Thank you

This by far is the best thread I have came across on here. I have gone thru 66 pages and soak up much knowledge from your past several runs.
Since your moved to the NE. Can you please fill us in your current grow style as temperature is different. Do you still run high rf?
Also never seen any pic of your veg room, as veg is very important to build the foundation so I came to realized as you veg for 7-9 weeks.

More pix pls

Started two days ago and couldn't stop reading this badass thread!! I'm about to set up a 21'x11' room and was gonna go with 8 epaps or gavitas, but after seeing DJM's results I might just go with single ended bulbs with a parabolic reflector or maybe the sun system silver sun DE reflector. Decisions.... But I have a few questions

1. If I go with DE, would I need more intake fans since they heat up more than single ended bulbs? I guess that depends on environment and dialing in the space

2. DJM uses 1 fan in the winter and 3 in the summer, but how strong are these fans(cfm)?

3. Would it be easier just to get a can fan pro series in say 12" and have multiple ducting off one fan and use the speed dials depending on which season you are in? Winter low, summer high? Would this work or would it be better off using individual fans(1-3)?

4. How big of a filter would y'all recommend to use in a room that's my size for the passive exhaust? 21'x11'

I'm going shopping in a couple of weeks so hopefully DJM, waxi or somebody can chime in. Thanks guys!!

D2g, I'll be glad to chime in with my thoughts on your room conditioning...but a few questions would help us.

Where are you getting the supply air volume from(conditioned space in your home, or self contained & outside air)

Are you intending to install carbon filters ?(this will massively change static pressure in fans & sizing)

Are you planning on running 12 months a year, and what are your mean temps in a calendar year ?

I run all of my rooms 12 months a year, all self contained spaces, with no hvac equipment installed, my ambient temps here range from 0 deg F - 90 deg F. I shoot for an average of .75-1 air changes per minute, but I don't prescribe to the dew point growing method

I run separate controls for multiple fans, all multi-speed MaxFans...all of them are about 10x20 in sq. feet like yours. Allowing the controls to maintain accurate temps, while adjusting fan speeds based on temperate seasons works perfectly.

Went back to read this thread again and found some of my answered on post #48 and #181. On post #94 tho, he states that he turns on his exhaust at night. Isn't the exhaust just a filter hooked up to ducting that allows air to exit outside 24/7? I never ran a sealed room before, so do any of you guys know what controller he uses on his intakes that keeps his temps steady at 82?


Bwanabud,

I'm in CO and will be using conditioned air from within the house. Ambient temps fluctuate anywhere from 60's to 80's depending on how much I turn on/off the heat and AC in the house. Depending on what the season it is of course.

when i ran an intake i had the intake hooked to the "cooling" input on a autopilot greenhouse controller with the controllers sensor hanging at canopy height, with the controller dialed to whatever temp im trying to reach

when i ran intakes i also used 1 exhaust hooked to a carbon filter...sometimes this would be used as a passive exhaust with no fan and at other times it had a fan and was hooked to a timer set to come on at lights off and turn off when lights kick back on...and at one point i had 1 passive exhaust with no fan to dissipate the intake air as well as a second carbon filter hooked to a fan for night exhaust only...i ran this system in 7 different locations the past few years so things were always altered to one room or another

hope that helps

cant answer the DE question as im personally not a fan of them ,nor do i run any

i use to use 8 inch can fan or vortex fans for my intake , each one is roughly 700cfm i believe. depending on the room lay out, temp outside and inside temp that you are aiming for you may need larger fans or more of them

one 12 inch would work fine in the summer when you need more air movement. But during the winter a stronger fan can be a bad thing. Thats because the larger the fan is the less it will cycle on to cool the room and the less it cycles the more the RH in the room will build up. last winter when i was running a 8 inch vortex as my intake for a 16kw , 12 x 40 foot room, the intake would kick on for a minute every 3-4 minutes roughly...with a larger intake it would be more like a minute every 7-8 minutes and lead to way larger temp and RH swings between cycles

for a 21 x 11 room you definitely dont need a large intake or filter...ive ran a 20 x 10 , 8kw room with nothing but a properly placed 6 inch can fan during the winter..so a 8 inch fan should be more than enough...the size of your filter is directly related to the fan size, so you just want a compatible size to what fan you decide to run

with all that said, as previously stated..this is not an ideal way to cool a room (active intakes)...its just a cheap bare bones way to do so, that may make more sense in some situations than others..especially in the summer...where i was growing when i was running intakes in the summer it was at 9000 feet elevation in the high rockies and got down to the 40s even in the summer..this is where i started designing and running intakes as it made more sense than ac in that situation. But other situations may be different

and to do this effectively you need to make sure your room is hermetically sealed , as is your passive exhaust and the exhaust needs to be ducted back outside, preferable to a different location than where the intake is located

hope that helps

0.5 gpw to 2 gpw is a fourfold increase....good dat

oops....meant to quote this ....0.5 gpw to 2 gpw is a fourfold increase....

