So, u don't need a mister. Waste of money but tat money towards a dehumidifier which will be needed much more, as ur crop expands it will give off vapour (LVPD comes in) and ur tent/room will be like the amazon.
If ur in a tent. You can easily control RH with a wet towel hanging from the bar or using your exhaust fan on a timer. 5on-15off or whatever holds the highest RH for you. Once you are above 65-75 for veg bring it down in pre flower to 60 if u can and getting it down to as low as 35 in fat/ripening..I don't do this, I can but it cost way too much money. And for the lil extra resin and benefits don't outweigh the cost of running my 300w dehumidifier. So, I barely ever run it unless I have to. Ppl in thr likes of cali grow in high RH they have great ventilation. You just gotta rep tat indoors. So getting rh up is easy. Keeping it down will be ur issue when u get to it. But if its high just super ventilation and fans blowing in/over/thru ur canopy.

Hey there.
So, VPD is very advanced and as a new grower. Really you need to focus more on the 101s / DLI feeding/ lots and lots others. VPD is a combination of a lot of dif things. Heat, pressure and so on. So, learning the 101s and what's more important for new growers will then enable you to get a hang/understand VPD better. As you have an even more important thing than vpd & tats LVPD LeafVapour

Flushing with RO Water (EC 0,0) or tap water (EC 0,8)?Hi.
I think, it's 1,5-2 weeks before they are ready to harvest.
Tell me, if you see something else in the pics. :)
I want to flush them now every 2 days with only water.
I have the opportunity of RO Water (EC 0,0).
Should i use the RO water or normal tap water (EC 0,8)?

77 days old autoflower, up to this point is personal taste or still there ways to go?
I majorly see milky and a few ambers trichomes, correct?
Those white pistils are due to the foxtailing, so is not a good metric.

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

How do they work? I assumed that a 2 week timer that runs out would result in someone winning lol. Isn’t that why the timer is there or am I an idiot? I feel like it should be specified somewhere if not to prevent confusion for new ppl
