Hi John,
If I have a mother room of 24'x40'x10' with 100 mothers, 12 600W MH lamps - what kind of system do I need to adequately remove humidity? I'd like to retain between 65-75% RH and about 70 degrees F.
By the way - Woodsman sent me here.
Thanks to both of you. I have also been very busy but am focusing on this full time now.
Just to clarify - the sealed room with RDWC is for mothers only. There will be separate flowering rooms with ebb/flow tables, sea of green. Each flowering plant will be a short clone that has rooted and will receive minimal veg-time. So for the room we have been discussing (mothers/clones), there would be no "night-time" and therefore no temperature fluctuation - only light for 24 hours and a constant temp/RH. Unless you recommend 18/6...
Do these recommendations still hold with these systems I intend to use?
For mothers, you prefer higher temperatures and lower RH (80F and 50%RH).
For flowers - first two weeks: high temp and high RH to boost growth (flower production?). Also very slight reduction in nighttime temperatures for the first 2-3 weeks. This low temperature difference between night/day will help to keep the plants short, especially important for sea of green.
Water temperature below 75F
When you say the HVAC would not run much at night, is that because you don't need to cool any lights/ballasts?
Got a room almost done and need some help deciding on cooling lights with outside air or with a/c also wondering where I should mount the mini split inside the room! A/C is aura 24k btu mini split we are running 6k electronic hortilux ballasts all hung on ceiling.... any help or suggestions are welcome! I've attached a diagram of room setup so far
Hi need some advice/thoughts, my plan was to run my room with the equipment below, given what i know, i.e specs exhaust and induction i thought i had all bases covered, turns out the i don't. Temps
outside are no where near where they should be and the room is showing signs that it could over heat. what is my AC options here. I have very limited space left and $ are on the thin side.
Room:
9ft x 11ft
reflective insulation
water chiller (resun cl650) for RDWC
4x1000w , mh- veg, hps- flower (maybe combine)
Vertical bare bulbs
Environment:
Autopilot greenhouse master controller
1052cfm exhaust
550cfm intro fan
Cooling = 0 degrees outside
Hey CannanisJohn and fellow farmers,
Took a few hours to read over the thread before asking my questions and I am doing my best to follow the complexity of the different cooling options available and it seems like some of my problems have been discussed however I really want to hear your opinion.
My 3 Ton Ideal Air just shit the bed and we lost an entire room so we are sick of dealing with these hydro-store brand A/Cs that seem to be all built like shit and unreliable.
I am in the Northeast and it gets both VERY COLD and VERY HOT. I really need a setup that can perform at close to 0 degrees outside in the winter and 90-95 degrees in the summer. Reliability is paramount.
We would prefer quick-connects so we can install without any tech but it seems that many of these systems still need extra work. We have successfully installed almost a double digit number of Ideal Air products and so far we have had 3 units fail and got lucky and never lost a room until this past weekend when the A/C froze up and failed for good after temps dipped to single digits.
The equipment we use work unbelievable in terms of quality of product but the ballasts are all inside the room (single assembly) and
We have two almost identical sealed flower rooms with no air cooling. We try to run low 80s during the day and low 70s at night.
Room A
Total Wattage = approx. 5000w
Size= 12 x 12 x 9
4 Gavita Pro 1000s turned up to 1150 at least for 1/2 the flower cycle
1 Gavita Pro LEP Plasma is said to put off about 300w
4 Kessill A350 LEDs
Dehumidifier (forget the brand but keeps the room at about 55%)
IdealAir 3 Ton (just shit the bed)
CO2 by tank controlled by iPonic 600 controller
4 circ. wall fans placed at varying levels , all at light level or lower
A/C Placement - outside 15 feet below the room on the driveway bolted in concrete (might have to make sure it is above the snow level from reading your post)
Room B
Total Wattage= approx. 4200w
size=10 x 11 x 9
2 Gavita Pro 1000s turned up to 1150 at least for 1/2 the flower cycle
2 Gavita Pro 600s
1 Gavita Pro LEP Plasma is said to put off about 300w
4 Kessill A350 LEDs
Dehumidifier (forget the brand but keeps the room at about 55%)
Aura Systems 3 Ton, seems more reliable than the IdealAir but still has problems w/thermostat and outdoor unit still freezes up sometimes even though I believe it is rated for cooler weather
CO2 by tank controlled by wall plug controller (pending iPonic)
4 circ. wall fans placed at varying levels , all at light level or lower
A/C Placement - on the porch about 15 feet away, about a foot from the siding, fan facing out towards the street, lineset goes up to the celing and back down about 2 feet into the room
I see alot of talk about water coolers being used, is this the same as a swamp cooler? Could these help us take stress and reliance off of the A/C?
We are pretty set against using outside air but is there anyway to use inside air to help cool the room and take stress off the A/C using fans and venting to evacuate some of the hot air?
We were looking at quick connects and found the Winchester's that seem to be commercial grade A/Cs that quick connect and also have a heat pump.

The manual talks about needing to have a gas fuel line to use the heat pump? I thought the outside unit would automatically heat.
Any help is much appreciated!
Would It be a good idea to place the condenser in a garage if the outside temps get below freezing (Colorado) and then super hot in the summer? Just trying to figure everything out before I start setting up the a/c just in case we miss something crucialThose still require install by licensed contractor or warranty is most likely void.
Heat pumps can only heat so much when it gets cold out so either electric or gas heat is used to supplement.

Also would freezing temps be a problem while cooling lights with outside air? As far as condensation and such?

Thanks man, I really appreciate your feedback.
I do not mind having an HVAC guy come to install the units if that is what I have to do then that is what I am going to have to do.
Based on the information I gave you can you give me any recommendations on systems or setups?
Will a chiller ran to ice boxes still need to be heated?
Can I use a single chiller to run multiple ice boxes in these two rooms (I would assume that the light cycles would have to be the same)?
I noticed you said I could use electric heat to keep the A/Cs warm. Would this be something I buy in addition to the A/C unit?
I have an outdoor 110 plug available for the A/C on the porch and could run something for the driveway unit as well.
