Can O2Grow Replace Pumps and Stones?
- Thread starter PetFlora
- Start date
Here's a set up I plan to use once the babies are ready to move

Long overdue update:
Had a few setbacks with the white cubes as they either hold too much water or dry out to fast. Trial and Error
3 seeds are now seedlings (YEAH)
I combined 4 air stones 24/7 plus a 160 gph pump on a timer 2 minutes on/50 minutes off, with pump tube inserted into a plastic bottle that has holes in it, partially filled with a combination of platonic solids and small marbles: this to simulate water rushing down a stream that enriches the water/nutes with enhanced oxygen

I know, right?
Pics from when I could. Seems like another lifetime

OK a few pictures
The plastic soda bottle needs a bit more experimentation as to how many holes and hole size, as well as pump gph. This over soaks the net pots and I am fearful to soak the strter cubes and get root rot yet again.
I will try my small ~ 60 gph pump again as I need a bit more space to put blue ice pack in this 3 gallon tote with the ~ 6xs physically larger pump
The larger pump causes too much water pressure inside the bottle, which spits long streams of nutes out the sides of the the lid and into the igloo, so I drilled 3 larger holes but I think I can do better, or it would be better in a deeper tote, which could work similar to the pseudo LPA aero without constant clogged mist heads: Such is life when experimenting
On a positive note, all 3 babies are growing with roots exiting all net pots. The color adjustments did not allow me to get accurate green: leafs are normal green. Fingers crossed

The yellow lid makes it difficult to get accurate colors. The roots are nice and white and the plants are a proper shade of green

what a difference in just 7 days
update on my new technique for starting seedlings, and probably clones (see previous post of bottle) with platonic solids, which imitates the DO effects of a running stream= energizes the nute solution
Still dialing in the o/o times. Once I hit the mark the leafs should be reaching for the light
Obviously when the roots are lifted out of the nutes, they cling together, oh, and the yellow lid causes the root pics to look off, but they are snow white

CAUTION:
When I added the plastic bottle I put holes all around (360*s) which meant a lot of solution was splashing up onto the underside of the lid which eventually caused the starter cubes to get soaked, leading to droopy plants (and light tan roots), all because I took too long to replace it with one where the holes were on one side, which I could rotate aiming the holes directly into the solution
Yesterday I made a h2o2 solution and soaked the roots for about an hour, making sure to get h2o2 up into the starter cubes. White roots now. Plants look a little bit better today, and should be 100 later in the day

I rememebr reading about thes e o2 grow emitters a while ago, from none other than Heath Robinson, who reckoned they would emit too much o2 and turn the plants toxic.
the other thing is-Cal me cynical, but if they worked, surely everyone would be using them- they aren't.

Well, first, the O2Grow has a built in 30 minute on time then shuts off (I think for 4 hours)
The O2G is kind of expensive, which is one deterrent, and as I have discovered (they don't tell you this) it must be used with plants that have an established root system
The corner has been turned
1/3 has s pretty decent amount of new roots and is growing again
1/3 has a few new roots and is beginning to look better
3/3 is lagging behind
Pictures taken Friday 2 are much improved today. The plant roots pictured has roughly 4xs as many roots

if I want more DO in solution than can be delivered via airstones and an air pump, I am going to get a used medical oxygen concentrator off craigslist for $50 and simply run 90-95% pure O2 through my airstones instead of spending beaucoup $ on any O2grow product. But that's just me.
Sound idea. Do you have access to O2 canisters and proper metering devices?
Keep us posted
