  1. Hi ChewVin,

    Thanks for reaching out!

    The best time to fertilize your hydroponic plants is after you’ve changed the water in your system, i.e., for the most part, the rate at which you change your system’s water determines how often you’ll need to fertilize.

    Factors such as plant type & size, reservoir size, room temperature, etc., influence the rate at which you need to change your system’s water.

    A good rule of thumb is to fully change your water at least every 2-3 weeks (though this does largely depend on the aforementioned factors).

    However, you may find that you need to top up your reservoir levels before then. Do so intermittently, while keeping an eye on your pH and TDS levels.

    We have a dedicated article (Understanding pH for Hydroponics) to assist you with that.

    Hope this helps. All the best!

  4. Hi Roy,

    Thanks for reaching out to us!

    The joints between solar panels aren’t sealed. Technically, you could use sealant but that could void your warranty.

    Instead, you could use a damp-proof membrane. These are however visible from underneath – some may consider this to be an eye-sore.

    Purchasing some gypsum board to create a “false-ceiling” of sorts will offset this issue.

    In short, you’ll have a more water-tight structure that is still aesthetically appealing.

    I hope this helps.

    All the best!
