Would the z2 be capable of growing 2 cannabis plants in a 3x3 grow tent?

  • Hi. Would the z2 be capable of growing 2 cannabis plants in a 3x3 grow tent?
    Thanks Sean

  • It depends on what strain you are growing, how large your pots are, and if you are training you're bending, tying and training your plants to occupy more space.

    We have compared the Z2 to the Z5, both lamps hung alone in a 3x3' tent and each illuminating two plants. The plants looked great in both tents, but the plants in the tent where the Z2 was hanging were not as thick. When we weighted the yield and compared the two setups, we saw that the Z5 yielded just shy of twice as much as the Z2.

    When growing plants indoors with lamps, photosynthesis is most likely limited by the availability of light. Adding more light will result in greater yields (up to a certain point). The Z5 performs decently in a 3x3' tent but will have less than ideal light intensity in the outer edges. It performs very well in a 2x2' tent, as a smaller total area will confine the light photons and create a higher average intensity.
    The Z5 draws 112w and covers 4 sqft with great intensity (24x24)
    The Z2 draws 50w and covers 2 sqft with great intensity (17x17
    )

    To summarize.
    Yes, the Z2 can illuminate two plants in a 3x3' tent, but it's not optimal.
    If you are growing small plants/varieties, in small pots, placed close together, it could give OK results.
    For a 3x3' tent, we recommend the Z5. Especially if you are growing medium to large plants and want to maximize the yield. If you're growing very large plants or plan to grow more than two plants in the future, we recommend two Z5 lamps.

    Are you familiar with light intensity measured in PPFD (┬Ámol/m2/s)?
    We have measured both of our lamps inside a 3x3' large reflective space and made detailed maps that display how they perform.
    Here is a comparison:
