So I purchased all of the supplies I need for my container garden today (except the plants). Since this is an ER board, and we love to talk money, I'm going to share what this little project/hobby is costing us so far for 5 self-watering containers:
The containers:
2 - 18 gallon tubs (have 3, so only bought 2)
1 - 10' X 4" long piece of PVC pipe (will be cut into supports and wicks)
1 - 10' X 1" long piece of PVC pipe (for water entry)
The growing medium:
4 - 2.5 cu ft bags of Miracle Grow potting soil (may end up needing 1 more)
1 - bag of polymer moister crystals
1 - container of Osmocote fertilizer
1 - 2 cu ft bag of pine mulch
Total cost for the above, with tax: $109.58
So, about $22 for each container with medium. I will buy plants soon and add that cost.
Not bad, especially if this turns out to be a long-term hobby, b/c I won't have the "start up" costs for the containers every year.
Make sure you bought Miracle Grow Potting mix, not potting soil. With self-watering containers, I don't think you need the polymer moister crystals. As for the mulch, it is my understanding that pine mulch is slightly acidic. But since most vegetables strive in slightly acidic soil, I think it should be OK.
