The ROI-E680 is the perfect balance
of size and performance for the
experienced hobbyist and professional
cultivators alike. The E680 is a more
portable and light weigh fixture
accommodating cultivation's with
modest space availability, tents,
vertical gardens and any commercial
application facilitating 4x4 canopies.
The ROI-E680 is a very powerful
fixture and a proven versatile workhorse in any garden, producing heavy yields
and high quality harvests. Growers Choice does recommend the E680 be used
with CO2 supplementation to promote a healthy cultivation and the largest
yield potential.Without using CO2 the grower may be introducing more light
than the plants can process, possibly causing stunted growth or light damage.
Know your garden and provide light accordingly.
