What is the ideal environment for roots, I have a hydro setup with a large reservoir underneath in which the water is cold, am I just nitpicking or if I buy an aquarium waterheater to keep it at a set temp will it keep my roots healthier and increase growth/yield? or does the temp need to vary depending on what stage your plants are at?
Thanks for that fellas, went and got a heater and set it to 68, I've posted some piccys on the grow journal do you think they look okay?
