Seedling Update: 2 are 1.5" tall, the others not broken through yet

Flowering Plant: I have been slowly reducing ec as she nears the end > 60% red hairs

Dropped to 700 (~ 1.2),> 600 and today 500(1 ec)

[PetFlora]

Had to drop ec from 540 back down to 500 (1 ec) this morning

Who says LEDs don't penetrate? The bottom portion is 40" below the light

I dropped seeds 11 days ago. 7 unknown strains from cali dispensary in water with a touch of sea 90 minerals. All 7 cracked, BUT, so far, only 3 sprouted Sigh

Anyway, they've been in the kitchen window, which doesn't get a ton of light, so I set up my DIY bubble bath (4 air stones+ large pump) and put them into coco net pot liners (soaked in veg nutes @ ~ 185; pH 5.7) which were inserted into 3" net pots

Light is T5 leds: 3@ 6500 + one 3000

Nutrients NPK Raw + a splash of Emerald Harvest CaMg@ total ~ 185ppm. Lessons learned from last grow will be applied

Once the roots get established I plan to move them into a lpa set up

Checking finishing plant this morning, the cube came apart and the entire plant fell over during the night

Nutes in the bottom tent cover. Phew, nutes did not make it to the floor, but will use my small cement mixing tubs from now on.

I planned on making a fresh veg solution (more N) < 350 as the leaves have lost most of their chlorophyll and there's ~ 10 days left

Fortunately, no snapped branches

Babies: none of the seeds popped, so I dropped more seeds directly into the coco pellets

[PetFlora]

Babies update: 3 solid citizens, plus, 2 more broke ground since moving them from window to the t5s

Damn the sat is taking her sweet time. Now ~ 2.5 months in flower with maybe 5-7 more days

[PetFlora]

5 babies

The ones in the front are older, and close to a red bulb which make the them look pale

[PetFlora]

Had to change lights over the babies this morning

My 8 bulb Quantum BadBoy went 'click' this morning: 2/4 bulbs went dark

Rather than mess with it, I decided to put my Amare Technologies SE 220 (CoB Hybrid) back into service

This is actually better as the BB needed to be kept so close that I could not rotate ice bottles to keep rez cool

Last grow was far from great, due to pilot error of mixing amendments into NPK RAWs already complete Grow/Bloom dry formulas. No doubt some them did not like hydro

Yesterday I checked root development. 5 plants total. Plants ar growing great, but some roots were only coming out the bottom of the net pots, while others were growing out the sides and bottoms. WTF?

So today, after watching NPK YT Microbes video, I had an idea

I mixed a very small amount of RAW veg Microbes loaded a syringe and squirted directly onto the coco pellets that already have young plants growing in them. Hopefully, this will promote more roots developing near the main stalk, without affecting the nutrient bath.

One dose should do it, to be repeated when I switch to NPK Bloom nutes, using their Bloom Microbes

There's an interesting conversation on another thread about DO

So, I've been thinking and searching YT for DO generators

Cheapest I've seen that looks like it will work: cost $175, but how to measure the effect?

I googled Dissolved Oxygen Meters finding they range from ~ $150>

https://www.amazon.com/Milwaukee-Eco...K5EJR5TPHQNGAS

Are they worth it?

I already have a 4 outlet air pump (used in my baby crib to start seedlings/clones), which may or may not provide more DO than what I am currently using in my grow room rez (igloo cooler), a 260 gph lp side flow pump (water exits down low on one side). I have a venturi attached to the top exit, significantly enhancing DO. This set up is on a deep cycle timer 4 minutes on/ 30 minutes off. I do rotate blue ice packs, but quite often rez temp exceeds 74*s. I'm thinking the place to start (for me) is a DO meter, then I can more accurately dial in the pump o/o times. Anybody?

Assuming controlling DO raises final weight by as little as 5 grams/plant, even with one plant over 3 grows pretty much pays for it.

Anybody know of cheaper DO meters?

No wonder my seedlings leafs are greenish yellow.

I just checked pH: it was over 7.5!

damn, I adjusted it a couple days ago, too

Stay vigilant my friends
