Michigan Zone 5 Climate so not typically humid or hot per say and cold temperatures can be 5-6 months long. Highest temps get around here is 35 Celsius / 95F and that spike would only be on occasion

My setup is 6000w... so 3.... yikes

At 4 plants that would be 6 gallons of water per plant per day (3 gallons twice daily). Holy damn lol. And that 70 pint really keeps up with the humidity? My calculations on "https://www.hydrotekhydroponics.com/dehumidifier-sizing-calculator" say you would need a 168 pint dehu and 70 is keeping...

You mean basically 170 pints per day? Would either the Active Air Dehumidifier, 190 Pint or the Ideal Air, 180 pint work? I know different pints are rated per day at different temp and RH so not sure what temp and RH 170 would apply to. Also, I know typically Ideal Air is a good brand from what...

How many plants? Just this information is going to help me size my unit approximately as plants expire 97% of water they are given so ill know how many pints are in the air.

Size of room and how many gallons of water per week in total for all your plants in watering?

Hello all, I know watering is dependent on many factors (growing medium, lighting, pot size, environment, etc.) but is it ever, in any inside environment/configuration, normal to water each plant 2 gallons per day? I will be growing in soil indoor and have the room to grow very wide and tall...

Can a tankless water heater get a 2000 cubic foot room (10W x 25L x 9H) up to 1500ppm?

$2,212.95 is the cheapest I can find

$1,061.50 @ https://premierhydroshop.com/ - Ideal-Air Pro Series Dehumidifier 180 Pint $934.08 @ https://shopbvv.com/ - Active Air Dehumidifier, 190 Pint This is compared to like $2,741.99 for the Anden Grow-Optimized Industrial Dehumidifier, 210 Pints/Day 240v

Any opinion on the Active Air or Ideal Air models? I see these in a lot of Hydro stores and the grower I know swears by Ideal-Air. https://www.ideal-air.com/shop/product/ideal-air-pro-series-dehumidifier-180-pint?categoryId=dehumidifiers...

So you don't think that one will work in the link? The Quests/Anden/Santa-Fe (Industry standard I know) is super expensive.

I have a 10x25x9 grow room with 12 plants and 6 x 1000w Gavitas, sealed and well insulated with panda film as the reflective material. Live in Michigan so a zone 5 climate and natural humidity (getting to spring currently) typically isn't an issue. Trying to size a dehu but the calcs online are...

1500ppm in a room of what size? and also is it hard to control what ppm you want at the moment? as I will start scaling up during the stretch up to about 1500 than come down before harvest.

So 20% and in less time so technically more harvests as well which is even more overall yield in a year. How much extra cost in your electricity do you think comes from the dehu, co2, mini split ac, etc vs just running in and out exhaust fans?

@kingromano

How much in your experience does CO2 enhancement if done right like you laid out ACTUALLY increase yield? 5% 20% Higher?

Do you stop CO2 2 weeks before harvest?

So just keep it normal range until switching to flower than gradually climb in ppm? I have 6k (6 x 1k watt Gavitas) lighting in a 25x10x9 room completely sealed (spray foam, r15 fiberglass, vapor barrier, poly foam board, panda film)... is this enough lighting and reflection for 1500? Also, I...

Hello, I am trying currently to decide between running a CO2 setup vs intake/exhaust setup. My room is completely sealed and I do in the future want to use CO2 but for my first two harvests I am transplanting plants from veg (never used additional CO2 just normal air) into the flower room. My...
