Harvest a Pound Every Three Weeks!

Cheers Lions bro yeh i think you might be onto something with the changing of the res more often, i been using a reasonably smal res and it makes me need to "top up" the res with fresh water to bring the TDS back to the desired level which in turn MUST be affecting it i thought because maybe the plant is using more of one nute type than the other? ? I might start changing the res more often! Does the plant use more or less nutrients at this stage of growth? ( i am at 7 weeks )

Thanks yeah they look great! Plenty of buds. The strain is Nirvana Big Bud.

Yes - plants will use more or less of one nute or another at different phases of growth - eventually your nute mix will become imbalanced. Various nutrients are also more or less available to plants at different PH levels. At 7 weeks - typical 8 week strains will use less nutrients. Most feeding schedules taper the feed off at week 7 and then flush for week 8. Having said that, a 14 week sativa will be maxing on nutes at week 7.

I so envy your first picture Stinkbud..

I am using the SB system and have a couple in my cloner and a few in my veg.

My questions are:

1. Is Distilled water the same as RO water? Are they one in the same, or different?

2. With the SB system is there any "pruning" required? I have a few different strains going and well the one has a lot bigger "fan" leaves then the other and is blocking others a little bit. Should I prune? Over all what are the general "rules" for Pruning cannabis?

3. Is 3 weeks in the veg unit REQUIRED? or is this really "per" strain". I have some Goo that is going to just get HUGE in 3 weeks.

THANKS ALL!

Mtn -

RO and distillation are both purification methods that demineralize the water. Distilled water will always have a TDS of 0 ppm. RO will reduce the TDS of the source water by about 90 %, so most tap water starts around 300 ppm, most people who have an RO will get from 10ppm - 60ppm, depending on source water quality. Both will adequately purify the water for DWC but keep two things in mind.

First both methods will lower PH so dont assume its 7.5 cause they will probably be closer to 6 or so.

Second, both distillation and RO remove calcium and magnesium, so you should use a little cal mag with it if your nutes dont have it already. I learned that one the hard way.

Hope this helps!

The most efficient way to produce CO2 is with a natural gas burning CO2 generator (hooked up to the gas from the house). Burning propane is more efficient than running CO2 tanks (and easier to refill). Downside, CO2 generators produce heat along with the CO2. This will increase your cooling requirements. Water cooled CO2 generators are able to run very cool - but they produce warm water that needs to be cooled or replaced. This requires additional equipment and power.

For AC's - if you can afford and have the place to install one - a split unit is best. If money was not object, I would get an AC from one of the following manufacturers:

KwikCool http://www.kwikool.com/

ExcelAir http://www.excelair.ca/stealthseries.html

If you are a regular guy and your room has a window - go to Sears and get a window unit. You can get a 1 ton Kenmore for $300.

lionsroor are portable ac units any good ? my room is a spare bathroom 4.5 feet by 7.5 feet by 7ft. no window 7 dont want to cut a hole in the side of my house

My starting ppm is 678 and my ph is 7.7. What did you end up switching to?

Wow your tap water is worse than mine if your meter is calibrated...

My tap PPM is 550 to start, and thats really hard water. Do yourself a favor get an RO machine. I bought a 6 stage from e Bay for about $100.00. Until it got here, I used distilled bottles from the store for my cloner.

I use the GH liquid PH products.

Hope this helps you.

Since you live in the south do you have central air? You could route it to the grow room to help with keeping the temps down. I have been looking into getting Central Air for my house and I was thinking how to include this into the grow along with taking the heat out of the grow room to heat the house in the winter. Just some thought on how to cut some cost.

It helps a lot.

Now with that said, can you check the pics attached, does that look like calcium dificiency? From this page, http://www.icmag.com/ic/showthread.php?t=11688

I was thinking Boron OR Calcium deficiency. Would everyone agree? Any other suggestions?

I have a few blueberry plants in the same veg unit and they are NOT experiencing this. Only the Afghan Goo is doing this.

History:
I got some massive clones almost plants already from my caregiver. I put them in the SB cloner unit for 2 weeks and they did great (just pH adjusted water ant clonex solution) then I moved to SB dual-aeroponic veg unit a week ago and the goo grew like crazy. ( mixed SB recommended veg nuts in 2/3 of rubbermaid trashcan and then filled lower res with nutes, started out at 800, raised to 900 2 days later and then next day it was at 1050 when I checked it).

This first showed up yesterday morning when I went and checked on them. It has gotten worse since then as it is effecting more fan leaves on those two goo plants.

HELP ANYONE!

PS - The underside photo may appear as though there is something on the underside, there is not, only the top side is effected.
Thanks!

OK, roots question. I have roots in my veg unit that are seeking their way down the drain hole into the res., is this ok? Should I put a screen between the two units in the dual aero unit?

Trim them?

Thoughts?

Just trim them bro... Depends how much longer you plan on vegging them for... But trimming them wont be an issue.

yes i have central ac .and there is a ac vent in the room. my heat problem is from the dehumidifier.i thought the ac vent in the room would be good but when the ac shuts off my air outlet fan is drawing in air from the ac vent and that air is very high rh% . i live in the south and right now rh% out side is 100% . rh in my house now is 48% but my gro room is 68%. need to go turn the dehumidifier on now

this is the toughest part of the year for growing..........
maybe if i had my lights with cool tubes it wouldnt be as big of an issue.....
huge air conditioner and huge dehumidifier

Thanks for those.
Yes, right now, price is a factor. This is why I was wondering about some of those dual hose units I've seen at my hydro store that retail around $5-600. Are any of them decent, if so which brands?

Mtn,

Im no diagnostic expert but it looks similar to the the calcium def I had. I have no idea if the SB nutes have calcium but cal mag isnt too expensive. I use it at half strength (1 tsp/gal) and I dont get those rust spots anymore.

Are the clones rooted already? I dont know much about clones but if you left them without nutes for several weeks after they were rooted, I might guess that may have contributed to the deficiency...

Try the Cal mag and see what happens.

Also, did you say you use use RO or distilled water?

Ladies, Ladies... I've got some good news for you starters. Target has the 18 gal Roughneck in blue for only 6 bucks each, i bought six of em mo' bitches. K, thats it. Happy growing.

Thanks for the advice amigos!

Sure - good portable units work really well... people forget they have to be ducted, exhausted, etc to work effectively. This can sometimes be hard to do - especially to outside - requiring you to cut a hole in the side of the house! Venting your portable out of the bathroom will, at least, require a hole in the door.

Any thoughts on my PPM question - should I be using the CF or EC scale? I have plants in the veg unit for about 5 days and I started noticing patches of bronze/copper coloring on the fan leaves. Would this be from running the wrong PPM number?

Yes sir i would. Ive seen it done many times in basment grows. I would filter still thou. I Could imagine a city worker repairing a pipe near by and opens a manhole only to discover there might be hippies living down there.lol
