Ok, ill keep that in mind. Just for fun i might experiment with mediumless seed starting. Ill root it in paper towel until it has decent root, then sandwich it in split neoprene puck with root poking out bottom, throw it in bubble cloner. At that point it can live the next few weeks in the...

Yeah, the root riot cubes were super convenient, obviously i just got them too wet. So when you use the root riots, do you get a lot of roots coming out of them before moving to hydroton? When you do move them to hydroton, are you starting out right away with nutes 2 inches below pot? Or do you...

Thats my plan. Once they get bigger they are going into 15 gallon totes all linked with control bucket. Checking ph, ppm, filling, draining will all happen from the control bucket. My totes have a hole cut in lid the size of bucket, i have buckets that i cut the top 2 inches off of to fit...

So just rinse all the medium off?

Yep, i actually ordered blue tubing a while ago, still waiting. For lids i cut donuts of white peel and stick vinyl. Kinda funny though, i started with only one and did a temp test. White lid only dropped res temp maybe 0.3 degree from the rest.

I agree 100% on the plugs. Ive had nutes about half inch to an inch below pot since roots left the net pot, but for the first 10 days or so i had it up higher and the plug was soggy the whole time. I suspected the same about the rotted stem so last night i carefully supported the plant while...

Water maybe half inch below pot. GH flora 3 part (grow, bloom, micro) plus calmag and hydrogaurd.

Hello everyone! New to this site, recently joined since im getting back into growing. About 10 years ago i had a perpetual dwc setup going for about 3 years straight. Yeilds werent great (average maybe 1/2g per watt), but i never once lost a plant or had an issue like this. I was using...

Wow, did you have quite a lot of water volume for soaking, or just enough to cover the hydroton? Mine have also finally stabilized but i think my plants may have been further along by now if the hydroton was proper ph in the first place. I did stay on top of it and ph of solution was never above...

No top feeding here, but i have water level about an inch up the net pot. They are young seedlings. First roots reaching outside net pot today.

Yep, all same here, gh nutes and rising ph in the hydroton only. Out of curiosity, which brand of hydroton? Mine is "grow!t", ordered on amazon. Looks maybe cheaper than Stuff i used years ago. Rather than mostly nice round balls, its more irregularly shaped. I will say its getting better. Been...

I would agree, but remember im comparing it to the leftover 2gal in my res which has stayed dead on 5.8 with no adjustment. Only difference is no hydroton touching that 2 gal. Edit: oh i see what you mean, neutral hydroton pulling it to neutral. But is "neutral" and "inert" really the same? I...

It takes a pretty small amount. About 10 drops to go from 6.5 to 5.8 in about 2 gallons. Checked this morning and its still drifting but getting better. It was at 6.25.

Interesting, that probably would have corrected the issue im having. Im curious, where did you read that? Instructions on a hydroton bag or somewhere else? Most others are suggesting that it is inert and should have no effect on ph, but it sounds like it tends to be basic.

Original post was 10 years ago. I bumped with a reply because im having same issue and im comparing to same nute batch left over in res without hydroton. Check out the post before yours.

Same is happening to me and i have a separate res to prove it. Mixed up 10 gallons of nutes for my young plants 2 days ago. Ph'd it, let it settle for a couple hours, dead on 5.8. Used about 8 gallons of it to start 4 new 3.5gal dwc buckets, left the remaining 2gal in my mixing barrel to use as...
