Yes, follow the instructions on the back of the package.

Remember, that when you first introduce nutrirents to your plants, they should have their second set of real leaves and only use a QUARTER (1/4) strength nutrients the first time.

I would then do a reservoir change 7 days later (remember to top during this time), and then use 1/2 strength.. after you reservoir change from the half strength, start using full.

Its best to change your reservoir as often as possible... But you will need a lot of water and nutrients to do so.. Most people change their reservoir every 2 weeks.. But if you do you will have to watch out for algae.


About the pump, you leave it on for as long as it takes to flood your medium (what your growing it in). If it takes 11 minutes- So be it, You run the pump for 11 minutes, and how every many hours off. The faster the pump speed, the shorter the time will be for filling.
