plasma light are just a sheer crazy idea ............super heated plasma over plants in a building
hell t5s are just gas with a arc of energy tho it to excite the gas so it moves causing light ........we all know how warm that gets
sunlight is sunlight ........it depends on the time of year /where u are / what kind of area u are in 150k lumen at noon no clouds 100k lumen in shade/cloudy days ............outside has more variables in growing them most ppl account for so it can fail easily
the Cheap LED lights do work somewhat OK ......if u are adding them into the flowering tent as a 2ndary light ...........the cheap 30 bucks ones lucky if u get 2 weeks to a month ...the 150-200 buck 300ws are not to bad
apollo 300w always did well (good growth branching nice in flowering too)
i really like these

they let me tweak the light waves .......a true all in one light for growing including a finishing mode if u set it yourself ....and it allows u too plus program in time settings
spent months looking at all the lights on the market this is the only one i found with this choice along with daisy chain control (2 plus lights all synced by one controler)
i got 2 of them 600w ..........order from them they are MAKERS so the price point differs greatly just turn on scpirts to the page u will see a pop up contact .....feel free to msg them
