Hey Guys,

Lets say one has a perpetual harvest system,

- there is a staggered harvest in a flowering room. Eg 8 pots, 4 plants 30days into flower, 4 plants 60 days into flower.

When it comes time to 'flush nutes' for the plants on 60 days so that the leaves go yellow and all the nasty nutes get flushed from the plants, how to do this without it affecting the plants only 30days into flowering?

All pots are hooked up on the same hydro system.

Does stopping nutes and feeding the plants NOTHING but water 2 weeks before harvest really make a huge difference in the end result?

Since it's a flowering room, you might consider using nutrients with 0 nitrogen.

If you did this, I believe it would be OK to nute right up to harvest, maybe finishing with a simple 24-48 hour flush, and have no horrible N taste.

That's why we flush, to remove that chemical taste, caused mainly from Nitrogen.

SUPERJJ85.........i just read your first indoor grow and it was exciting just to read it, me being on my first grow. I think next time i will start with a lot of seeds instead of doing them onesy twosy. I fanally got some Northern lights and wt widow in the veg state but i don't know the sex yet. Both are about 6 inches. I'm also thinking about LST just like you did. I've got a little time to think about it.Does anyone know if its worth it to buy the feminized seeds from seed banks ? Are the percentages much better ?

Honestly, I consider the number of seeds I germinated (and therefore the amount of plants I grew) as a newbie mistake. For the amount of light and space that I had, I think 6-8 plants would have been much more practical, and I could have achieved similar yields. Luckily they were all bagseed, so I didn't really waste anything but soil (and time, LSTing 18 plants ).

If you're using good genetics, that's yet another reason to grow fewer plants larger. Even moreso with feminized (more expensive) seeds. Yes you'll have a better chance of females with feminized seeds, provided you have your growing environment well in check, but it's still not a gurantee. I personally would rather buy normal seeds, grow a few, chuck the males and then clone the females for generations until I'm tired of them and want to try something new.

Good luck!

Please try to stay on topic pearl threads can become fragmented, and if so it makes it harder for people following in our proverbial footsteps to find the information they're after quickly

Back to the topic of "Perpetual harvest systems.. how to flush nutes?" then

I would have to have them on a seperate res One lot would still need PK booster, and the other lot might need a flushing agent, at the same time

Without a seperate res, it could get complicated IMO. You could remove the almost ready plants from the system, and hand water them

sorry about changing the subject for a minute.....you're right it takes away from the thread.

I'm not sure where exactly I saw it but I followed a thread about LST and in that case the grower took the plant to the bathtub and flushed it out there a few times...This method may work for you. There is something I'm not sure of....whether the nutes take some time to get out of the plants system or if you flush the surroundings and that does it ?

I'm sure someone knows the reasoning for flushing. It seems to me if salt builds up inside the plant then it would take some time and the bathtub might not due it [maybe w/many trips]. If you just need to flush the surrounding then the tub should be fine.

Two things often get confused regarding flushing

Flushing - at the end of flowering is also called Leeching. done to encourage the plant to use up all it's stored nutrients, and improve taste A week or two of real low EC should do it, some people use flushing/leeching agents (final flush etc,)

Flushing after nute burn, to remove excess salts - like intensive care

you should just split your system so the one stage is on its own water system..and same for the other stage

then flushing is no prob...neither is pushing your plants...a 3 week plant into flowering should not be getting the same strength nutes as a 6 week plant

Also...if you pump quits....you only risk damage or death to half your room
