I think I figured out what happened

I cleaned the Hydro Halo rings by soaking them in a mixture of Dr Bonner's pure soap + Arm & Hammer Washing Powder + H2O2

Although I rinsed them, apparently not enough, which would account for the bubbles and even though the rez pH was fine (6.0) the roots got soaked with washing powder residue

So the moral of the story, thoroughly rinse your HH rings

Hopefully, the footies over the pumps will prevent algae build up inside them

All 6 seedlings are pushing on 2"

Not sure how long to keep them under 24/0

I usually do this for a week then cut back 20/4 until they are ready to flip

Thoughts?

Lights

We're getting closer to very bright future with leds

COB emitters are game changers. Think mini hps, but with directional light (no reflected loss + much less heat)

See links below to a good example eshines 5G. Now it can be improved by replacing the multi-chips with COBs + a few other things, BUT...

It is user friendly. and simple to replace emitters- YEAH!

DIYers are proving that a combination of NW or CW @ ~15%, surrounded by WW *~50% 3000k + 50% 2700K) works quite nicely (amazing actually)

Cobs are more efficient than multi-chips, PLUS, being all one spectrum, their life expectancy is both greater while the light is uniform

Improvements would include:

* driver moved outboard to minimize heat
* Note emitter layout on 160 v 320. The 160 will provide more uniform coverage
* Daisy Chain
* 2 o/o switches one for the 4 outside emitters. This to be employed once fruit is established

Plants in vegetative stage do not need as much WW as they do once fruiting begins

Remote is an unnecessary expense

Since roots are already protruding outside the 1/2 size starter cube it was time to move to phase 2: the bubbler

I posted step-by-step pics so anyone can see how to do this.

To minimize root rot, I cut starter cubes in half, and water with a meat baster, or eye dropper.

Once the seedlings outgrow the plastic egg tray, they are moved into 3" net pots, 6 of which fits into a 4g tote

I combine small and medium size polished ornamental stones (Dollar Store) in the net pots. First I put a single layer of 'flat' stones on the bottom of the net pots, followed by the plant.

The rocks on the bottom forces the roots to grow sideways, which makes for a stronger anchor for the main stem. I then cup the plant and begin infilling with stones, being very careful not to hit the delicate stems

The stones keep the developing roots cool and allow any additional top feeding to quickly drain into the bubbler.I use a 15 liter per minute 4 head air pump + 4 large oxystones. Note the pic also has a 4" disc, which throws more air, BUT, it is too light, and floats. Figure out how to keep it on the bottom and it's an even better option

I keep the water line right at the bottom of the net pot until roots start exiting, then lower the water line

Nutrients

I like Hydroponic-Research V + B it is a one step powder. It works great, and I am not paying shipping cost for water, PLUS, I have an RO. Water comes out ~ 20ppm. At this stage I mix @ ~ 200ppms, and we're off

WOW nice setup PetFlora - Cant wait till mine get big enough to flip and watch these babys flower

[PetFlora]

Thanks Bud!

Wait until you see the F & D with High Performance Rez in action.

Shit, I missed the pic of the roots exiting the cube. The prior post pics is maxed out

So...

Is it possible to change this threads' title?

I have regained my sanity, or lost it...

Here is the elephant in the room that no one has considered

Don't confuse any R/B or multi-spectrum emitter first generation grow results with what will likely happen in subsequent generation seeds/clones, namely: genetic alterations, due to improper spectrums that are likely to negatively affect all subsequent seed generation

Genetic Predisposition

https://en.wikipedia.org/wiki/Genetic_predisposition

Plant and animal genetics will change/adapt due to environmental stresses- and rarely for the betterment

Human and animal predispositions include; heart disease, cancer, scurvy, hip dysplaysia, allergies... to name a few well known subsequent generation genetic alteration/health issues.

Unless the cause changes, predispositions are likely to develop

IMO, this is compounded because mj is a fruiting plant, therefor having a greater need for a balanced spectrum throughout it's life, although that balance is tilted toward blue spectrums in veg, and red in flower

Think how commercial fruit and vegetable agricultural practices of not replenishing the soil with proper macros or micro has impacted not only the taste, but the nutritional value of the foods we eat

At least 10 years ago, the Department of Agriculture stated that agricultural top soil (top 6") is dead

Nutrients is energy, and so is light

So whether I am growing with hot5s or leds, make mine predominantly WHITE

[PetFlora]

Surfin the net for where to buy cobs I came across this DIY thread

IMO no need for the regular bulbs as overheads, drop or side lighting maybe, but


Feast your eyes on this...

Anyone interested in buying/building an led panel/light should subscribe to www.ledmagazine.com

The current issue has awakened me to not buy any fixed diode/emitter lights at this time, and likely never

One article blows up the 50,000 hour life expectancy BS. It might be true, but not as a useful light to grow mj. There example shows the same light new v 5000 hours. 5000 divided by 15 (av hours per day between V & B)= 333 days. Nooooooooooooooo!

I am going to go with either a manufactured light where cobs are easily replaced by the owner, or a DIY using Molex receptacles + COBs; see my post # 37

hey pet flora

is this a silver skunk test grow or a clinic in led lighting?

just wondering?

[PetFlora]

Bit of both

As you know, not much going on at the moment, although the young leaf are reaching toward the lights

No real reason to post daily seedling pics

Pretty much all the lead up is out of the way
