rhodes68answered grow question 5 years ago The 1000 is a 150 watt QB.
It depends on how big they get as its an area dependency.
As long as things are contained within less than 3x3 ... Yes
I run a TS1000 and a 600w HID, but I wont turn on the HID until things get big enough to be outside the Mars light pattern.
You might want to hedge your bets and keep one of the old leds hanging.
The old 30 watts of LED per square foot is not a bad guide but really does not reflect the new QB lights they are just better..
