The 35 gallon Under Current© Pro systems will function much like their 8 and 13 gallon counterparts, but will feature several unique and up-sized heavy-duty components. For commercial applications, the Under Current© Pro triumphs in efficiency and yields. The Pro system offers growers the opportunity to fill very large spaces and grow massive plants without the extra work of managing multiple systems and reservoirs. Having fewer larger systems equals higher productivity in terms of workflow, transplanting, maintenance and harvesting. The Under Current© Pro System would be best situated in either a greenhouse or indoors with a combination of vertical and horizontal lighting. The 35 gallon Pro growth module with single plant sites will be best utilized on 70 in + plant centers.
