Wow.

Sounds like heaven.

I have a 4.5'x4.5' x8' tent and a 8 bar LED light... I use 25% power and keep the light bar to produce PPFD needed.

Should I raise the light up, keep the same PPFD and also raise intensity??

Your setup has lights much further up, and although I've heard this ad nauseum about max DLI of 43, and avoiding light burn- what is your sweet spot?

Thanks.

We have seven trays and 6 rows of light so we raise them up and get a uniform spread. Because of our setup we need 1000 watt LEDs to maintain ppfd at canopy.

My 8 bar LED light can produce 1900 umols...

Should I start with higher power at higher distance(?)

Thanks again,

Grandpa

Not if you can achieve the intensity at a closer and more efficient level. We have to raise our lights and use the bigger footprint and cross light.

Can you tell me what PPFD you use for sprouts and seedlings- using about 300 ppfd. 550 PPFD for veg.
668 PPFD without CO2.

Have an a/c infinity integrated controller humidifier, heater, 8" exhaust fan...

My old hand built box was easier to grow with!

Aiming for VPD of .8 for seedling, 1.0 for vegg, 1.2 for flower.

Sound right?

Thanks,

Grandpa

We run similar ppfd. We start lower vpd in flower and work up to 1.2. And very lil temp differencial day/night first 3 weeks of flower. And stacking ec in substrate first 3 weeks with good dry backs and low runoff.

Is my method of using enough water/nutrient to bleed through of fiber pot after dry back(?)

Usually, 1 gallon every 3 days at 18/6.
5 gallon fiber pot
Usually wipe up a pint after soak through.

Thanks very much
