I'm getting a handle on Vapor Pressure Deficit using the SensorPush HTP.xw sensor and WIFI Gateway.

What do you all think about the Atreum Hydra 3200 4x2 grow light? It has 4 bars so it has good coverage even when close to the canopy. CCFC discount code (10%) knocks price down to $377.10 which puts it in the same ballpark (tent) as the SP3000.

Apple Betty would be gr8!

75 year old American lighting company, Dazor Lighting Technology gets into the Bar LED grow light game with the Parmax 4 and Parmax 8. Bluetooth mesh control is available. These bars don't need to use individual 660nm and 730nm LEDs for the Emerson Effect. They use horticultural tuned Lumiled...

I assumed the Grodan Macro Plugs were designed to drop into the hole in the top of my six inch Grodan Hugo block of rockwool. I should have checked the fit before I germinated my seeds in Macro Plugs. I know the plant looks strange - it is a co-joined mutant.

I'd go to horticulturelightinggroup.com and buy one of their DIY Quantum board kits. You build the frame to hold the parts and connect the wires. I think RUI10 is a discount code at HLG.

@Feijao How did you turn off these LEDs? With a power switch or with the dimmer pot?

good enough for veg but not for flower. not enough watts/sq.ft. 200watts/12sq.ft=16.7w/sq.ft. flower needs about 30 watts/sq.ft of light.

Taukealugs SPL-3 is good for quick disconnect AC power cord splicing.

HLG-120H-20AB should do the job. cost $48.75 at Mouser

cc is constant current driver while cv is the constant voltage driver type. Would you be happy with a wifi (no bluetooth) dimmer? The Bluefish controller does 0-10 volts and PWM.

1.The HLG-120H-54B driver can not be dimmed below 10% due to it's construction. 3.You need the Coralux 10v analog converter to use with the HLG-120H-54B.

The ebay seller recommends using a constant current driver. I suggest wiring all four red boosters in series with the HLG 80H-C700B .

Buy a 4x4 kit from Cutter

Pacific Light Concepts photo boost strips. Great spectrum with proven grow results on youtube Good build video

I'm not a Bluefish user. I'd buy 3 break-out boards so you can use all six channels. Put 5 Inventronics on each channels 1-5 and 2 on channel 6. May get lucky and be able to run 27 drivers off just two channels; I don't know Inventronics dimmer specs.

The wifi Bluefish LED controller will work with 5v and 10v PWM and 0-10v dimming and is available from a USA store.
