ok have this new hydro unit with 16 plants top feed with 70% perlite 15% coco and 15% clay pellets i have an aquarium heater on lowest setting but still has the nut. solution at about 78 degrees is this too high?........i took out the heater and will see how low the temps go
Wait, what?!?!? Sorry guys, but where in the hell are you getting these numbers? 20-25 degres? Not F I hope! And you have a heater in your rez and the water is already up to 78 and ya think that is too low of a temp??? Wow - please, use the search feature and read all you can.
it is at 78 F with the heater..........wondering if its too high? its set at the lowest possible...... im running the light 24 hours a day and the unit 15 minutes every 2 hours...... if i shut the heater off i was afraid it would go too low........ill find out tomm how much lower it will go
Sorry to go off topic, but I was told to only turn on my hydro unit 2-3 times per day for about 30 minutes each time. You water this often? What should I do for 12 plants?
68 is the optimal res temp for hydro. Any more decreases the amount of DO (dissolved oxygen) and affects nutrient uptake.
