SO I ma looking at following Rex Grigg's dosing regime. I like the idea of making batches of ferts in water. The question is what to store them in.

I was thinking some of these:


Pre mix the 250 ml versions, then each morning.. shake, squirt out what I need into a measuring spoon and add to the tank. Quick, easy, no mess.

What do you guys think?

Personally, I just use micro measuring spoons and scoop the dry powder directly into the tank, because that just works for me... but if I were going to premix my ferts into solution, I would use one of these. Only $6 and no measuring spoon necessary!

^ But if you do that, don't mix your CSM+B into the mix. It will react with the macros, from what I understand. Don't take this as the gospel truth, but read up on it first before mixing all your dry ferts together!

I just keep mine in a small airtight rubbermaid container and dose them dry straight into the tank. No need to dilute and it takes about 3 seconds.

I use the dosing bottles, like Church recommended. For small doses it seems to be easier and more accurate.

I have used the ketchup dispensers from walmart (like in WarDaddy's first post) for quite a while. I used a spare measuring cylinder from one of my old ammonia test kits. Now I just do dry dosing (exactly as lego mention) and find it much easier without any side effects (haven't seen any yet).
