yes, all depends on room size. a bowl or pot with warm (or better yet HOT) water will raise the humidity. I wouldn't worry about low humidity, (unless you are trying to do clones), it will get higher the larger your plants get and the more moisture they transpire and hold.
1 of 2 options. get a vented light hood that is exhuasted out of the area (not just out of the room but the house, building); or make your room temp that you are supplying the the intake air from colder via a/c.
o ok so i got the right ratios jus use it in small amounts... sounds good. thx bro3-1-2 (aka 12-4-or anything similar (higher in N and lower in Phosphate) will suffice while in vegatative state. You swap those when you go into flowing (i.e. 1-3-2), but keep up the nitrogen a few weeks after the transition to minimize leaf yellowing/ loss.
with just h20, no. You dont want to over do it though. you will want to refrain during the mid and later flowering periods as it adds to the risk of mold, etc. If you have good humidity control then you should be ok, but don't hold me to that.
Any substance sprayed on the leaf, even just h2o will be phytotoxic
Sorry I'm a keep em green grower, I flush everytime I water and I feed to the end so someone else will have to help ya
you should be watering for "PLENTY" of run off, in a 25 litre pot I would be watering with 50 litres
need lots more info about your garden and pic's please
10 in one contaner wont work because the roots are gunna fight for space. if i was you i would transplant a couple of them (the healthy looking ones) into seprate containers.
iv seen this tried a couple times, and succeed once. you will most likely get 1 or 2 dominant plants that strangle out the rest of em. but yes when the days get shorter ( will happen depending on where you live) the plants that are left will flower naturally.
you cant really guess that but if it doesnt sprout after about 7 days its dead.
