along with the heatmat make sure you get the thermostat that will control it.

Roottech wasn't real bad just seems to take a lil longer. Was using some stuff that came with my original system and it worked better than roottech but cant remember the name of it.

RR's are no doubt better than RW. I show roots 2-3 days faster with RR's over RW and bunches of roots not just 1 or 2.
