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.
