New 12'x24' Grow room

[Satans pal]

We might end up making this just a flower room. What do you think?


I have used this shed as a storage unit for the past 5 yrs, and now that I am a med user and can be a provider, I am turning it into a grow room. We are replacing the roof, going to wire for 220v and 110v off a sub panel that will be wired from the house.

It will have a 16'x12' flower room and a 8' 12 veg room. I plan on using 6 1000w hps in air cooled 25"x25" sun system hoods for flower and 4 1000w mh in the same kind of hoods for veg. there will also be fluorescent supplemental as well. I was originally going to recess the hoods into the ceiling but upon trying to see how they would fit, the space is too small. I am now going to remove the cross pieces and drywall it like a vaulted ceiling then just hang the lights with the ducting exposed. I have 2 vortex 8" fans, one for each room, that will sit on top of carbon filters, and push through the hoods, probably to the back of the shed on the back wall. I had originally planned to use roof vents, and just vent in the "attic" space.

Any thoughts on a different way to vent the rooms would be greatly appreciated.

I will also be installing an a/c unit and a wall heater in each room to regulate temps. There will be 4 wall fans in each room for air circulation as well. I also have a stand up humidifier for the veg room.

Will be trying to do an 8 bucket system for flower, not sure to go with the hydrofarm drip system or the ebb n flow system. Once again any thoughts or opinions appreciated.

Will have an ez clone 60 and then go into a 18 site rainforest before going into buckets.

I have been in soil for awhile and just now started messing around with hydro. So all opinions are welcome.

I will be continuing to update on this thread, and then when I start the grow I will move to the hydro section.

I will be starting with DJ Shorts True Blueberry.

Thanks again for help and support, its good to be back

This is just my opinion.

#1 - You need more fans for ventilation. I don't think an 8" running through six hoods and a carbon filter is going to cut it. An 8" each sounds better (hoods/filter).

#2 - Suck through your hoods, don't push.

#3 - Have you explored vertical? Stadium style with bare bulbs running down the middle is nice.

#4 - Ebb and Flow is toilet flush simple, dippers are great if you maintain them.

#5 - If you are not already running the EZ-Cloner 60 and are rooting everything successfully, then stick to your tried and true method. Take this form a guy who owns a 120. I just bought 400 rapid rooters because I can always count on them.

 

[Satans pal]

Just curious, but why is sucking better than pushing?

and are you saying a 8" fan per 3 hoods? or one per hood?

I have seen the stadium style setups, but I am limited to 30 plants total.

do you have experience with ebb or drip

and yes I have used the ez numerous times with great success

Thanks for the info, SP

I am currently using the ebb n gorw ebb n flow system lol... i to am a soil fan but this shit is impressive to say the least, massive growth. I think u can run a few more plants tho in that big of a room, just a thought. In terms of venting why not seal the room if you have a ac unit. I have 6k seale with a 25btuac it works nicely, tank co2,just a thought. Nice stran choice, gl in your growing.

 

[MHHSP]

Yes pull air do not push it, do some research or trials and you will find its much more efficient this way. If you have an ac unit your 2 fans should be fine.

 

[Satans pal]

So, we are starting on the walls today. Front, back and divider.

Goo I have heard about sealed rooms but have not had the time to see what they are all
about. From what I understand they have no intake and vent? Would be curious to see how that works. And if it has to be a total seal, then I dont think I could pull it off with
my shed. Thanks on the strain, looking forward to trying it. Are you using the buckets or tables?


MHHSP I have always found that the airflow from behind the fan is a lot less then from in front of the fan. So I thought pulling through the scrubber then pushing through the fans would be better.



Thanks for the replys and keep em coming

Insulate the fuck out of the walls and roof, every dollar spent on insulation and vapor barrier will come back many times over in reduced cooling costs and heartache without it it will rain inside in the winter and be 110 degrees in the summer

 

[Satans pal]

Oh ya, it will be fully insulated. Hadn't thought about the vapor barrier over the insulation before drywall though. Trying to coordinate with the electrician to wire everything up in the next couple of days. Thanks for the tip.

