New room

This is definitely a newbie question but yeah im new to this.
Whats in the two water bottles with the straws attached? And what do they help with?
I have seen this a few times but i have no idea why people are doing it.

TBH I didn't used to think defoliation was a good thing, but I first experimented with it in veg and noted how quickly the plants blow up afterwards. Secondly I tried it on some of my really leafy strains at about week 3 of 12/12. I learned that the lower bud sites developed much more than if not defoliated, any site more than about 12 inches below canopy was better with defoliation and I didn't notice any sign of loss on the top for the lack of a few fan leaves.

Now I do my defoliation in veg from the bottom up, removing all fans except the top two on each branch, when the plants are about a foot tall and again about 4 - 8 days before I move them into flower. When I defoliate in flower I work from the top down, only removing large fan leaves that are blocking lower growth and leaving lower fans that can serve as a nitrogen reserve in later flower. I like to see those remaining lower leaves fade during ripening indicating the plant is using mobile reserves of nitrogen and I am thus not over feeding.

When defoliating I find that too much lolipopping is counter productive as those lower sites are getting more light now. Only remove lower branches and sites if they are getting no light after day 21 of 12/12, or after stretch as some strains it may be later like GMO has another 14 days of stretch over any other strain I have ever ran. That strain will grow right up into your lights if you aren't expecting that lol. I find that leaving the lower branches until stretch is finished can help limit excessive stretch on the top a little.
Perfectly explained!

your a advanced grower you can research girdling, and girdle a max of 2 mm, 3 weeks prior to finishing, this will restrict the carbohydrates heading back down to the roots and boost bud dry matter, the girdle will heal over with cambium with-in 4-10 days, dont go wider than 2 mm and don't go too deep, some times 2 girdles can be done on long flowering plants.
very interesting, have you ever done a "partial girdle"? like, cutting 3/4th of the cambium? I wonder what that should do, ie. not to completely shun off sugars from the roots but just toning it down a bit to get more sugar into the buds...

Could it also be done non-intrusive, e.g. by pressure (wire, hose clamps...)?

Ive accidentally broken the mainstem in times the plant was still small... its been 75% severed (open wound) so the cambium was intact only at one side.
Taped it swiftly, and also used artificial bark to shield the wound from air.

the plant grew just fine... maybe 25% is still too much leftover...

there's still a huge scar in the outer structure, perhaps limiting/preventing some of the downflow... my guess is that the plant recreates that place in order to, again, reach a balanced equilibrium of up- & downflow.

Yes definitely Bending , folding, breaking of stems that in turn ruptures the cambium layer do act as a partial girdle, which heal, they do have some of the same benefits of a full girdle, especially if done multiple times every 10 days up the stem, say 3 breaks . Every year on my family Trusts Kiwifruit orchard we girdle twice every growing season , the dry matter benefits are huge, as fruit payment is based on fruit dry matter, I have also girdled many a cannabis plant with good results, I have tried wire ties, that cut into the cambium as the stem grows but this is not very effective, the most effective way is to fold a stem horizontial, then lift it straight up again and run a sharp razor blade around the stem cutting the cambium layer at the fold, wiggle the blade as you cut to spread the cambium and make a slightly wider cut, 1-2mm wide, and then fold it down again and leave it to heal, water on potassium silicate after, and repeat the same procedure after 10 days a bit higher up the stem. This should only be done on stems at least 5 mm thick and not the main stem/trunk, but the main branches, say the 4 largest.
