Hydro Nutes? I visited a huge Hydro grow op

awful funny stjimmy...commercial growers drip to waste all day everyday...there must be something to it...Zandor really wasn't condescending...he was just pointing out that It's a weed, you can grow it any way you want. I have never read a published book that advocated no changeout's...
It's funny too, every time this debate comes up, there is
always a guy that ends up saying...Just flush your nutes every week, what a waste...Grow the way you want. In the end no-one else cares, except you. I know I grow the way I want to. peace

you did manage to get more condescending without really addressing any of my opinions, so i guess you can be congratulated for that.

pretty obvious you never read cannabisworld or overgrow, and after this dumbassed reception i'm beginning to realize why none of them are posting here either.

but by all means, continue on with your jackassery, sir. flushing those nutes down the drain every week or so is just what the companies who make them want you to do.

Well it's your loss but happy growing anyway.

I read some are wondering how they can tell if a plant is lacking in a certain nute?
Read the chart I linked to in my post "You need this"

And, can't we all just get along? Sniff...

Just curious, if you guys were adding, say 3 gallons of nutes per day to a 12 gallon res. for 8 plants, would you still see the need to change them weekly, or is that enough change out?

i grow a sog similar to what zandor showed but with 18plants. My rez is a 50gal tote. The plants set down inside the top of the tote, and it can hold about 20 to 25gal. of nutes, and will feed the girls for about 3wks before the pump starts sucking air. I used to change the rez out every two or three wks, and also at the switch between veg and bloom. Some time ago i stopped changing out the nutes between veg and bloom. Then i stopped changing every 3 wks. Then i stopped changing between crops. Now i never change anything, ever. I set the ppm so that it slowly rises over those 3wks, and when its time to addback, its just plain tapwater. I never have noticed any nute deficiencies in either the veg or bloom cycle. About all i need to do is addback the water to the rez, and a little bit of nutes to bring the ppm back to where i want it, then we start all over again. As the water is used up, the ppm will slowly rise, and by the time the rez level gets low, the ppm is about as strong as i would want it to get, then we addback plain water, which drops the ppm, so i squirt in a little nute consentration to bring it back up again, and we start all over.

It takes a little practice to get it perfect, but i never dump expensive nutes anymore, which also pretty well ended any labor involved. You have to have a ph and ppm meter to do this tho.

I stopped changing nutes between crops, and i dont even clean and disinfect the system between crops for the past few yrs. In hot weather, i add a 1/4tsp of h2o2 per gal about every 2 weeks, and there has never been any root rot, pytheium, algae, or sickness in my crops, and i use Dyna gro products, which most "pros" wouldnt use if it was free, and zero additives, except from some h2o2 now and then.

Give it a try for yourself. Expermintation is the best way to see what works for you, and what wont. Good luck
