DIY Cold Air Intake for Air Pumps

Appreciate everyone weighing in here.

The thought of root rot wiping out a crop makes me rethink my desire to cut corners. Luckily (for my plants) it just started snowing again just now -- can enjoy cold outdoor air for a while longer. 🥶

Did some rough math to help determine cost/benefit and wanted to share in case anyone else is considering the upgrade:

Costs
  • 4x 100w chiller < $450 (CDN)
  • 400w/mth 24/7 = $27/mth ($0.929/kwh avg)
  • Maximum cost year one: $774
  • Maximum yearly cost for energy only: $324
Benefits
  • Water always stays within ideal range
  • Less stress to plants
  • Less maintenance (e.g. bottle swapping)
  • Decreased chance for root rot
  • Increased yields (as a result of above)
  • Less worry and anxiety overall
I didn't put a dollar figure on benefits, but I'm left feeling like it's worth more than $27 per month. Hell I would pay more for just the last bullet point.

"This ain't no cheap hobby" is bang on.
 
When I committed to growing, I knew that I wanted to learn to cultivate the absolutely best bud that I could. So when it was necessary to spend the money to dial in my grow room to the environment where I live, I did that instead of deciding not to grow Cannabis.

I believe you either do it right or you gamble with your bud quality--not to mention all of the time, energy (your own and the utility) and $ spent. No contest!!!
 
ocgreen, it does not show up well in the photo, but I wrapped the reservoir with bubble wrap (the large bubbles) to provide some insulation. You could use the smaller bubble wrap or foam packing material, but I would not use fiberglass because if it gets wet (spillage or what ever) it night retain the moisture for a longer time, spills just run off the bubble wrap.

Sounds like we started growing for same reasons. Not saying this first batch will be exceptional but I simply won't be content to produce anything but high quality long term.
 
I'm a "junior" now--in my 3rd year of growing. I haven't produced exceptional bud yet--it's been good, folks been happy--but I'm sure trying to get there. Each grow is full of lessons, and then I understand things so much better after I've learned the lesson. I'm inching my way closer to "exceptional bud".....
 
I think you may be selling yourself short. I remember reading through one of your logs and was impressed by the buds you were able to grow. Totally respect if you want to get even better but i would say you're no longer a junior/novice.
 
One of the driving reasons I grow in the winter,, And alltatup you are short changing your abilities, your advice and guidance have been spot on.

ocgreen RagWeedDWC I really appreciate your words!! I love to learn new things, and cultivating Cannabis has been a challenge--a real brain stimulant.

I'm happy with my learning curve. But I want to grow and cure the kind of bud where my weed buddies will hear the angels sing, their eyes will well up with tears from the sheer perfection of the high, it will take their breath away, they won't recognize themselves, and they will surf the tsumani-sized THC wave all the way to the shore.

Is that too much to ask for???
