Cooling Water with Ice Bottles

without a chiller your not going to get 20 degree sustainable drops. you would literally be changing out your bottles every half hour MAX! if you can get your temps down to 80ish by adding a fan to exhaust your room pick up some stuff called dutch master ZONE! this stuff prevents root problems at damn near 80 degrees it also help with nutrient uptake due to the higher temps. If you can get your room cooled down to 80ish a 2 liter bottle of ice would need to be changed roughly 1 to 2 times during your lights on period. your temps should lower considerably without you lghts on. hope this helps a little bit. the zone is roughly 25 bucks for a liter and a liter last me a whole cycle on 3 systems. all 3 of my systems have 30 gallon rezs that get changed weekly. its like a 5ml to 5 gallon ratio.

If your water temperature is 90 degrees that means your grow room is this hot or hotter as well. No point going to all the effort of bringing water temp down if the grow room still gonna be stifling. Might be better to be saving towards better ventilation, AC or such.

the area is going to be my clone and veg box (roughly 2'Wx3'Lx5'h)(200w CFL). i went ahead and ordered a 4"x12" Carbon filter today. I am going to pick up one of those $100 ac units at walmart and rig into my room. I have not started my system yet, but I have been monitoring my grow box temps/humid and the room. I live in NE Texas and the heat has been a winch.

I am ordering Papaya-FEM from Nirvana Monday, I am sure it will take a couple weeks to receive. I will be running an aero/Ebb&Flow/Spray system of my own design in which I will post my cycle when I get the nuggets.

My Flowers will be in a different environment (5Wx5Lx7H) running 6 : 5-gal bubbleponic: with two 600w HPS shared amongst the 6 plants.

I will get me some of that Dutch Master Zone. Sounds like a win-win situation anyhow. (http://www.horticulturesource.com/pr...roducts_id=184)

Wish me luck, thanks for the replies, and I am running in the background until I get my nuggets.

Hey DrtyBngWtr,

Does the DM Zone change the TDS/PPM of ur solution at all? Is there concerns for this and how do you allow for these changes if so?

Thats why I said he needed to get an exhaust fan!

Yes it does, but its very minimal. it actually has an NPK ratio of 0.06 - 0.0 - 0.15

I use it with my Humboldt Premium line. You add it to your water let it condition it for a few minutes. then ph your water down if need be. then you add your nutes. like I said its very minimal and I personally dont factor it in.

Mind you I always have a pump calculating water when I do a rez change. nutrients may settle by the time you get them all in. A pump keeps everything constantly moving and mixing.

In my fight to lower temps I came up with this x8 one gal jugs of water froze them and I swap one every
12 hours and at best it lowers it 5f so i came up with a better way I plumbed a pump on the outside of the
Res to run water to a ice box its sold on the advanced nutes website, it has a 6in in and out you hook a fan
To it and it also has a 1/2 in in and out for water to run through a radiator of sorts works great the fan cools
The water and the pump running outside the res isnt going to heat the water.

I too was running high temps in my res...addressed the environment with exhaust fans and a portable AC and now my res temps stay in the 70 degree range when I test. I know it is an expensive fix, but I highly recommend it. I found a heat pump type of AC, Heater, and dehumidifier...14,000 BTU's for a touch under 500 bucks. I live in an un-air conditioned apartment, but the ladies got what they needed.LOL
