Frequently Asked Questions

What size of pot should I buy.   The medium (33cm) or large (45cm width)?

This all depends on what you want to grow.   The 33cm width pots have a capacity of 5 litres each.   This is plenty of space to grow all types of lettuces, herbs, strawberries and greens such as spinach.   

The 45cm width pots have a massive 15 litres capacity each.  This is ample space to grow all kinds of fruiting vegetables such as tomatoes, capsicum, zucchini and even watermelon if you really want!

Can I just stack them on the ground and start gardening?

Yes, certainly and most customers do!

Can I grow in soil too?

Yes, soil or soil-less growing medium such as coco peat, hydroton or perlite. The most optimal medium is an 80% coco / 20% perlite blend which we supply here

Do the Hydroponic systems require access to power?

Yes, or standard systems do. If power is not available, there are other options. Either solar powered pumps, or fertilizer injectors connected to standard water mains with batter operated timer. You can run an entire quarter acre farm from 4 x AA batteries! Check out this post for more info

With the hydroponic system, can I put regular seedlings in?

Yep!   With the Coco/perlite growing medium, you can simply put regular store bought soil grown seedlings or plant from seed.   

What is the running cost of the hydroponic systems?

Each Hydroponic systems comes with a 25w water pump.   For a drain to waste system, the water pump runs on average 20-30 min p/day only.   
A 25w appliance running 24/7 per day at standard electricity charges equates to approx 2-3 cents per day!   So yes, it’s very inexepensive on electricity.   If you’re concerned about ugly power cords, there’s all kinds of ways to hide them.  Some customers paint them the same colour as the wall etc…

Are the planters made from food safe material?

Yes!   Food Safe Polypropylene #5. Like what yogurt containers are made of except we use a lot more of it.

How does the drain to waste hydroponic process work.   Does it waste water/nutrient? 

For the hydrcoponic enthusiasts out there, a drain to waste set-up is quite a foreign concept.   Most hydroponic systems are closed, meaning the water is constantly recirculating.   For example the Smart Farm Tower Garden.  

Drain to waste system is perfect for large gardens where recirculation challenges exist.   They also work amazingly well!   The key is providing a small flush of water at regular intervals.   Just enough to saturate each pot, without significant run-off.  We provide instructions on how to do this. 

How do I raise them off the ground on a tower?

Purchase 19mm steel poles (curtin rods) and drive into the ground then place a 1″ PVC pipe over then stack your planters. The center hole on the 18″ diameter planters fits a 1″ PVC pipe perfectly. Raise them off the ground & rotate with a 1″ PVC coupling. It’s easy!

What growing medium do I use?

Use a good quality soil or for hydroponics we recommend coco peat  with 1/4 perlite for optimal growing conditions.   You can purchase these from our on-line store. 

How do I water?

Simply water the top pot!   Each stacky has drainage holes in the center and outer clovers which disperse water optimally to touch all the root systems on the way down.   Otherwise called a flow through design they are designed to prevent root rot and disease. 

How much water should I provide?

When you see the bottom dripping, this means the above layers are saturated and you can let Mr. Stacky do the rest!  As a general rule set the timer to feed 3 times a day for example 9am, 1pm, 5pm at 3 to 4 minute intervals.   You can not over water but you can waste nutrients. Adjust watering settings as desired. When the growing medium is dry and your plants could use a drink then water them.

Is hydroponics really complicated?

No, it’s really simple!   To make it easy, we’re just adding nutrient to the water and then watering your plants with it.  With soil the fertilizer is already in the soil.  The liquid food is circulated directly to the roots enabling the most prolific, robust and vibrant plant growth with maximum yields.  As everything is automated, it takes all the guessing out and saves your plants from your unintentional neglect!  

Where can I send pictures?

We love seeing your pictures and we know you love showing them off too!    Visit our facebook page to post something or send us an email. 

How do I set-up my own automatic watering system

You will need a timer, submersible pump, tubing, and a water reservoir. Structural materials will include PVC pipe and steel poling.

How high can I stack the planters?

As long as you have a support through the middle, you can stack them as high as you want!.  We recommend 5 stacks high to ensure even water to each stack, but check out this photo   🙂
