Hps Bulbs
When should I start forcing my indoor tomatoes to flower?
The tomatoes are "bush boys" and I am using a 400W HPS
with a MH conversion bulb for veg. How long should I let them
veg under the MH and when should I switch to HPS and force
them to flower? This is my first grow with tomatoes indoors.
Thanks!
once the plants are about 1/3 the size that you want them to be. this is the case with almost all plants grown indoors.
