Hey anyone having trouble with ther DE fixtures?
I can put mine to 1150, but cant get past 650 or my tops shrivel and not want to grow?

Can you leave it at that height im guessing and raise up your plants with a small platform? I’m going in here blind what’s a DE fixture . ?

Double ended HPS. They're a lot hotter and brighter than single ended HPS and you need crazy high ceilings to use them, especially the 1000's. If you dont have at least 3 feet between the canopy and the lamps they're too close. My buddies hang 750's at 3'. 1000's are designed to light up a warehouse or greenhouse and be hung way up high.

Yea man , I've noticed been veging for 8 weeks which is long been experimenting with light height and wattage. And that's my conclusion my lights are at 650 for the moment watering tonight only first week of flower have about 5 feet of room will have to adjust depending on stretch hopefully after will have the 3 feet to push to 750 but quite positive will have to stay at 650

Yeah, I should add my buds that use them are also in sealed, Co2 enriched rooms which makes their intensity a bit more useful.

All good, I stay with the classic 1000w single ended bulbs. I trust them and am comfortable balancing rooms with them. DE presents a whole other set of challanges, but when they are in a dialed room with the proper ceiling, they're unreal. Even still a 750DE is about as much as I'd put into an indoor grow room. My buddies running gas just love them.

Also what's this green light green tops not much temp swing at night?

Depending on the plant, when going to multi light DE rooms (even vegging under 630's and SE 1k's) would have to turn the lights down to 600, then 750, then 1k over the course of 5 days. Enviro and light intensity sometimes throws them into down syndrome.
