Also US based/tarrif affected? HLG has good solid us made lights with good after sales but at fairly premium price.

This sounds like a pro op. You should give a bit more info for good advice. How much weight can you hang from the ceiling, how stable is it? How do you control climate? Venting? From lung room or outside? If outside is it predominantly cold or somewhat hot? How high can you grow? Do you have any...

Saving on CO2: that just means less photosyntesis. The stomatal regulation of of green light quoted by mammoth just means that green reverses the blue response, stomatas have less tendency to keep open, in my book not really a good thing.

Depending on the the driver you may be able to just switch the dimer. The driver itself shouldnt have a problem with 5%.

Very nice thermal specs on hose boards.

Its interesting to see that they still use 630-640nm diodes for their reds. T, youre an oldtimer do you have any opinion on 640 vrs 660 for red supplement?

Thats some hairy nugs!

You can always try adding to your lungroom without using a humidifier. Try this for a diy humidifier, hang a wet towel or similar fabric with the bottom in a container with water. Add some airmovement thru a fan to the towel, it will dry the towel while the towel wicks up more water to remain...

For a single tray, in an open space without reflective walls id do the same as you, go for 40w per foot. Theres more light lost in the sides. A tent is better at bouncing back the light. Also the gavita is a bar light (iirc) which spreads the light a bit better. Dont know about your current...

I would probably try to finish with what you got, only see downsides to changing really and very little upside. Dialing in light intensity and everything the last two weeks is going to be a nightmare which only risks the finish and end quality. Its of course possible but i wouldnt advice it.

Led plants drink and transpire less than hid plants. So they may need a combo of a little more heat and sometimes a bit more nutes; not in totals but like in concentration; drinking less of a stronger juice. But in any case transpiration should be the first priority before messing with nutes...

OP: i would also check carefully SFs par maps. Doing calculations by watts is usually quite fine but its likely that this light will bleach tops if they are too tall as it concentrates the light to the centre a bit; this is why i would rec a bar light, or that vipar that has lenses that even out...

300w is absolutely overkill, especially with that little headroom. 120 would be pretty standard in that space but always good to have a bit extra. Youll need some type of bar light to spread the light out over the space, a single board with that little head room is not a good fit. 30-40w per...

Im by no means an expert but ive heard hlvd has a specific pattern of affecting old growth more so if it was that there should be a pattern of less trikes the lower you go. Cant confirm though, also seems to be the natural pattern of trike

True but unlikely if its allways the same clones of the same mother with no influx - not sure but thats what it seemed like in first post
