Ya I believe it reacts with the nutes. I’ve tested a res at 2ppm after nutes added and it shows 0ppm. Maybe the chlorine is still active but I’m thinking not. I tried it. Not very successful. YMMV.

Add the Cl first. N will neutralize it.

907 Bluejeans Couple twofers. I’ll let them do what they do.

You will want your room temp higher than 20. Especially if you run led. Your pathogens are most likely in your water. I have not found the silver bullet. But sterile treatments or benny's is the go to.

Ya bro. I measure light. Just a cheep Lux meter but it gives good reference. I think I was at 15000 or so. May have just increased to fast. They quit praying Probly was in combination with overwatering. Thanks for your genuine concern.

Chockalope. Tossed a couple in the flower room today. May veg these for a few more days. They don’t want to show sex. Had a bit too much light on them, stalled out and quit drinking. Had to dial back the light and let them dry out. Seem to be back on track. A couple have some pretty good stank...

If you successfully calibrate your pen with 4 and 7 and your solution isn't old you should be good. It can go bad. I use drops for a second test if I think it's needed.

Next round you could always put a cut off plastic cup, sunk a bit around the base of the plant deflecting spray so it keeps the bottom of the stock dry. That root picknlooks great. I can’t see any harm filling from the top. As your thinking more 02 with the top watering.

If you can find a good used air to air heat exchanger it will recycle some of your lost heat to the fresh air commimg in. I use a temp+RH controller on the air to air and the same on the dehu. If it’s cold in the room the dehu runs. If warm the air to air runs. I bring in outsid air so it can...

5 Vintage blueberry 2boys in the group. Chockalope.

Chocolope a couple weeks ago. Also have 5 out of 15 Vintage blueberry make it above ground. Notified AK about the issues. Said I’d Ak know how they pan out. Most sprouted and stalled. Replacement may not be nessesary. Said he had fresh beans in the making. Picks to come.

Yes most have a thermal fuse inside the motor.

If you need to cool as well as lower RH use ac. If you need to heat and lower RH use dehu. As it generates heat. You shouldnt need to run both. One or the other. You could use a temperature coltroller to do the switching back and forth like an inkbird.

Flood and drain back to res works fine with coco. I did a greenhouse grow. Used a 25 gal res 3 plants 3 gal containers. Ran 400 ppm. All grow. Mind you it was hot and dry like 110f hot. Dumped the last few gallons out of the res and refilled. Took about 4 or so days to drain new res. Ppm stayed...

Sorry i should have included if your "ppm" is rising.you can let it rise to a point. But after that point you will run into over fertilizing issues.

A little something new I have been dabbling with. I guess you would call it HPA. Probly has a bit too many larger droplets to be true HPA but it is what it is for now. I’m just running the small res. Pump and 4 misters. Currently it mists for 0.3 seconds every 5 min. So far so good. Roots are...

You must have one of the older versions? The 2 part you can’t really tell there is anything in the water. Dissolves totally with a bit of stirring.

If rising your feeding to much or you have root problems.

Dep motors have stop switches built in. You need 24V DC power supply, a double pole double throw relay to switch the dc from +- to -+. And a timer. Or you can spend big bucks on a already built one.

Im just starting hpa. In experimemtal stage yet. What i am testing is poping seeds or clones in rockwool. I cut 1x1x3" plugs out of a rockwool bat to clone or start seed in. When roots start to show i put a small 1/4" layer of poly fill between the 2" net cup and the rockwool think pillow...
