Hey man! I haven't personally grown hydroponically yet but I've been watching a lot of people grow on here. I have no idea your knowledge level. But you mentioned your having a hard time with heat. One method I see that works well is adding a frozen bottle of water to your reservoir sometimes a couple. @rolandr88 just did his first grow and used that method. growdiaries.com/diaries/145137-grow-journal-by-rolandr88
Anyway good luck! keep us updated!
