Def go with Atleast a 400 watt. If space isn't an ISSUE go with a 1000 watt. The 150 watt is just to small in my opinion. Hope that helps.
he didn't ask if he should go with a higher wattage light.... do people even read posts anymore?
150 Watt will support 2 plants, beware though that you might have issues with it penetrating the lower canopy. So try to do LST or SCROG grow.
For my setup, i have 150 Watt HPS up top and a few CFL lights sitting at the bottom for the lower part of the plant
150 Watt is for 2 plants in a very small 2x2 type of area. Not something you want for 4 plants. Why? Because it will not penetrate to the lower leafs, that is unless you use CFLs along with the 150 Watt
they are one of the top notch system and last a long time..does anyone know if the sun system 150 hps is any good
and how many plants can it support can it grow 4 2 1/2 ft plants veg 2 months then flower?
i saw it at my hydro store and i want to get it because its 150 watt is it good
