I just got my GroBucket in the mail. So today I will be showing you the unboxing and my GroBucket setup. I have 2 pepper plants and a tomato plant ready to transplant and set outside.

GroBucket Setup

So even though I knew I had to provide my own buckets somehow I expected the box to be bigger. But the most important thing is everything that was supposed to be in the box was there.

Setup really could not be easier. The first thing you need to do is drill the drain hole in your buckets. They need to be 3 1/2 inches from the bottom and they recommend drilling a 5/16 inch hole.

The hole can be a bit larger or smaller but the height is critical. Too low and your reservoir won’t hold enough water and too high and your bucket will be overfilled. It really needs to be just below the top of the GroBucket insert to work right.

If for some reason you don’t have a drill you can poke a hole in the bucket with a knife and then rotate it around to make it round but try for a 5/16 hole if you can.

Put the insert in your bucket and insert the feed tube into it. Make sure it fits snugly because you don’t want it to come loose when you fill the bucket.

GroBucket Soil Choices

The best choice for your GroBucket is coco but you can use any potting soil. Make sure it can compress well and it will work better if it doesn’t have perlite or other fillers because they will impede the wicking action you want.

Coco really is the best choice for GroBucket soil because it has higher wicking qualities than peat based potting soils. It also can hold more air even when wet than peat and it does not compress as much.

If you are thinking about adding garden soil don’t. It will not only compact and get hard but it also may contain pests.

GroBucket Setup Packing coco around the GroBucket insert

Here you can see the coco being packed around the GroBucket insert. You want to pack the soil down so that it is pretty firm.  There is a slight lip on the bottom of the insert to keep the soil out of the reservoir.

The coco coir will wick water from the reservoir and capillary action will move it up in the bucket. So it is important not to have large air spaces below the top of the insert.

If you want to add soil amendments like worm castings I would add them to the soil above the insert where roots will get quicker access to it.

GroBucket transplants

Transplanting Into Your GroBucket

Here are my plants set in their grow buckets. Add soil gradually and test the height of your transplants inside the bucket.

Add enough soil to place the bottom of your transplant on top of the soil and decide how deep they should go. You will want to leave the soil level a couple of inches below the top of the bucket.

If you grow your own tomato plants or buy transplants that are leggy you can bury the stems and plant deeper. The stems will root after a while. Otherwise, the top layer of your transplants should be set about an inch below the soil line.

So you don’t want to fill your GroBucket all the way to the top. Later you can add mulch to the top to help conserve moisture.

How I Like To Transplant

I like to fill my buckets to the level I want. If your mix is moist you can make a hole with your hand or you can take the pot your plant is in and press it into the soil.

It will make a perfect sized hole for your plant. Then remove your plant from its pot and drop it in the hole. Perfect fit and all you need to do now is firm the soil around it to eliminate air pockets.

Final Thoughts On The GroBucket Setup

The GroBucket setup was very easy to fill with coco coir. It is very easy to set transplants in the loose coco or potting mix.

It is raining outside today so I will be putting these outdoors tomorrow. I will water them in until the reservoirs are full and a bit of water comes out of the drain hole.

The first week you will want to water from the top to settle your soil and help feed the roots until they get established.

The beauty of the GroBucket system is how easy it is to water correctly. There is no guessing and your plants will thrive in them.

Here is the follow up to this article where the plants are set out and I share how I feed them.
