Hey bucket heads, here's a hack I made a couple years ago, I call it the "schnorkel": top feed without a submerged pump. I know, you don't really NEED top feed if your fluid level is high enough to keep the bubbles wetting your net cups, hydroton balls, and seedling plug. But I think it helps seedlings get started.

But more importantly, it's fun to say, fun and easy to build, improves grow efficiency by eliminating a pump motor, and makes something you're already doing (bubbles) perform an additional function. How growweedeasy is that?

From the bottom, take a 6 inch piece of 1/2 tubing, and slip it over the end of a 6 inch piece of 3/8 tubing BLACK tubing. Poke the top, skinny end up through your container's lid, sticking up just enough to attach an elbow (or a T if you want to feed 2 cups) and attach a long enough piece of 3/8 black tubing to point the trickle near the center of your net cup. I installed mine through the black lid from a Costco jar of nuts.

A 1/2 inch hole through the black plastic will form a tight enough seal around 3/8 black tubing to block out light. Can be used as a light tunnel for your clear air hose, keep the light out.

On the bottom end, either poke your air hose into the bottom end of the big tube, OR for a more secure connection, carefully cut a small hole in the side of the big tube about 2 inches from the bottom, just big enough for an air-hose elbow or other barbed connecter to poke through.

When the bottom of the big tube is down in the solution, and air is fed in, the bubbles will force the water in the tube up and out the top, feed your plant with richly oxygenated nutrient solution.

I don't do DWC but I just want to say you folks who do have my admiration. They are just lovely looking grows. Enjoy

Drekthar yes, I'll prune little bits here and there late into flower like that, but preferably you would want to make sure they've gotten their final thinning about 2 weeks if not 3 before chop.

I live in Canada's Northwest Territories where power is quite high so i'm doing photo periods for that reason to reduce electricity use. I did autoflower first and second grow they work ok but as mentioned the reason I switched after I got more familiar with things.

Very nice, I'm on my 3rd rdwc grow just starting . Trying auto flower , should be interesting. Hopefully not a waste of time

IslandColas do u think it too late to do a bit of "pruning"?

[Drekthar]

24" inside so 3" spacing on the grid.

[IslandColas]

I absolutely love this cycle. What size are your trellises?
