Something about mapito, I use rfx-1 As you now, rockwool holds water very good. The danger with rockwool is it holds little oxygen when it's wet. (like soil) Your roots need oxygen, a lot of it! The foam in mapito or rfx holds almost no water but a lot of oxygen. When mapito is full with with...

Sun rise and fall is something the plants don't give a fuck about...You can use it to prevent condensation on your crop, but when using the opticlimate, I rather use the slow cool down function and pre heat function on the machine to prevent condensation. Therefore I give plants the full...

Indeed, I switch to walk the walk :banghead:

Hey Yaacov. Yes i use 2 pumps with a timer. One in my reservoir and one in the growing area. After 4 runs I switch back from fabric pots, back to crates. nothing else changed. The room is down now. In week 4 of the 11e run i had to break down. Somebody had a great idea to put a meter in the...

Set controller from dimlux to dim at 27gr. Set opticlimate higher. When plants look happy go up as fast as they can take.

1. No. Depends on the location. In some growrooms you hear everything, in some you don't. 2. Almost the same answer. No i use iso max inline fans. Rule of thumb is that you can refresh your room 5x/hr 3. Passive inlet but very small. (under a door or something) You need vacuum and keep co2 in...

Google for adiabatic coolers and you find wat your looking for...

Sorry.....Don't want to fuck up this topic......It's about honeystuff, not dimlux :)

In Januari 2014 they will have 1000watt double ended aircooled light. The bulb is surrounded by invisable glass to cool the bulb. The boost goes up to 1200watt. I saw this on a show in Vienna....

First let me explain something, A cold water fogger doesn't make your humidity go higher. It makes a mist of very small waterdrops that are lighter than air. When these drops evaporate in air your humidity goes up. This takes time. When you don't see the mist, the drops are evaporatet. In most...

No Bobby, At the start of grow i regulate temps and humidity with the lightcontrol. When the canopy is closed, the humidy is 60/70% with all lights full on and cooling running for the whole 12hour daycycle. Moist air has an effect on cooling.

@tweedy, Maybe this helps? It's not the exact same product but i think it might do the job. Together with calcinit it should be a complete fertilizer. @clockworx and Growmaster , Thanks for nice replays...

Ok, i think i got it....It's like a coil. Opticlimate also makes the same unit in a split unit version for people who don't have enough water. The watercooled version is 10% more efficient than the split unit. Me Bad. Thanks GM

Could you explain what a pigtail is......:banghead:

The growroom is not in a house :) It's in a barn. What should i heat with it than? The units are fahrenheit. When using tap or wellwater the water leaving the unit is about 104gr F. I try to explain.... There is a big differents in using fresh cold water and reusing the warm water. This is also...

@ttystikk , when i compare it with a split unit, -A split unit cools the hot gas with air (outside) -The Opticlimate cools the hot gas with water. Water takes up energie much better than air, making it 10%more efficient. Here a little piek inside I don't reuse the warm water. I know people...

You will learn Nuttso.......you think so much ;)

That's the way i do it more or less Nutsso. These days i use a bit less A (N) The fan is separate and is not part of the opticlimate. You refresh 5x when not adding extra co2. When you add you dim the fan only to get a little vacuum for smell. You can put the opticlimate inside the growroom...

When raising co2 levels, the plants stomata tends to close more, making evaporation more difficult. More than 1500ppm is useless for full grown plant. By calculating VPD you will know or your evaporation is good and stomata is open.

We are still alive :) Pots are a try-out. Seem to work great!
