I use 3 spikes per gallon lily container per month in the growing season. Hubs just snagged a 50 count pkg at DG for $2. I count 54 in the pkg.

I get mine on Amazon - a box of 40 pairs for $37. These are the kind Sea_shell mentioned: adhesive toe warmers that stick on your socks. I go through one or two pair a day from now through April.

The way I looked at the reviews 3 being above average 4 being good 5 being best..it looks to me as it has better likes than dislikes, on Amazon. For a dollar I think it would be worth a try. And if the wires do loosen up a bit my husband is a good handyman who has had to fix more expensive items that were highly recommended such as a Food Saver model that we had about 8 months that went caput, and would have cost more to send it back to the factory, we had only used it maybe four or five times....I use a hand operated model now that would only break down if I did. LOL!!! So for a dollar? Yeah, I will try it...think it would be great for pasta, veggies, blanching veggies in summer, even if I used it just one summer season for blanching veggies before canning.

Su, I think you set up is wonderful ! Plants look beautiful !!!! And I love the three hanging baskets also!!!!! Dollar Tree/yard sales/thrift stores are all great possibilities for reservoir containers! Yay!!!! Speaking of reservoirs,,,I am experimenting with 2 Kcups with fresh cut leaves. I have put them right away on wicks. I usually put them in a snack baggie with a couple inches of soil, set on its short end. They do well, and then when I transplant and put them on their wick,,,,,well,, let's just say I have an extensive cemetery. sigh,,,RIP. SO,,,we are going to START on wicks. We'll see what happens with a little more consistency. I don't have room to "dome" everything after they come out of the baggies. And I am not transplanting when they are too little. But when you grow in a controlled "womb" and are thrust into the cold cruel world, well,,,, sigh. Anyway,,,I am all for recycling!!!! Rosie PS. We have been going to Fish Fry every Friday and I save my plastic glass and my cole slaw condiment cup/lid and YEP I take them home with me! Now multiply that by 3 (me, husband, grandson) then multiply that by 6 days of fish fries and WOW!!! AND if I go out to eat and they serve me in plastic,, well, yep! Same rules apply, they come home with me!!! Lots of containers!!!!! I can use them and better than ending up in the landfill !!!! Useful things!!!! Yay!!!!!
