Hey guys so I'm just curious if once I get into flowering would it be alright to add this fluorescent lighting shining from the bottom upward would it be beneficial do you think it would help keep from having larfy buds at the bottom
Side lighting is always beneficial. Well unless you overdue it, but that's not gonna happen with those tubes.

Im on another forum where a grower just tested his last run with minimal side lighting, lets just say it made me a believer.

@Renfro also uses sidelighting in his rooms, but hes growing fkn trees, so every bit helps in his case lol

What temp on the leaves with led
Well I don't like a LST thats higher than 82 or lower than 72 but your exact number would depend on VPD. It's just a lot easier to get a higher LST with HPS than LED due to the infrared light in the HPS. If you are running supplemental CO2 at say 1200 PPM then you would want to run on the warmer side to take advantage of that.

I RUN A CONSTANT 81F ROOM TEMP AND 61 HUMIDITY

Well save your money next time. You being in the room breathing puts out more CO2 than one of those bags.
If you look at these pictures I feel like the exhale bag is still beneficial it will add some amount of c02 and it will be sent straight st the plants I know that CO2 is heavier than oxygen and everybody has a mental image of what they see the gas doing but I believe with the way I have it set up it'll settle settle down low after it's left the tent settle in the room

There's calculation you can do to achieve vpd with the numbers I gave you??
