Adding top feed

  • Good morning everyone! So I spent the day installing and upgrading a new add-on for AFN that effects our vendor and breeder forums. It's the same setup that we are using on High of the Tiger, but we didn't realize it would effect members a bit differently here on how it's been received.

    The major benefit of the add-on is that it allows breeders/vendors a global calendar (that they add their own events to,) a group media gallery, group discussion area, an information/about tab, and a few other goodies that should make the experience overall a better one.

    One major caveat to point out, the new groups (where you see the overlay) unfortuantely *REQUIRE* you to join them in order to post in them. This is done by design of the software (and I understand why,) however it's been requested to see if we can circumvent this somehow. I will inquire to the developer to see if it's an option available or one that can be added to future versions. So to be clear, you MUST JOIN the group to be able to post and reply, even if your existing threads were there before. We apologize for this minor inconvenience but it's a one-time deal and then it's back to business :-)
  • Hey we're testing out our new Raffle/Giveaway software and wanted to invite you all to try it out with us for a chance to win a Smokin' Screws pipe screen!

    This will be for USA-based growers only (to start,) and the only requirements are 25 minimum post count to put in an entry (which you can do once per hour!)

I've recently decided to partially DIY a new, shorter, top feed dwc system to avoid plants' growing into the lights.
Most top feed build instructions include a submerged water pump that can add heat to a reservoir.
General Hydroponics has a different scheme that works very well, based on the concept of AIRLIFT, which effectively mixes air bubbles into water, thereby reducing its density.
The resulting "light-weight water" is easily spewed out of drip rings, etc.
The only electricity needed is the amount to run an air-stone type pump of just a few watts.
If anyone is interested, here's the cheap (around $9 before shipping) GH device that allows adding a top feed to an existing system:

And a video on how to add it to a bucket:

I'll be adding 4 of these to each of two 4-site (after drilling), 20 Gal (probably 15 usable Gal) Botanicare reservoirs with lids.
Multiple plants in a large reservoir are easier to maintain than several individual buckets.
