Smallgrow, I'm interested in researching this further. I've been following guidance from the manufacturer of my LED grow light, which says the opposite.Â

have a look at these two videos Sperocles
The Chad Westport one is on an associated topic but if you listen carefully they speak to light intensity at different stages.
All of these people are professional experts in the field and have excellent and current information. So much is changing in Cannabis growing almost on a daily basis as more professional research displaces the old Bro science

Why am i getting condensation from light level down ive ordered a dehumidifier a 6 inch exhaust as i was told i should have never been sold a 4 inch for my 1.2mx1.2mx2m high tent. I have 10 plants in tent just now my temp is 30degrees and humidity off 50%. When 6 inch comes i will put the 4 inch in for more air but id be doing inside bedroom is that ok. My rooms in flat are all 21 degrees. Any thoughts team

The cause of the condensation may be from couple of things. A lot of plants. You have ten. They all transpire and that puts water vapor in the air. That along with poor ventilation may be the problem. If you have a temp drop at lights off that is drastic enough that might do it as well. The temp difference of 30 C inside the tent vs 21 outside could also be a factor. That's only 16 or 17 degrees so, prolly not but along with the other factors it could matter. Do you have ventilation fans moving the air around? You need them to avoid dead air spaces where moisture can collect, especially with 10 plants. How big are the plants?

Either your dehumidifier is not working at all or not big enough.
Use the bedroom as the lung room and dehumidify that air. Its not easy or cheap to dehumidify air that is 21â°C or lower so your approach for more air c/o faster is the right first step. That will increase room temps a little but drop tent temps a few degrees hopefully.
You need to aim for much lower than 30â°C in flower unless running supplimental CO², which is simply not worth doing.
Ideally 22 to 24â°C and 40%RH....Lower again on the RH last 2 weeks.
Youll also need a lot of airflow across those buds.

Areas susceptible to high humidity and or rainful during mid to late flower really makes it difficult to grow large dense buds without bud rot.
If this is the case with where you are growing, and it appears that is the case, indoors is the go.
You could go one step further and utilise a reasonably well sealed room and incorporate automated climate control, which will give you the best weed in town, but it costs a bit to setup and a bit to pay for the electricity.

I am growing in a 20 gal. tub, plants were moved from a 5 gal DWC bucket, one plant wilted and died, I think I did not have enough water or nutrients when plants were moved, they were in the first week of flower.
Remaining plant is now drooping, water level is at approximately 6 gallons. Using Advanced Nutrients, PH perfect with voodoo juice, Bud candy, Big bud & Bud candy. What could be wrong with my plant?

The two plants I have have stopped growing taller and they're filling out a little bit but I have a hot climate and they're in a pot outdoors. I need advice on whether it's time to move them indoors and do 12 on and 12 off with the lights. Just curious as to what people think of what I should do the next day just far as cutting leaves and moving indoors. Thanks for your help
