Mr. Stacky Smart Farm Review
Mr. Stakcy Smart Farm is a much-touted hydroponic vertical planter. Mr. Stakcy is a leading vendor of a variety of gardening solutions like vertical stackable planters, hydroponic gardens, and garden supplies, and its Smart Farm is a super cool choice for you to grow multiple plants in a small footprint in your backyard or on a balcony or patio.
It is a 20-plant garden with an automatic hydroponic watering system for your living spaces. You need to fill the bottom water tank once every two or three weeks. The water pump in the tank will keep the roots of the plants wet so that they can survive for weeks, and you can even go on a vacation with no worry of underwatering.
With five stackable layers of four plant pods each, it can grow 20 plants at a time, and the planter will take up only a small room on your balcony or courtyard. The water tank underneath is a 16-gallon unit, and it features a 250 GPH submersible pump to distribute the water and nutrients to the plant roots.
Compared to a soil-based vertical tower garden, this Smart Farm is an easy-to-use, plug-and-play planter.
Moreover, as you know, plant growth in a hydroponic garden is many times faster than in a soil planter. So, you can get a good quantity of yields in a limited period of time.
This Mr. Stakcy garden features a size of 18.5 x 18.5 x 49 inches, and you can place it anywhere around your home. If you have a grow lighting system, it is also fine for indoor use.
The hydroponic garden comes with all the required accessories and garden supplies, like starting plant food, pipes, tubes, adapters, water heads, a 7-day digital timer, and more.

Greenstalk 5-Tier Original Vertical Planter Review
GreenStalk sells a number of vertical planters, along with garden bundles, bases, covers, and other garden supplies. Here, we have the brand’s 5-tired original vertical planter, which the brand also has on sale with different layers.
It is a unique backyard planter that makes you grow plants in the actual soil. With five layers of six planting pockets each, you can grow 30 plants in the system that you can place in your backyard, giving it an enchanting look.
Being a soil-based gardening system doesn’t mean that you need to water each plant separately. No worries. The GardenStalk system comes with a cool built-in drip-watering solution for trouble-free watering.
It has a water reservoir at the top that can supply water to the watering disks at the center of each layer. The disks distribute the water to all of the planting pockets to prolong the life of your plants.
You can simply set up the garden planter in your backyard right out of the box. Keep in mind that you should use the best mix of potting soil to make sure that your plants give you the best yield. The GreenStalk planter comes with 10-inch-deep plant pockets, so you can grow both large and small plants quite comfortably.
The planter has a size of 19 x 55 inches, and it takes up only a tiny footprint in your yard. It can hold 5 cubic feet of soil, and the planted and watered vertical planter weighs around 150 lbs. You need to buy the Mover Base separately to smoothly turn the grower to get sunlight for all the plants around the rounded vertical planter.

Garden Tower 2 Review
Garden Tower 2 is the epitome of home gardening. Apart from being a mere platform for growing plants, it also acts as a kitchen composter. The Garden Tower project has an integrated composter that lets you decompose kitchen scraps in an organic way and use the resultant vermicompost to nourish the plants.
Garden Tower 2 is the latest variant of the project, which first hit stores in a Kickstarter campaign back in 2012. The latest iteration of the vertical garden touts a number of features, including a 360-degree rotation to ensure sunlight around the planter, increased vermicomposting performance, and more.
Garden Tower 2 is a 50-plant, soil-based gardening system. The lovely thing is that you get it with a composter in which you can pour in bio-degradable kitchen waste for the process of vermicomposting.
The plants around the planter are thus lucky enough to have an amazing source of organic manure, and you get a chance to dump some of your kitchen scraps in an organic way.
Often Asked Questions
What Soil to Use in Mr. Stacky?
Mr. Stakcy is a stackable hydroponic gardening system, which means it grows plants in water-fed inert growing mediums in pots stacked one on top of the other.
You can use coco peat and regular soil to grow plants in the inbuilt pots, but the most recommended medium is a combination of coco peat and perlite for better and healthier growth of the plants.
Can You Grow Pepper and Lettuce in Mr. Stacky?
Yes, you can grow a wide range of vegetables, greens, and fruits in the Mr. Stakcy hydroponic garden system.
It is proven that peppers and lettuce grow perfectly well in stackable gardens like Mr. Stakcy, GreenStalk, and Garden Tower 2.
What Grows the Best in a GreenStalk Planter?
The GreenStalk planter is a soil-based hydroponic planter, so you can grow any common home garden plants in the categories of greens, vegetables, fruits, and flowers in its plant pods.
Make sure you choose more bushy plants because it is a stacked planter, and only then can plants grow in harmony around the planter. And the richly grown, well-suited plants can also add extra charm to the planter.
Can You Use a GreenStalk Indoors?
The soil-based hydropic planters like the GreenStalk, Mr. Stakcy, and Tower Garden 2 are basically meant for outdoor use, but they are also a good fit for use on balconies and patios.
I don’t think it is a great choice indoors because of reasons like possible water seepage, soil exposure, and the lack of enough sunlight for the plants to flourish.
Meanwhile, fully automated and self-watering smart hydroponics gardens like the AeroGardens and Click and Grows can be ideal choices for indoor use.
They can grow your plants, though in limited numbers, even in the darkest corner of your indoor space, thanks to their built-in LED grow lights and cutting-edge watering solutions.
