I might have got a "bad" batch, dunno for sure, but I'm done with H'tron.
Got almost 50 pounds of that crap that I'll sell to the lowest bidder.

Use coco in your next netpot and see if that fixes it.
Worked very well for me and eliminated the need to keep the H'tron wet.
I got bucket, water, coco, 5" netpot, wicks, nutes and an airstone.
All my PH creep went away. 'cept for some dropping near the end.
And that tells me it's almost harvest day.
So I start to flush from the top.

You use coconut in your net pot? Would you net pot hold the coconut inside it? I have some coconut but I haven't used it since I repotted my first soil grow. I had given up using coconut since I have switched to hydro grow. I wonder if it is possible to post a pic showing how net pot could hold coconut inside... Do you use rockwool along with coconut inside your net pot?

Thanks...~ :thumbsup:
