An idea worth testing? Of Course - aerating soil water - my experience

Ok, to set this up. As most do, I feed, water, feed, water, etc. And on feed days, once in a while, time would limit me, and I would not always be able to siphon out all of the runoff. The next day, the saucers would be dry as a bone. That evolved into doing it on purpose with a measured amount (half way full).

So I decided one day to try a modified version of that. Problem one: standing water. Added a pump and a mist stone or three. I wanted to try a 2ft flexible misting tube, but those start around $10 a piece. However, had bought a 6-pack of mist stones and a few T joints for under $4. I figure the upward flow of bubbles would be enough to move the little amount of water sufficiently. I also positioned the bubblers right next to the holes in the planter bucket to help get some bubbles in the soil directly. The aerated water is a secondary delivery method for Oxygen. If you do research on aeroponics, you will find that many people agree that cannabis production potential is a balance between oxygen and nutrients. Hydroponics representing the heavy nute limited oxygen delivery while aeroponics focuses on high oxygen and limited nutes.

Side note - I keep my water in a 5 gal jug and keep the air running through it all the time to keep the water as saturated as possible.

Problem two: We all know runoff water is not necessarily the balanced mix we initially feed the plant. The ph is changed, the ppm changes, some nutes get used up quicker than others, some nutes stick to the soil better than others, some are soluble and others and not.
Fix: I simply top hand-fed my plants until the very first trickle of overflow. I let the plant/soil soak up and saturate. I start doing the same thing to my other two plants. Then going back to the first plant I fill the fresh mix of feed directly into the bucket. A slightly deeper bucket that I used to replace the over flow saucers. This way, fresh nute water is fed on top and from the bottom. The plant will soak up the "reservoir" over time. But now I can extend that time by a day or two.

Now, as I said, the days the plants are exposed to the nutrient rich water is increased. And naturally when I give the plants just straight water [and cal-mag], the overflow is diligently siphoned and I "till" the top half inch of soil to help promote evaporation.

All of these may seem like small additions. But isn't the simple fact that we give nutrients and have schedules and well managed environments evidence enough that we want to push our plants genetics to the maximum potential. And they all add up to a lot. Another measure I take is to move leaves into the optimal position to allow the most light penetration.

I thought to myself, why is soil better? Or, why is hydroponics better? Of course, some say soil "tastes" better. And almost all would agree that hydro produces more. Potency, however, is to much of an argument to use as one of my own. I wanted to combine the idea of increasing the plants' exposure to nutrients while maintaining proper nutrient delivery.

Also, keep in mind that my situation allows me to tend to the plants in this detail. I only have 4 plants going right now and this will last me about a half a year. I grow for personal only.

Anyway, here is a link to a video I uploaded which shows the idea. Now, the way my camera works, when I snap pics, it records a few seconds before, so you will not get any narrating. Instead, there is some info in the description and the comments.

In the comments, I wrote a short update on day 54 which was 3 days after video was taken.

Sorry for the long read. for those that get this far, thanks for listening. If anyone has any input, I make my decisions on how I grow based on many sources and deciding for myself which points I agree with, as a lot of people do to customize their grow to their needs and desires.

Update day 54 of flower - buckets are dry as a bone. Soil looks perfectly moist. No change in any of the leaves. I have at least one cola about 6-7 inches from a 400 watt hps bulb on full blast and there is no stress to be seen. I do have some leaves trying to aspirate more rapidly, but that is because my thermo was in an area that gave me mid temps. I have since moved it to an area that reads the hottest area the plants are exposed to, and 7 inches from the light it is 81deg.

Here is a minimally informational video of 3 days after the top/bottom delivery method.

Day 55 - Noticing hardy growth specifically in the mid and lower sections of the colas. Buds are swelling and new calyxes are growing. I know it is only opinion, but I see more growth last night than individual days past.

Edit: the reservoir bucket has been dry for one and a half days now. But the soil is still VERY moist with feed water. Took out the bubbler, will try this method again next nutrient feed round.

Here is the video of my grow area. I just started messing around with the editing, trying to start growing subscribers and doing more videos.

I am 1.5 weeks in and well over 1 foot of growth. In just 7 days, which is when I took the pics, I had 12 inches of growth and have refilled the reservoir with about 15 gallons of new nutrient water so far!

Here is a pic close up of the top of the plant. I compared it to the previous grow this plant was cloned from and the bud starts are equivalent to 5 days later - day 10 of the hybrid grow is the same as day 15 of the all soil grow. Of course, my methods in general have evolved, but so far the growth is strong and the top stems are fat!



I started the flower stage at 18" tall. I also grew each plant to have only 3 or 4 main branches and pinched off all new branches until day one of flower, from there i have only taken off two branches that grew in unfavorable locations (center beneath main canopy). I decided to focus all bud growth to only the top of the plant from the beginning. My pruning method may have attributed to the initial stretching. But, the top of the main stems seem to have decent spacing. So maybe the pruning style really did make a difference. But I will keep my mind open to other possibilities. Always learning.



Oh, Another thing could be that I used Fox Farms soil which was very high nitrogen content, even when cut the run off measured in at 1700ppm. I have flushed until the runoff was down to ~400ppm. This may be another contributing factor.



I am also refining my nutrient table and I may be stressing them a little this way too, though the new growth since I have been mixing flower nutrients and after the high nitrogen flush, has been tremendous. Excellent shape and color. Pretty much everything that is new growth since day one of flower has been the best results so far for me.
