Reducing Algae build up in and around your Tower Garden

We are often asked about Algae.  Algae is a naturally occurring organism which is a result of exposing water containing minerals to sunlight. It isn’t harmful in small amounts.  So what can you do to reduce algae? The best method is prevention. If you keep sunlight out of the Tower Garden, i.e. keep the lids closed and all openings sealed, you can prevent algae from growing. You can remove Algae in the system with a brush or a hydrogen peroxide (3ml of 3% H2O2 per gallon of solution) solution. If there are particles floating in the nutrient solution, be sure to empty and flush the reservoir and growing chamber with ample water, and then start with a new batch of nutrient water. However, if the problem is severe, make sure you have the algae completely flushed out to avoid the risk of clogging some of the drip holes in the system.

Reducing Algae Between Pots

Algae can form between the white pots for a couple of reasons.  First, the pots are not correctly seated and therefore lacking a proper seal.  If this is the case you need to try and push them a little closer together.  If your Tower is already growing with some pretty large plants just tighten the wing nuts a little more and make a note to push down firmly on the center feeder tube next time you take it apart to give it a good clean.  Occasionally you will still get a little mineral build up here due to water resting on the lip.  Just take an old toothbrush, scrub sponge or small scrub brush once a week and give it a little clean.  As long as you do it regularly it will be easy to remove and won’t get out of hand!

Reducing Algae inside empty Net Pots

2″ Neoprene inserts can be slipped inside the netpot to stop sunlight getting into the Tower, reacting with the water and causing algae inside the Tower Garden.
