urgently need some advice here

[Monmon]

Hey guys, ive started a grow diary, black pearl vs Purple diesel, but i have encountered a problem. I know humidity has been covered many times however after reading the majority of the posts i have yet to stumble on one pertaining to me. Basically my humidity is stuck around 25% and I cant seem to raise it without taking the temperature up aswell.

 

My setup is a 1.6 by .9 by .5 m grow tent with a 600 W MH globe. The globe is sitting at the top of the tent as far away from the plants as possible. I have a 2*6 inch exhaust fans, one sucking, one blowing and a basic computer fan airing the plants. I have tried the wet towel, the spraying bottom of tent, a steam vaporiser and I cant seem to keep the humidity up.

 

With the lights off, and limited fan use, i can get the humidity up to around 55% with the steam vaporiser (humidifier).

 

As soon as the fans go back on when the light goes on the humidity shoots down again. Ive tried turning some fans off and keeping some on, but the temperature just gets too high.

 

Im pretty baffled

 

I also now officially hate growlush grow tents.

 

One more thing, my plants are definitely growing slower due to lack of humidity.

Hi Monmon,

 

Quick reply - have you tried putting a soaked towel (wet) in your grow space?

 

A tray of water perhaps ?

Hi nitty ta for the reply, yah i tried the wet towel method. The sucking of the exhaust fan seems to be the culprit but as i said, i cant really turn off any fans otherwise the temperature rockets.

Im seriously about to just take them out of the grow tent and relocate.

if your intake is in a vertical posi put a sprayer behind it or get an evaporative cooler. They only cost about 90 from crazy clarks

While their young, just spray them a few times a day, but dont leave big droplets on the leaves, acts as a magnifying glass with your light.

 

Other than that, just keep on top of the watering, and as they grow bigger, they use more water/more leaves/ more evaporation, humidity increases.

Your 600 is a little to large for your grow area.

check out the calculator

Why don't you like the tent? I'm about to pick one up myself.

 

Try sitting trays/buckets of water inside the tent to increase ambient humidity.

Hey guys, once again thanks for the helpful replys. The lighting calculator is particularly helpful actually. If only i had found that before i got all my equip. damn.

I have found a sort of fix, i place a warm damp towel over the vents of the steam machine, so the towel steams and spreads in a larger diameter. Anyway the moisture levels with lights off are around 66% and with lights on can vary anywhere between 50 and 28%.

 

Ive done all i can really do, including spraying the room, so time will tell i suppose.

 

Gills do you think I should relocate. Not sure if i have a space big enough but can always try..

 

cheers

I think you really need to look long and hard at your situations either go larger or change your lights. When you flip to 12/12 it wont be easy to control your environment. Work out which will be better for you to go larger or change to a lower lighting system.

sound advice.

 

thanks for the help
