"Bulbs that fall short", I built a stand with a single bulb holder, place a light meter about 12" below, check the reading from every bulb if the bulb has lost more that 8% vs new bulb, I would keep it as a veg light, some lost 15%(bin them ones), guess hot veg room, on 24/7, some on for 12-18 months.What do you mean by bulbs that fell short? I assume you have a way of testing them?
Have you thought of building a true dome of lights that literally surrounds the plants........maybe the top 3 feet......a dome that can be dropped down on top of them, and of course can be raised as they grow. Light from every direction.
I see you've thought about it.......how could you not? It would look like Close Encounters of the Third Kind.... ;)
How long would it take you/how much effort? Let's say it was 5ft x 8ft and hung down 3ft all around.....
Possiblejust a quick question, can you hang a quantum boards vertical, so you can turn them on week 3-7 in flower as a side light, dimmed down to 60%
For the energy and price of the cheap 2ft x 2ft panels, it could give your plant a real boost, would need to move the driver and screw the panel to the wall, 2-3" space for airflow( between wall and panel).
Just not sure how easy this would be.
That is a good question and the answer is no, you don't need the right light spectrum.do you not need the correct light spectrum for grow lights?
i have no clue, just asking.
Spent about 2 hours building the light, just need to test, the connector their to connect the fan and the fan hole needs to be drilled out.A friend loves the results from my grow lights and ask me him one for a 80cm x 80cm flower room
but would like to include a veg light(turn off/on 5 of the bulbs )
so I have the blueprint and I will build the led tomorrow, cost less about £90 including the fan, total watts about 260w

Is that 100x like 40'000 - 50'000 lux?
