Havest Flush - DWC

Hi,

My plants are almost ready.

I was told that In DWC you only need to flush for 5 to 7 days. Well I started flushing 6 Days ago, but Now I'm thinking that the plants might need a few more days befor I havest maybe a week.

So I'm wonding how long can they go without Nutes in the water?

you should be just fine..... i can't imagine it being much different that a drip system. I flush using ph'd water for the last 2 weeks and the plants are fine..... usually at the end of the two weeks they start to look a bit starved, but that's ok....

Hmm.

The only Diffrance is that there would be no build up of solts in the meduim. or do you flush out your grow medum at the start of the two weeks and then give them plain water?

Thanks for your input.

I don't flush out the medium, but I don't have a big buildup either, I use rockwool, don't really know if that makes a difference....

I would think that you should be ok though..... I would just keep doing the water only and watch them, if they start dive bombing, then you got a problem, but I don't think you will, the plant should still have enough stored up to be ok for another week.

also, i only use the 4" cubes, not the mats......

Coola. Thanks.
