150W HPS for Tomato Plant
My local hydro store has a sale on Sun System 150W HPS lamps ($30) and I was thinking of getting 4. If I arranged them in a square pattern, would that be enough light for a 3 foot tall determinate tomato plant? Would the bottom not be getting enough lumens? I would think keeping the lights a foot away from the top of the plant would keep it from getting too warm.
Or, should I just go for a 400W for a little more? ($150) |
i would think a 150 watt is not enough. i did ok with a 400 watt for 3 foot plants.now i have a 1000 watt light w/ 4 plants under them almost 4 ft high.

The main issue with tomatoes indoors is the vertical nature of the plants. This makes it difficult with any light source. If you find a way to trellis horizontally or get bush variety tomatoes it will help greatly. I once did a SCROG type grow with Roma tomatoes under a 345W LED light that produced about 20 2-3oz fruits per plant.
