40k BTu

4 Tons = 12k BTu x 4 = 48k BTu

Got a safety margin built in twice, desirable to ensure I can deal with high RH in the space.

In other words, one Ton per two lights, with safety can be seen as a good rule of thumb.

Rule of thumb for bare bulbs has always been 4000 btu`s of cooling for 4000 btu`s of heatgain from each 1K , but DBro`s dead on about extra equipment requiring the "overkill" buffer zone of the extra 1000 btu`s...especially running sealed rooms with CO2 supplements.....

I never needed the extra cooling using air exchange twice per minute with lung rooms , but dehueys and CO2 burners plus ballasts inside grow areas will require the increased cooling for insurance....and yeah , 40K should be more than sufficient for cooling capacity TTYS , but be cautious of going too overboard.....

Maybe 48000/4 tons won`t be a problem cycling on and off for 32K in bare bulb heat plus the extra equipment coverage , but didn`t I read where you were running swamp coolers or something of the sort ?......anyways...

Good luck and keep us updated....

Peace....DHF....:ying:....

Might even learn something if I'm not careful. :laughing:

Just spent a couple hours trying to pay attention to what you are doing.

Okay, so a little more discussion about my plans should help answer some of your questions and eliminate a lot of variables.

Equipment;
- 8 x Gavita 1kW Proline DE, these actually run at 1150W/98%, so call it 1200W, total 9600 Watts.
- CO² by tank, so this contributes no heat
- 4 Ton Water Cooled Air Handler
- Various pumps and fans

Of course the WCAH needs a chiller servicing it, that's covered. The room is on the small side and I'll pack it ridiculously full of plant material, which is the source of my concern about removing sufficient moisture to effectively control RH. Hence, my desire for a plenty big air handler to do it with no doubts.

Brought my popcorn.

I learn a lot every day. Sometimes the lesson is free, other times tuition is expensive. Wisdom is seeing the tuition payment soon enough to avoid having to make it, lol. Please feel free to ask questions.

Yes forgot to mention my rule of thumb is for a sealed room, no intake or exhaust.

That's what we are discussing; no air in or out. I'm considering the occasional use of an ozone generator late in bloom to help reduce the chances of mold, etc. Does anyone have any input on this?

Fuckin nice shots! Whats the bud in the middle? Hey I saw you posted on some other forum about using Gavita lights in a vertical arrangement. I was wondering if you ever found out if it could be done. I am pretty sure it is not recomended for the double end lights but I have the 600 PRO with the bulb mounted to the ballast. I was wondering if I could take it apart and alter it so the bulb would hang vert. As I am conVERTed to vertical growing!

In your shoes I would very much want to do it as a remote ballast with a fifteen foot lamp and vertical socket cordset, as indeed I already do. I dislike the idea of hanging a ballast in the middle of a bunch of plants where it will get dirty and hot. No good for either ballast or plants, best to at least mount the unit to the wall or ceiling away from plants, if you can't get it out of the room altogether.

I did not discover an awful lot about hanging Gavita bulbs vertically, apparently they're not even thrilled with the 600w bulbs being used vert, in spite of the specification sheet clearly saying 'universal mount' for installed orientation.

They're very much against the DE being used vertically, as it seems to cause the bulb to run at a different temperature, which hurts performance. Personally, I think that issue can be overcome, as can shading by the frame that carries power to the opposite end of the bulb.

Thank you for the 'kind' words, the above left close-up is Purple Jones, Purple Kush x Casey Jones. Straight between the eyes knockout punch couchlock naptime. The one to its right is a recent Cannabis Cup winning strain if I recall correctly, Super Lemon Haze. Very much the sativa high, but grows in monster chunks!

Ttystikk, I like your style. Probably because you seem similar to me :) I love to think outside the box and figure out new ways to do the old shit better. I am absolutely kicking myself for starting this grow as a horizontal scrog. The vertical section I got up seems way more efficient and way easier to maintain. Only problem I got with the no reflector is that it is a total bitch to work in my room. I got a hat with the brim pulled down low and the darkest shades I own but I still gotta be careful to divert my eyes from the bulb. I am gonna rig up some kinda temporary shade I can put on when I go in to work.

On the subject of tinkering, I am really into the idea of doing a Yo-Yo light mover for my lights but I don't want to buy the stupid light track. I saw your bike picture and was intrigued. Do you have any more info on it? Or some better idea for DIY light mover. When I was a kid I was growing using 2 arm and 3 arm suncircles but they are non existent these days.

You mean, this old thing? LOL

Yep, you and I do think alike, and I don't want to use a Light Rail either. No offense to those who do, I'm just investigating another option, trying to take advantage of my own personal lighting theory.

The best thing I've been able to think up thus far is to use the bicycle thing again, only this time mounted on the floor with the crank rotating in a vertical plane. Turn the crank slowly, use pulleys and string to multiply distance traveled and transfer movement to vertical fixtures inside the silo.

That's on the right track, I was just going to use the bicycle crank for the rotating part, with the motor driving it at the centerline.

I can hang pulleys and counterweights on the other side to balance mass and load, allowing the system to run smoothly as lines carry the movement to each fixture in the room.

In the simple design just make the yoke half the travel distance and flexible cable with a center eyelet just below the bottom stroke of yoke to guide the cable in the linear direction. Add pulley system to have a smaller yoke to crank.

Check out old manufacturing plants that was running all the machines on a belt and pulley system if you are looking for 1 motor 1 room. Or prove on one silo first. I'd say one per light to save on complications.

Only problem with that design is if the yoke is half the travel distance, then for a 4' travel the yoke would be 2' on center which would also consume 4' of ceiling space. I guess I could set it off to the side and use cables and eyelets to position the light where I wanted it. Do you know of some way to increase the vertical travel without such a large contraption?
