Mephisto’s site says it will be back on line on 4/20

Pot size- 5 gallon fabric pots Medium- Pro mix with a 4-4-4 mixed in (40 gs each) but top dressed with a 2-8-4 10 days ago Lights- 2 HLG QB288 4000k V2 Water- PH’d at 6.5 Temps at top of plants- a constant 75 F

I top fed them a 2-8-4 10 days ago those edges showed up when I switched lights. Just figured it was light burn from how strong the new leds are. Still believe it’s a potassium def? If so how do you recommend to fix it?

They are most definitely showing better signs they haven’t been watered since last post and moved to the lights to 36’ away from the top of the plants at the time of the last post. I will say I also started to give them 4 hours of lights off time. I honestly can say Ive noticed that they start...

Thank you for the guidance! I greatly appreciate your reply!

I’ve built 4 QB288 V2 doubles each ran with a MeanWell XLG-240-M-AB and I’m looking to dim it since at 36” it’s to intense for my plants. Am I ok with wiring a 50k Ohm pot?

Ok I will lay off watering and raise the light Thanks for your help!

I’m having some issues with my autos. Watered yesterday with 6.5 ph dechlorinated water. Woke up to some looking like this. Only thing that has changed other then watering is I changed the light from a 8 bulb T5 to a 250watt LED. The light is hanging at 24” from the top of the plant. Other...

how far away from the plants do you recommend them to be? These lights are bright! A touch over 17,000 lux at 24" from the top of the plant

Received all my parts today and am currently putting together the lights. I must say I was intimidated by building LEDs but they are super easy to put together thanks to the video posted earlier. One thing i forgot was a dimmer and the hardware to mount the drivers. the boards came with...

I figured I would try these as hangers with YoYo rackets Cables Also I’ll need to start thinking about air filtration sooner rather then later...Does anyone have any input on filters or fans to use? Using the calculator on Phat Filter’s site I’ll need 275 cfm Not to sure if it will be setup...

Thank you so much for breaking that down in lame mans term I greatly appreciate it!

Understood. I personally love my bulk grains. But I to started with BRF.

I don't see why it wouldn't fit at roughly 600mm (23.6 inches) x 205mm (8.1 inches) Absolutely a LED noob here what do you mean by cap the wire individually? I'm assuming there's so sort of dimmer on the outside of the driver. Your setup is amazing I hope one day to have something like yours...

whats your plan of action? grain? brf?

Thank you so much for guiding down the right path! do you feel like heat will be an issue? My room stays at or below 70 year round. also since I plan on cycling these plants for a perpetual harvest will one of these lights be to much for a 2’x4’ space if I ever would like to downsize?

Good Vibes on your adventure! you picked a great one always enjoyed KSS
