The Oasesbox ideal for growing tomatoes plus other fruit vegetables and herbs. It is one of the best self watering planter (SWP), on the market.

I recommend that a grow bag is placed on three Oasesboxes to increase soil volume when growing tomatoes – especially salad and beefsteak varieties.

It is also very good for growing chilies, aubergines and cucumbers and other vegetables and herbs too, where high quality is required.

How does it work?

The Oasesbox for growing tomatoes is a reservoir container with a cone insert in which the plant grows, in whatever medium is chosen – usually soil.
When the reservoir is filled with water and nutrients, a plant is able to take up water and nutrients whenever needed.

Here is how the Oasesbox works in the video above.

One of the biggest problems with growing tomatoes, is that when the soil dries out, plants are unable to take up nutrients.
This results in Blossom End Rot and other problems associated with nutrient deficiency and stress.
Having a reservoir system avoids this problem because water and nutrients are available 24/7.

There are many benefits in using the Oasesbox self watering planter for growing tomatoes – here are just a few:

  • You don’t need to water everyday but your plants still receive all the water and nutrients they require 24/7.
  • Because plants are always kept happy with water and feed, they won’t become stressed and fall victim to disease and nutrient deficiencies. That means healthier plants, producing better quality and a greater yield of tomatoes.
  • One of the most helpful benefits is that you can go on holiday and know that your plants are still watered and fed.
  • Water and nutrients supplied 24/7 means less Blossom End Rot, less fruit cracking and splitting and a more consistent size of tomatoes to name just three benefits.

More Features and Benefits

  • It is very easy to clean and maintain – no capillary matting to change each season.

The Oasesbox Versus the Quadgrow Planter


  • The Oasesbox is very easy to set up.
  • Single units can be used or several slotted together in a straight, square or corner shape.
  • No capillary matting is needed.
  • It is easy to water the Oasesbox reservoir.
  • If a greater volume of soil is required, a grow bag may be placed on top of a set of three Oasesboxes which is a good idea when growing tomatoes.
  • A root disease cannot spread from plant to plant because each reservoir is self contained.
  • A wide surface area for roots to absorb oxygen.


  • The Oasesbox is slightly more expensive than the Quadgrow Planter.
  • The Quadgrow Planter has room for four plants.
  • The small soil capacity is not suitable for growing large tomato plants, unless growing hydroponically or semi hydroponically, so it is best to use a grow bag placed on top.
  • No water level indicator.

My thoughts on the Oasesbox

  • It is very easy to set up – put soil in the cone, water in the reservoir and off you go!
  • It is a very sturdy item.
  • There is no need for capillary matting which can struggle to take up enough water on a very hot day.
  • The roots sit in a cone that is slotted down into the reservoir so it is very reliable.
  • Roots are able to grow into the reservoir – important in high temperatures.
  • When growing tomatoes, the best results will be made when placing and grow bag on top of three Oasesesboxes for the extra soil capacity.

The Quadgrow Planter is a very good alternative.
