How often the pump runs has nothing whatsoever to do with how quickly a volume of water will heat or cool. Yes a pump running full time adds heat but that is minimal compared to the ambient temperature. Your ice pack will cool it down faster but it will heat up faster and you won't gain anything.

Evaporation of a smaller volume will also cause your PPM to fluctuate more than necessary.

But hey you have to live with it so do what you want. You always ignore good advice anyway.

Sounds like deflection to me. When said advice comes from pontificators (like when you said unequivocally that my issue was the stones) who have never actually done it, yes, I do tend to ignore it, but long before you decided to drop your, ahem, 'wisdom' I am/will keep an eye on it

Call me a pontificator if you like. I know what I'm talking about when it comes to the science behind water.

I and others have watched you troll this forum for years now. We have given you honest and helpful advice over and over and you throw it in our faces. So this will be my last post ever to attempt to help you.

Keep growing crap weed and enjoy.

@ RockinRobot , your describing basic thermal transfer,
and key point is res size to heat generated. Plus PPM always fluctuates.
PetFlora I think has a post stating he uses a fine timer to keep run times shorter , due to heat .. solved.

I have been following this thread and doing a drip over soil to get auto watering going on based on what I have learned here.
I'm about ready to get the 12vdc online for next phase.
So I took what I have and did math .. looks like 2 second time on for 27 periods a day to get me 1 gal/day/bucket.

That has been what I have gathered from this round of studies.
Please keep the bickering to a minimal , class is still on right?

Thanks DD. Hard to find pics of his grows, but I did, and he does knows things, it's just that he doesn't know EVERYTHING, but thinks he does

I hope he honors that he is done 'helping' me

I test cut a feed/drain hole in the 5g tote. The hole saw is slightly larger diameter than it needs to be:there's a slow drip. Either the inside gasket hole is too big or the outside diameter is too small

Going to hardware store to see what I can find

The 4 remaining girls are growing quite well considering that initially they weren't getting sufficient spray

A bit hard to see but there are tons of root hairs on the many fish bones (lateral roots)

I am having leak issues with the new ActiveAqua fittings. First the 1 1/4" hole saw from Harbor Freight is slightly oversized. I managed to fill the discrepancy up with silicone. New hole saw purchased, but it's too long for my mandrel.

Borrowed my neighbors, but the shaft is 1/2", had to borrow his drill, which is a beast. It had so much torque, and his fatigued bit snapped as the saw bit into the plastic. The hole saw tore across the tote, causing a few holes that I patched. Testing for drips, should be good to set up 2 totes this morning

Water drawn, getting ready to mix nutes

Pics later

[PetFlora]

wow, a lot more cleaning/prep involved than I remembered

Recleaned the; stones, square net pots, the mortar tub underneath (in case of spills). I connected the 730 gph bottom draw pump. Time to test (water only). Dumb ass me, I forgot to open the shutoff valves and blew about a gallon of water, on the tent floor. lol.

Adding nutes diluted to < 1EC/500ppm; pH 6.2

Sadly, the ActiveAquas didn’t do what I was hoping (at least not as configured). They are designed for flooding tables, not horizontal filling. I may need to close off half of the slots closest to the bulkhead in order to increase pressure of the spray/DO. These I’ll leave as is, but will adjust for the 2 smaller ones, whose roots do not yet reach into the net pots inside the totes, so still in the lpa

These are under the SPYDR 600 10 hours a day for a couple weeks, then 12ish

Flooding every 1.5 hours for a couple days, then increase pauses

[PetFlora]

Did anybody hear a loud CRASH?

DAMMIT

My table was off balance, causing the totes to tilt and crash into the rez. The good news is the plants are OK, but both bulkheads snapped- they're hard plastic

Just finished wet vacing the nutes (no, the mortar tub did not catch any).

I cobbled it together, one new Active Aqua and one old style. Those bulkheads are nylon

Made fresh nutes, and away we go

I've been challenged on whether plants secrete waste products through their roots, well, I came across it today thumbing through Indoor Marijuana Horticulture Bible

The solution transported through the vascular bundles or veins have many functions. The solution delivers nutrients and carries away waste products

There's only one place to carry/move them to, and that is down the main stalk and into the roots for elimination
