Outdoor Growing
1

Hi MacGyver and Latewood,
My main chamber has been harvested except for 2 Sativa dominant plants requiring 1 more week until harvesting. What impact on the plants would happen if I were to change over to Metal Halide and 18/6 lighting for the last week?
My next harvest clones are out growing the veg chambers.

One of the plants harvesred is Roberts Gold Leaf.

The plants would think that you were re-vegging, and stop producing.You could raise the light photo period to 14/10 and add your clones. I only use 16 hours of light when I veg.

It is also a fact that you grow a stronger root zone at 14/10 than any6 other photo period. The longer the lights are on, the less root mass is developed. (food for thought) Peace
