anyone ever have gnat issues? i have had a great many flawless runs until the current grow. Gnat infestation that i just cannot get rid of resulting in the destruction of 3 trees.

What have you used in the past if you have had gnats in this media? close to running coco for the summer and go back to ppk after.

What is a 'ppk'?

Thanks

What up CO? ppk 2 cent definition is its a recirculating hydro system that reduces the perched water table that features wicking with recirculation, giving u several options to control watering frequency. air gap between wick/drain helps control the hydraulic effect making sure that if pump failure occurs or u r slightly under watering the plant can suck up what it needs. If the plant is staying to wet u can drop the water level giving a bigger air gap thus reducing the moisture level in the medium, along with ur pump watering options. If u have pump failure the wicking action can keep the plant alive for a longer period of time vs just rdwc does. Also no issues with water temps like in rdwc cause ur growing ur root mass in the pot, not in the water.

tip burn. can be caused by over ferting, too much air movement, or low humidity.

a little is common among us weed growers because we tend to push the plants too hard. it's mostly caused by high salt concentrations. i see it as a sign to back off on the nutes a little.

Appreciate the response. running about 58-65% rh untill mid flower then i start to lower to the 50's, then 40's later. What do think is to low of an rh during mid late flower??

I presume that leaf tips cannot be " repaired " by the the plant so all one can do is prevent the tips from continuing to work there way in? correct?

thanks... bsafe

in an ideal world using vpd principles straight up would be great for overall growth throughout the life of the plant but pandora opened that nasty little box and we have to live with the results.

so i think that 55% +/- 5% is a great compromise rh when factoring in pm and bud rot against yield in late flower.

higher in that range lights on and lower lights off. maybe a little below 50% depending on where you live because of spore count.

on the leaf tip question you cannot repair the damaged tip. but if it is prolific maybe you want to pop off the worst leaves just to make spotting a recurrence easier. or cut the tips off existing leaves to better observe emerging leaves for comparison.

i don't let a little tip burn concern me too much. depending on strain it will start around 1250 ppm at the .5 conversion. i usually steer the solution down by then anyway.

Thanks fellas,

that is exactly what it looked like, i thought i was having deficiencies at first and i couldn't control it. after a bit i decided to pull the plants to inspect roots but i didn't see anything on the roots, but there were lots of gnats on the surface. guess ill have to kill and start over.

Before you cull everything, consider the advice on this thread:

I was successful with orthene/Riptide. It's a trick figuring out how to flood a ppk system for a root soak but I got it done and I'm happy to report no root aphids or dead girls.

My Jack's nutes shipped yesterday; 4-20. How sweet is that? Hopefully that will be a good sign of things ahead.

have a ? about veg. Going to set 2 3g/40qt combos up for veg. Would it be better to run a 400mh vertical/horizontal or use 2 4' 4 light t5's and sandwich the plants?

The cheapest I have found the 3gal 40 qt combo is 20.00 shipped, sound about right

I've had great success running the 4' t5 banks. That being said, if you're growing trees, vertical lighting in veg is preferred. I'll be switching to vertical veg again soon.

BigNev,

If you don't mind me asking, where did you find the 3gal 40 at combo for $20.00 shipped? Thanks

that was on 6 each, bigger discount than buying 1's

gregor_mendel · Apr 26, 2015

I paid $18.39 per plant module shipped from GlobalIndustrial for 12.

RamCTD1027 · Apr 26, 2015

I have a 15' x 15' room and a 12 plant limit. I was planning to use the 70qt muck buckets with 7 gal feed dishes but now I'm starting to rethink that. Should I go with the 40qt buckets and smaller feed dish?

What do you guys recommend?

twist1uc · Apr 28, 2015

Hey D9,
I know you've posted this before somewhere. But, what timer are you using again?

THANKS!!!!

i got mine from greners. a nice little timer. easy to use.

twist1uc · Apr 28, 2015

Damn things are pricey. lol (I guess everything is when I am multiplying it by 3)

delta9nxs · Apr 28, 2015

you can run all three pumps off the single timer by using a relay.

or from the timer itself if they do not draw more than 15 amps together.

twist1uc · Apr 28, 2015

That was my initial thought. But doesn't each timer have to be set up specifically for the number of plant modules?

Probably the larger, but do you have a goal?
The smaller rig is good for plant up to about 1.5 pounds, the larger rig for about 3 pounds.
