Hi guys built a 4 tub rack for my bps and I'm placing 1 foot of 11" flexwattper tub. The question is can I do a Parallel installation like in this site suggests?http://www.herpcenter.com/wiring-heat-tape.html . I will be using this thermostat http://www.amazon.com/Hydrofarm-MTPR.../dp/B000NZZG3S . Can I use only one plug for all 4 11"flexwatt tapes?
