it shouldn't do them any harm to flush again, so long as it's just plain water, maybe wait 'til tomorrow so the plant can wick off some of the water you've just put in.
When you do it next literally put it in the bath and run the shower head (or garden/sink and use a hosepipe) through the medium for a good 5 mins so there is PLENTY of run off.
There is a great technique coined 'make it rain' basically you do regular heavy waters and the next time you feed, the plants use it a lot more efficiently and fully. Plus it helps to keep your soil PH in check and stops salt buildup which makes it really easy to flush at the end when harvesting and is generally good practice to keep the plants healthy
the cycle goes (when you see the plants need water) Water, heavy water, feed, and repeat. But in future wait till the soil is dry 1 inch down OR lift the pot and you can just tell by how heavy/light it is, heavy = needs no water, light = needs lots of water, in between... you get the gist
Iso and any real coarse salt, I prefer kosher or sea salt. It's pretty much like 420 cleaner, I'll use the daily use formula when I am being really lazy and have the extra cash though. Picked up a lot of tricks from the first smoke shop I worked for, that was one of them lol. Prior to that I was boiling my pipes. I've just been lazy I usually keep it super clean though. Thanks MB it hits like a dream and it's pretty unique I think, I like it and the buds too lol.
That sounds cool, a bong or what? Be sure to share the final product with us, that would be really cool.
I was going to make a bong first to get the basic wood turning down, treat the inside with linseed oil and leave to soak in for a day or so. And then a bubbler, seeing as I have a bong that'll last a while now, so it doesn't matter if I mess up the wooden bong XD need to get the lathe and the likes first
