My Mystery Indica Reveg

Checked on my dehumidifying experiment and the ice had completely melted (I didn't change it when the lights came on as it was still 3/4 frozen) so I decided to replace the ice and measure what had been drawn from the air.

In 9 1/2 hours or so of lights on it pulled 175 ml (6.16 fl oz) from the air, in excess of quadruple what it pulled during 6 hours of lights off. Now, I don't know what anyone else thinks, but that sure seems like success to me and I see no reason not to continue dehumidifying this way until harvest.
 
Would be awesome to see it in action with a cheap hygrometer :) Great idea and seems to be working, would be nice to see how much that 175ml equals in RH :thumb: very cheap to setup and continue to run compared to the ongoing costs of a dehumidifier and its power usage, well one that actually works anyways hehe, the little cheap jobs do nothing.

I'll have to hunt around and see if I can find a hygrometer to see it in action. I'm more than pleased with the results and happy to see that the idea worked, but after drinking so many cold beers and seeing the condensation coming off the glasses and bottles, I had no doubt it would and I'm pretty sure that's where I got the idea in the first place :)

Although this is a non electrical DIY dehumidifier, there really is not all that much work involved in running it and I would probably be more than happy to just change the bottle once a day at lights on during the flowering stage and, tbh, I didn't notice an issue with the Rh during veg.
 
While she was sleeping, another 135 ml (4.75 fl oz) of moisture was pulled from the air. So, in the last 30 hours 353 ml (12.43 fl oz) of water have been extracted from the atmosphere and there was no moisture on the leaves where they overlap when she woke up. I should add that this has been a problem recently, thus my urge to dehumidify.

The tent was somewhat cooler than I would like when she woke at 13.5 C (56.3 F), but I can live with that. The main thing is that the air temp stays up during lights on.

Whats the lowest you think a plant can take at dark cycle before it hurts or kills it

That really all depends on the strain.Those originating from equatorial regions (I.E. sativas) will have a very low tolerance to cold, whereas those from places more distant will be more tolerant. As a rule of thumb, the cold will slow down growth and adversely affect yields. I have grown some outdoors in Australia when there was a very cold autumn and that definitely stunted their growth and yield was low.

A couple of days of cool temps won't harm them too much, but anything below say 5 C (40 F) can result in tissue damage and sustained periods at this temp will kill them.
 
Fortunately, this current cold spell is expected to be short lived. If it looks like we'll get any extended periods of freezing temps I would certainly heat the environment and I will definitely close the damn sky light.
 
Here's a good little tip from a site I very much like.
Tip: Use Temperature to Help Control Growth!

Cannabis generally prefers slightly cooler temperature at night and warmer night temperatures will tend to slow down upward growth. But... you can occasionally use this knowledge to your advantage to help control plant growth!

By artificially raising temperatures during the dark period, it will slow stretching plants that are growing too tall too quickly. This can be a helpful way to reduce the "stretch" if you're growing in a situation where you don't have a lot of vertical room. And never forget about supercropping, the ultimate way to break down the height of your plant at any time.

By keeping temps a bit cooler during the dark period, you will actually encourage your plants to grow as fast as possible.

I had shoes but the 10 miles in a raging snowstorm. True story ! Lol

:rofl:

I knew it!

Got your number! :)

I moved to OZ as a child and was forbidden shoes at first so my feet could toughen up. Damn, that gravel was murder for the first few weeks. I was like some dancing, prancing little pain fairy.

Fortunately, I didn't live in a box on t' side of road.