I've been growing for about 10 years, and have always had compliments on my quality, but never really had real big crops. Best was 5 lbs from 4 HPS lights, not bad but not what Don is doing. I was in sales for years and one thing I learned was work smart, not hard. I was a good mimic then, if what you are saying is selling shit, I can do the same. I applied that to what DJM is doing. I copied his shit, same pumps same feeding schedule, but I ran 8 Gavitas, 40 plants in 5 gal pots. CO2 was added and the last and most important piece of the puzzle...VPD. I ran 20 plants with Lucas formula, and 20 with old faithful, H&G. All plants also received Cyco Potash, Cyco Silica, Sweet Raw, H&G Bud XL, and Mother Earth Bloom tea. Every couple of weeks I brewed some Vermicrop tea and hit em with that as well. The end result was 19lbs of straight nugs of Lavender Jones. It was a toss up as far as which side produced more, I think the Lucas side had maybe a 1/2lb more, but the H&G side had more crystals. Thank you DJM for putting this information out for all to have for free. You sir, are a scholar and a gentleman.

Hey just want to say I've read this thread a half dozen times and learn something new each time. I had a couple quick questions as I'm setting up my first couple big rooms.

Now that your in new England has your use of intake for cooling worked, I know the humidity here is outrageous sometimes.

2nd. Was hoping you could recommend some strains that are available from online seed vendors that would work well with this style of growing, if I recall you used to run Chem 4....

Last, how much square footage is your veg room in relation to flowering Space?

Once again we all appreciate and respect your work and send good vibes at you. Life long New England guy here PM me if you need any helping getting to know the locals

He doesnt need help with people knowing him or his product.. thats why he runs away from all the spots where people know him.
...Btw humidty late in flower is not good and youll see why he changes styles midway through his grows lol

Humidity in late flower HAS increased my yield in moldy weed

 

[coldcanna]

People are just here to admire DJMs work, if you don't agree with his style and with VPD just move on, or maybe post pics of your grow that did better than this one? If you couldn't grow weed in high humidity I guess no one in Thailand, Jamaica, Columbia, tropical Africa, Hawaii, ect could grow. Oh wait.... that's where all the genetics we use today come from......

This is the coco section, and not a VPD thread...so don't filter my comments like the social police.

You want to run high humidity in later flower, go right ahead...and I'll do it my way and have no problems....I don't do VPD, so have at it "bro".

It works in the winter..i ran two 16kw cycles using one 9 inch vortex intake ran down the center of the isle.ill update more pics later but here is one of those runs..motorbreath 15

intakes in the winter worked great up here. i ran them from oct up until mid april...after that it was too hot for 16kw..i could have added more intakes but it would have been harder to control co2

any strain will work really, ive ran almost pure sativas all the way down to pure indicas in this system..i prefer sativa dominant hybrids that have decent stretch, long running colas with minimal nodal spacings and dense flowers..but really anything will work, i just will veg and train different things differently..this system does not need a loose sativa to work..the pic showed are from the densest strain ive ran to date..and i lost not 1 gram to mold...its always funny how bad growers like to blame their shortcomings as a grower on technique instead of user error, when the technique is a staple in the world of horticulture and has been for over 20 years.. i guess some kid straight out of highschool with a few plants in his closet understands the science of plants far more

i run a 4kw veg room to feed my 16kw flower room..you need atleast 25% of the lights/sq footage in veg, to properly feed a flower room, without too much down time...with 4kw veg it allows me to chop, transplant next cycle and flip in 14 days or less...you could go with a larger or smaller veg, the only thing that would change is the amount of time they will need to preveg before flip in the flower room. hope that helps

kid...people know me all over this industry , personally , in real life, not just behind a keyboard, and my reputation speaks for itself..and thats why i can move anywhere and be welcomed with love and open arms..and is why i can show my face at all the canna events and get togethers..maybe stop by one and say hi sometime...oh thats right, no one knows who you are...feel free to go around running your mouth though, im sure it makes you feel better about being such a shitty grower

http://msue.anr.msu.edu/news/why_should_greenhouse_growers_pay_attention_to_vapor_pressure_deficit_and_n

Here's a refresher from non other than Michigan State University on VPD for the uninitiated.

Thanks for the quick response DJM it is much appreciated, jumping from a couple lights up to around 20 is a big step, trying to have the process as nailed down as possible. If your trying to make your living in NE your best bet is in Maine, 30 plants for a maxed out caregiver and 6 for yourself. Lots of rural places, it's very cold so your system would be great

 

[coldcanna]

I think you also touched on this earlier in the thread, but if people are concerned with mold you can still run 60% humidity the last couple weeks and as long as the temps stay 65-70 you'll be good

 

[Weeded1s]

@waxy you crack me up. "Could barely pull a p per light" lol n your talking shit. Mind your own buisness.
Like i said in the beginning of this thread to high rh late in flower is no good.
Mold,pm,reduced potency and flavor,and fluffy airy buds.
It must be easy for you 2 to run through life changing what you stand for and what your trying to prove half way through the test/grow!..
That way your never wrong right. Im outta here!
