Thanks again.
I have 17.5% stuff and got some on my hands. That bleached them for a while!
I run it once a week (on tank change out day)with rain water to just keep things clean. I believe this is especially important due to my higher than recommended tank temperatures and stray plant material...
Cheers guys. They were most likely advising me not to as pot is an expensive plant and I don't bother telling them what I grow. Although its safe to use, its probably not the norm for paranoid potheads to use any products that didn't come from the grow shop.

I have found somebody selling H202 on ebay and its 35% and half the price of the hydro shop. Hydro shop stuff is 17.5%. So it works out 1/4 of the price due to being double strength and half the cost.
Now I sent him a message for him to confirm that it is food grade and contains no stabilisers...
Cheers for the comments.
Toasty - Still using 3 a day. Not sure what is best.
They are in 3" rockwool and then in LECA (expanded clay). I don't want to drown them but equally want to give them enough of the good stuff...

Have you thought about creating a manifold using hose or 1/2" irrigation tubing. Then tap off next to each plant using 1/4" barb then 1/4" line to a 'T' piece. Then use 1/4" soaker hose around in the loop?

I find leaf shape within Chinenses can be different too. From plump tear drops to even more elongated. From lots of small leaves to less large.
