First DWC

Thanks, Dutch. I've always wanted to do Hydro, so for my first time I got clones to ease the learning curve a bit. Eventualy I'll go back to autos so that I can share a perpetual canna garden with a vertical veggie tower in the same tent.

You say pythium was a problem throughout the grow; what was the temp of the reservoir, how often did you change the nutrients and which beneficials were used? Edit: I see it's 81F; that's a bit high, 10 degrees too much. I'm not buying a chiller to grow weeds, not happening. I'm considering a hybrid system, Kratky and DWC. Main differences are the amount of air roots, more air roots are required like a Kratky, I'm considering dropping the water level 6" below the netpot and keeping it there. I'll continue with a bubbler, everything else stays the same including the nutrient changes. This will take a larger reservoir than a 5 gal, I'll use 12 gal buckets or maybe totes.

You go this growmie!

Happy Growing, Buddy! 🌱🌱🌱

Better than expected, given the root rot. Lights were actually 300 watt. Too bad the MKU didnt survive. Next up, a 3 plant recirculating drip system, with the res outside the tent, and hypochlorous acid every feed

I now have all of my parts. Decided not to go with dwc as the nutes temps were an issue and I battled root rot the whole time. So, drip and drain to res. Advice given was 2 drip emitters per plant Running constantly thru daylight hours, and a few minutes per hour during dark.

After a few days, flush water is clear, and the plants were looking pretty hagred. Buds are dense and frosty. Removed most of the foliage and cut her down to dry. I don't want to estimate but I am guessing 1 oz or so. After dry, sweat and cure I will post the results. Drying conditions *24° to 25° 48 to 53 rH

Lots of shiny trichomes, smells delicious. Day 2 fresh flush. Yesterday's flush water was pretty brown. Again, UCRoots, and FloraKleen and pH to 5.9. The smaller leaves are losing colour fast, I might have to chop a few days earlier than planned, we will see.

I am collecting parts for a 3 plant system with reservoir outside. 😀 This should help with nute temperature. I am hoping it can be a hybrid system, timed drip with a dwc component, almost a bubbleponic. All depends on how low I need to place the res for good drainage, the buckets are raised 9 inches so the drainage will clear the port. More parts to get...

These roots are still sick despite the CCRoots and microbes. I have to shell out for a chiller before my next grow. Despite her rootzone, she it enjoying a burst of flower growth. I committed to flowering 10 weeks at least, so I just have to keep her alive. Had the temps, rH, and VPD in the zone, but suddenly there is a spike in humidity. Will upload photos soon.

Kept topping up res, did not use koolbloom. Complete Res change today. Began "overdrive" Continuing with hypochlorous acid and enzymes. I think these will be permanently in my base nutes from now on. 2ish weeks before flush, chop in about 3 weeks. Picked up some grove bags to try, got a cheap moisture meter for that purpose. I will compare jaring and grovebags, but the hydroguys say they really work. We'll see. Installed a Bluetooth thermo-hygrometer to monitor rH without opening the tent. Works, but hard to connect to unless I am in front of the tent. Good thing is it calculates VPD so I can begin trying to tweak that.

About 4ish weeks until harvest. She got a top up of fresh nutes, I finished the tiny bottle of bigbud, and don't want to buy more untill next crop. Res change coming up tomorrow or the next day. After that, the next change she is supposed to start Overdrive, I don't want to start too early. I have a very old bag of koolbloom dry, if it dissolves then maybe I will use some of that in lieu of bigbud. If not....😶 .

4 more weeks of flowering. Despite several near-death battles of root rot, she is flowering nicely. I am certain that she lost time and size with the disruptions. I will try to grow the same next time to measure my improvements.

Busy week in the garden lost one plant. Root Rot spread to other plant. Trimmed roots, gave peroxide soak, rinse, into clean bucket with fresh nutes. Included extra enzymes and microbes. Ran Ozone for a half hour to disinfect tent and aerial plant parts Addressed nutrient temp with AC air pointed to air pump and side of bucket. Gave Optic Foliar to help with the stress and root loss.

Lighting schedule got all messed up with the disease tent modifications. I am sure the plant does not like it. Works out to be very long day. 12 hour night resumes tonight. Fingers crossed she doesn't herm. I guess this may delay flowering...

End of week 5. 12/12 begins now. Happy budding, girls!

They are thirsty girls! Topped up with 2l nutes each, with some peroxide for good measure. The Kratky lettuces drank all of their nute so they were filled up as well . A leaf fell off, so my wife and I had a little taste.

Whatever I do in hydro shows up almost immediately compared to soil. Things can be tweaked and I see right away if the plant likes it or not. Soil took days to show, and days to remedy.

Day 6 and once again pH creeped up. Topped up with water, a bit of nutes, and corrected pH to roughly 6. The drip ring makes a significant difference, I think I will install one on the MKU next week.
