    1. Myth Busting - Autoflowers Revegging (can autoflowers reveg? Give us your thoughts!)

    Come give us your thoughts; we want to hear from you!
  • We're looking for grower submissions for any autoflowers that they have had tested by a lab or using a home testing device. The idea is to create a grouping of tests that we can use a resource to show growers (both new and experienced) what kind of cannabinoids and terpenes some of the strains we're growing are testing out with!

    Appreciate any help and consideration! Click here for the thread!

Nothing.
With a 200-watt CFL lamp, average 1.5 to 2.0 oz (3.5 oz for advanced growers) using a 3.5 x 1.5 x 6.5 ft. grow cabinet
With a 250-watt HPS lamp, average 3.0 to 5.0 oz (9.0 oz for advanced growers) using a 3.5 x 1.5 x 6.5 ft. grow cabinet
With a 400-watt HPS lamp, average 4.5 to 9.0 oz (14 oz for advanced growers) in a 3.5 x 3.5 x 7 ft grow room
With a 600-watt HPS lamp, average 5.0 to 10 oz (21 for advanced growers) in a 4 x 4 x 8 ft grow room
With a 1000-watt HPS lamp, average 9.0 to 18 oz (36 for advanced growers) in a 5 x 5 x 8 ft grow room (with extra CO2 only)

This seems to be decent info. Could someone else credit this?


So many variables...

It's so many variables no one can tell you what can you expect.
I get 190g from my first grow using 250W HPS.
Then I get 70g from my first grow using 63W CXB3590.
Now I get 350g from my first grow using 200W COBs and I have still place for 1 or 2 plants in the tent so maybe 100-200g more.
