Is it absolutely necessary to flush your plants before harvest? I have several plants in my flower room that are at different stages of flowering. They all get fed from one res, so it will be a challenge to flush the the ones that are about to be harvested and not the others.

Thanks...

YES!!! make sure you flush your plants or else they will end up tasting nasty!

Flush them and only give them straight water 2 weeks before harvest.

flush for 2 weeks??? maybe u mean 2 days? sounds lil off, but who knows im baked

Anyone else with hydro experience have any input on this? Two weeks does seem like an aweful long time to flush for. Thats like 25% of the flowering time... lol

I am not sure about hydro myself, however either potroast or nongreenthumb both seem to be expert hydro growers here, try one of them. They are both extremely helpful too.

I also thought it was 2 weeks. But I just bought my hydro system today, and asked the store owner, and he said no,, only flush for one week. He said if you go longer, you plants will start to brown, and any shorter and you will get a bad taste.

I talked to him about growing tomatoes, and every question I asked he answered me for BUD...HAHAHA.. SMART MAN HE IS...

Peace, and hope your growing goes well...

haha!! all those guys know why people really come to their stores!! Thanks dude. One week sounds about right... THe time is approaching... Good luck with your tomatoes...

No!! No!!! Really.. I do have a tomatoe plant also.. hehehe But that is not the one I worry about.. It is just for snacking on when I get the munchies...

Remember,, this is my first hydro system.. and the only reason I bought it was because of the trouble I was haveing with my first grow with soil. BUT OH MAN>> it has only been 6 hours since I took my plants from soil to Hydro.. I washed the soil off carefully thinking I would kill most if not all my plants.. They did not wilt or anything so far,, amatter of fact they look so much better already.. the leafs that had rolled under like rams horns have already started comeing back and they look so much healthier.. I doubt if I will ever go back to soil.. But hey this is my first 6 hours.. Tomorrow you might hear me screaming BLOODY MURDER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

LOL! dude, i started with hydro right away. Never used soil ever. I always thought that hydro seemed easier and all the crap with nutes etc, just seemd like a pain in the ass. I have not really had any problems (knock on wood). I don't even have a ppm meter, lol! I will get one soon though. You shouldn't have problems. Just remember, easy on the nute solution while the plants are young or they will appear droopy. Thats pretty much the only issue I ever had. Ohh yeah, and pH. Keep it low like 5.3 to 5.8.
Let me take another hit....

I AM FALLING IN LOVE!!!!! If my Hydro system had curves, I would marry it...hahaha.. This thing is great. I washed all the soil from roots to replant in my hydro, and even today my plants look much better with more growth then before. I am going to look into getting a PPM meter. I wonder how much they cost?

Splifman, can you show some pictures of your plants and system?

Later, and good luck with the harvest. Sure hope it is some great bud.
