New Grower First Grow - 4 Different Auto Strains in Coco

Here is a visual that may help. Cold air is more dense - The air molecules are packed together tighter so less room to hold water molecules:

Warm air is less dense - the air molecules are not packed as tight so there is more room to hold water molecules:

Hope this helps.

I suppose I need to mention what RELATIVE HUMIDITY is; it is the ratio of how much water is in the air vs. how much water it can hold at a given temperature. So if you have 50% relative humidity @20°C then if you warm the same air to 25°C without adding or subtracting any water the relative humidity will be lower ~ 36.9%. Same amount of water just different air density (temperature).

This is why dew point is a more useful metric when trying to convey to people how sticky or dry the air is going to feel outside on any given day: it's not as important to know a second variable (temperature).

Do I need to make a special effort when misting not to allow any droplets to fall on the leaves? I'm reading conflicting things about this (as usual...). If it slows down any processes I'll try to just mist the walls of the tent. I'm using filtered pH-adjusted water. Humidifier arrives Friday and, hopefully, with it in the middle of the tent, this is no longer an issue.

My fan blows so hard the mist hits me in the face instead. I just spray down the walls then observe the RH.

There are only three real problems with misting the plants themselves. Water droplets can form a lens that focuses light on the underlying leaf surface. If the light is strong enough (not likely indoors) it can burn the leaf. second is more likely, the calcium in the water can build up on the leaf clogging the stomata as it evaporates off; this is only a problem with hard water and it takes a lot of deposition to cause the problem. That aside it really is not a problem misting the plants. The final concern is Powdery mildew. Wet plants are more susceptible to PW and this is a real concern!

Hmm the second potential problem could be an issue with my humidifier... I won't be using distilled water, but filtered tap water (maybe with a splash of H2O2). 30 ppm. Hopefully I will only be using the humidifier early each cycle before the plants get bigger and can transpire more. My water is on the high side of what is still considered soft, or just barely hard.

I'm hoping this won't be an issue for me as there won't be enough time for calcium/magnesium deposits to accumulate and clog the stomata.

Day 8: Ramped up nutes to 50% of what GH recommends for Week 2. Diluted it significantly for the new FuSt. It's Day 6 for SC and Day 3 for FuSt.

Little concerned with how the SC is stretching...

Pics taken just before feeding, so the surface looks a little dry.

Edit: Helmet just fell off and the tiny fan leaves are crumbled up like a piece of paper. Should be flat in an hour or two I think.

Ugh... I just saw this: https://www.growweedeasy.com/wp-content/uploads/2014/12/start-week-2.jpg

That's practically my exact setup with FloraSeries, coco, and autos, on Day 8 like my photos just above. Think I spent the first week way too light on the nutrients. Hopefully this won't result in adult dwarfs.
