Aero Spray System HELP!

He all.....Can someone offer some help? ....PLEASE!

Set-up:

(2) aeroponic systems (20gal) with 350gpm pump & 6 nozzles in each
(6) netpots in each container
(2) 12" airstones in each container

HPS 1400w for 15sqft
5.7-5.8 ph maintained
3 types.....mostly indica strain (Bubblegum, Aroura Indica, Chrystal ).
Nutes: change 1 time/week with GH Micro, Grow, and Bloom. Add Epsom Salts and Hygrozyme.

I see so many people talking about running 1200-1500ppm in these systems during flowering yet I can't go above 700ppm without the risk of nute burn. The room is well ventilated but I have no c02 generator and don't wanna spend big$$$ for a c02 meter or a c02 generator if I'm off base. Any ideas? PLEASE!

Can you explain why you think you risk nute burn at 700ppm? Also, what nutes are you using in bloom?

Im using a homemade aero setup.. my ppm is 650 and my plants are doing AWSOME!! PPM also relies on temp in the res and many other things..

got any pics of those bubble gums....i got some seeds bubble comin soon

also for a co2 solution... do a search...

basically you can take some high active yeast ( which can be found at any grocery store). 1/2 cup

Sugar 1/2 cup

And water. 2-3 cups depending on the size of the container

Put these 3 in a bottle.. shake it up real well and poke a hole at the top of the cap... this should generate a good ammount of co2 of a small room maybe 4x4x6 feet. should take like up to 6 hours before the ingredients interact chemically before you can see active co2 bubbles.

more suger + yeast + water the more co2

when you want more co2 just shake up the bottle.. and you will see the solution bubbling up.. ( this is co2)

Goodluck!

Aero is so much more efficient that you should always use a 50% nute load.

In my systems I always run fox farms starting around 800 then working my way up to about week 5 of flower your at about 1500-1550 then to induse late season flowering you taper back down to 1200 and then a flush.Each nute maker has a different concintration of mix to get to thier suggest ppm levels.They have differnt properties so gh might need not so strong because they use differnt feeds while Fox Farm has a different mixture makeup that needs more particles for more strength.Keep your water at 5.8 and follow the chart your nute maker supplies and it will tell you day to day within a week cycle where your ppm should be for that nute and if you stick to that your good and as you get comfortable you can learn how high you can go to improve yeilds..Good luck....FilthyFletch hope I helped

Thanks everyone....There is no question about nute burn above 700ppm using GH 3 part. It is evident in the leaves as well as the amount of nutes the plants use.

Thanks again.....Actually I've made a large C02 generator using exactly that.....yeast and sugar. I can't use a c02 generator that uses propane or nat gas and using the bottles with a timed dispenser becomes extremely expensive.

Bubblegum pix....

Thanks again to all.

Blonddie07.......sounds as if we're using similar systems (home made aero spray systems) and 650ppm is usually right on target for what they need/use. I've added some blossom blood in the latest mix and will be running @ 950ppm and keeping a close eye on them. I'll post when they're done!

I love the bubble gum plants.I actual grow from clone from the original motherplant that was used back in the day to create the plant now known as bubblegum great plants heavy producer huge nugs and fast flowering.I flower in 5 weeks with 10 days veg growing aero able to pull over 120 oz from 28 plants per round...FilthyFletch

nice looking plants

Do you have any pictures of your system inside? I'm curious what nozzles your using and which nozzle layout.
Beautiful plants, can't wait to see what size buds they'll produce

if your having trouble boosting PPMs, its usually an environmental variable thats lagging behind. Light, heat, ventatilation, water temp, and feeding need to be in balance for the plants to be able to use all the nutes available.
I start with heat, let it get a little warmer (not res temp)and see if the plants can/are starting to use more nutes

Thanks again..... As far as the nozzles I prefer (after trying many) the 360 degree pin sprayers. I bought them from a place called future garden and they're about 8 bucks for 5 of them. These sprayers are great for a few reasons: After drilling the hole in the pipe a rubber bushing is slipped in and then the nozzle is screwed in to the bushing. No need to tap the PVC manifold with threads. If they clog all I do is lift the top of the aero tub, reach in and pull the pin straight out, run the pump for 5 seconds to blow out the gunk, then push the pin back in and I'm off and running....no fuss, no muss, no nozzle replacement. I've made so many of these aero tupperware tubs I can't tell you. The one thing I strive for is to set it up in such a way that parts replacement (while system is up and running) is easily done. For example: I never glue the last fitting (where the manifold is connected to the pump) in case I need to do a quick pump replacement.
