@Galaktus It will work for a short amount of time but will definitely need more light to get a good yield
I have 4 such lamps
I have a tent 90 cm by 180 cm or 4 lamps enough I would like to put in it 8 plants auto what you think
I think I hate the metric system 
no idea how big that is.
1,63 =5 feet
They might be enough for one small plant
1 lamp has 4000 lumens
1 plant oh no😭
I was running three 300w leds in a 18"x 36" tent over one plant. Those leds are probably more blue which is good for vegging but not so good to flower with
I use 575 true LED watts in that size tent. My lumens are 36k. This is good for a one plant SCRoG … kinda “meh” for two plants…
Your lights will work good till about node 3-4 then you will need a more intense spectrum
thank you all for your help
