Well the reason why I'm interested is because it also heats up the res which at times (for me) is not warm enough.

I'd like to try this one day. Maybe have the water pumped around to cooler areas.

How's that? I was under the impression that ~20 gallons of water could easily cool up to a 500W worth of cobs without heating up the water too much (since specific heat capacity of water is very high) to degrade nutrients.

My guess is that happens only when only green light is provided in isolation.

This probably sounds stupid but how effective would it be to run multiple high power cobs that are run through with the water that fills the hydroponic reservoir? Heat the water, cool the chips. I had this in the back of my mind for several years.

I don't think that's true. The plant benefits from all the colours but not all are necessary even for CO2 uptake. CO2 uptake is regulated by stomatal contractions which is affected only by temperature and humidity afaik. Regardless of which color you provide, the end result is the same...

Fresh weight is the same as dry weight? lel

How did you burn them out? I'm not sure if my strips are gonna last as long as they are supposed to. I mounted them on 1/8" wooden board and it gets hot around 40C/104F. I don't think I can even add a heat sink at this point.

Thanks. I didn't wanna peel it off cuz I'm afraid the adhesive might wear off and I might damage the chips because the strip layer in between is really, really thin and looks fragile. Also, I don't know what to put as replacement. Not too bothered either. I'm testing the vegetative phase of...

Had a minor fuck up. The strips were supposed to be alternating but somehow I put them in 2's.

Chromosomal differences. Basic genetics. A thousand hybrids from a billion generations is still a rare event. There's a reason why hybrids aren't that common in nature and why parents of a hybrid have different characteristics, fit for their specific environments. Seems you don't know that...

Question for those who build their own LED panels, How do you put ingress protection on your systems, if any, especially waterproofing?

Reduce the amount of light for the big ones, and increase light on the small ones?

Until they find a living thing that's not made of cells. Off topic but, its detrimental to scientific advancements to nullify certain aspects of a concept based solely on previous understandings of how it works. For many centuries scientists thought that an object sitting still on the ground is...

The most common result is a sterile offspring, followed by severe defects. Unique adaptations are relatively rare but possible.