 

[growshopfrank]

Another thing have you thought about using something like 3/8" plywood instead of drywall its so much easier to screw/bolt things to. on my current room for electrical i used armored cable and ran it all on the surface boxes and all and I'm very happy with the results if I need to change change anything its a snap because everything is out in the open.

 

[Satans pal]

What did you end up doing for the seams? That is an awesome idea, thanks.

So I am now talking with my partners more about turning this into one big flower room since I have access to clones elsewhere. That way I can still stay under my limit but have more production.

What do you guys think, if it was you room how would you do it?

 

[ImaginaryFriend]

I would consider re-installing the horizontal members you removed... they look structural to me (prevent the spreading of your walls and roof).

I don't have a problem with you pushing air through the lights. Pulling is more efficient in moving air volume through a system, but not necessarily more efficient in cooling a lamp.

Pulling creates pathways that avoid resistance. Pushing forces air into those points of resistance, and creates turbulence.

Turbulent air, it could be argued, presents more air against hot things, and therefore might be able to remove more heat.

Additionally, it creates positive pressure in your ducting so any imperfections in your run push clean air back into the garden, rather the pulling unfiltered air out.

Some hood companies have recommended pushing over pulling based on their tests. I should link to a source for this claim. Maybe I'll find one in a minute or two. In the mean time, feel free to disbelieve. My snack is burning on the stove right now.

And after all that: I pull to vent. But that has less to do with theory than it does to build out geometry.

Seems like 6k flowering with 4k veg is a little off. I would suggest a bit more flowering light and a little less veg light. I go 1.2k flowering 400w veg myself.

 

[Satans pal]

No no, very well explained. Totally makes sense now.

I will definitely be pulling.

As far as the cross pieces go, once the walls go up it should be solid. If we think not then we will add more. The reason they were removed is, the hoods I will be using are 25"x25" with 8" vents on both sides. Originally wanted to recess them between them but they are to big. Plus the ceiling would have been only 6' and now I have more room to do stuff.

Thanks again

 

[Satans pal]

Compost I think we will be going full flower room, So does 10k sound good for 12'x24' and how many buckets do you think I can get in there?

 

[Gooey]

I like the flower thought, i say 4 buckets per light...i have the buckets, they get huge its crazy...sealing it is possible, not as tought as it seems...just have to use alot of tape lol...ne ways gl to you, i think you can run more lights 48 plants seems right to me with that system...peace

 

[Satans pal]

Hey Goo, it seems to me that that would be too many for the space since I want to do trees, 5' tall x 3' sq ft wide. I figure about 24, plus I gotta have the res and every thing else in there too. My problems right now are where to draw intake from and where to vent at. Any ideas?

Also, how many scrubbers do you think. Placement of fans, scrubbers and the rest? Thanks, SP

 

[Gooey]

Ahh yeah if your going that big then i agree...one can fan combo should suffice, get a big one with a 8" fan, maybe put the res at the entrance on either side...i think you can just run a fan pulling thru the lights make a y at the end...gl

 

[compost]

10k over 12X24 is pretty good because you are gonna lose some space on the sides for up keeping the room. I don't want to get into the buckets to much because my experience is limited with hydro except flood and drain. Now with 10k in lights I would suggest making sure you have a very good dehumifier and more AC than you anticipate needing.

Since your medical I would suggest going reverse nature on your lighting. Run the lights at night to keep temps down and lower your energy bill. Depending on your sun exposure some nice shade trees might not be a bad idea.

If you have a reliable source for GOOD clones a flower only setup is nice because otherwise you have to turn your moms over quickly as they tend to go into flower regardless of light cycle when in close proximity to a bunch of their sisters that are in flower.

what???where did you get that thought from?
