Super Hot Peppers and Grow Bags

In my earlier post I noted that I was planning to try out grow bags for my peppers this year. The reasons for testing this route are as follows:

  • I would like to bring the healthiest of my peppers indoors to over-winter.
  • Our soil quality is very poor, and improving it too much over the years may prove problematic as on our roof we need to keep soil weight down. With grow bags I can focus application of manure and compost in a very constrained area and limit the long term addition of weight.
  • Once it’s clear which plants are strongest I can adjust placement to maximize light, heat etc to those that will best deliver against those inputs.

When I wrote the earlier post I was looking at Vivosun grow bags (Canadian grow bag link here), and specifically the 5 gallon size. After some additional reading I’ve changed direction, at least for my first purchase. Yesterday I received my shipment of 9 Bekith 3 gallon grow bags (Canadian link to the Belkin grow bags here). I chose to go slightly smaller as several sources suggested that 3 gallons would be sufficient for first year peppers, and to limit the expense to fill all the bags with quality potting soil, manure and compost (at least the compost’s free as we have 2 Worm Factory 360 composters on our roof (Canadian link to the Worm Factory 360 composter here).

While I haven’t yet filled the bags (I’ll do so when the peppers are ready to transplant directly into them) I can say that they appear to be of decent quality. I’m hoping to get 3 or 4 years out of them, and given thickness and apparent construction quality I can see that happening. I’ll be curious to see how water permeable they are, and as a result how much more frequently I may have to water them.

I can’t wait for temperatures to get a bit higher and more consistent so I can get this rolling.

 

Testing Fabric Grow Bags To Focus Soil Quality For Super Hot Peppers and Tomatoes

As written in earlier posts the “soil” in our rooftop garden is miserable, made up of sand, lava rock and who-knows-what else presumably to keep it light given the volume up there. I’ve had reasonable success growing in this medium with limited use of compost / worm castings and fertilizer, but my compost bin is limited and the soil volume is substantial.

This year I’m considering fabric grow pots / bags (Amazon Canada has Vivosun grow bags here) for some of the more demanding produce so I can supplement the soil more deliberately through the season, and recover that soil at year’s end rather than have to remember where supplementation occurred for the next year.

From what I’ve read, the 5 gallon fabric grow bags should do for my needs, in particular for use with some of my super hot peppers. I’ll continue to grow most of them in the main planters, but intend to use 3 or for grow bags for comparison this season. I’m assuming the 5 gallon size would suffice for tomatoes as well, and so I’ll likely consider a comparison there as well.

If anyone has any experience using these I’d love to hear about it. I’m particularly curious how well they stand up to weather… can you really expect to get 5 to 7 seasons out of a single bag?
