40+ lbs with 12 Plants in 2 Rooms on a Flip

[CloudHidden]

Sometimes you just get geographicaly lucky. Today I went to a really cool place just 30 minutes away in Florence, CO. Persolite Products Inc. They sell perlite CHEAP! $7.50 for a 4 cuft bag.

Really cool people too. I enjoy doing business with places like this.

That's crazy! I'm only a little further (40 mins) away. Had no idea about them. Thanks for sharing.

Bro, drop me a PM sometime, we should hookup for a sesh someday.

So I made 3 different mixes to test this run using the DNA Mills Coco / Cork.

I will use this mix on one row and on the odd ball plants.

3 Parts coco/cork
2 parts coarse perlite
1 part coarse vermiculite

One row will get this mix:

3 Parts coco/cork
3 parts coarse perlite
1 part coarse vermiculite

The center row will get this mix:

3 Parts coco/cork
2 parts coarse perlite
2 part coarse vermiculite

The center row is where they drink the fastest, maybe that extra vermiculite will help. I expect that center row to be pretty thirsty since it will have the 1500's on light rails moving down both sides. I really have no clue what the watering frequency will end up like on these mixes but I am fixin' to find out lol. Might end up wishing I had added more vermiculite to all of them.

Since I have the hookup on the Perlite I may try some straight perlite with some vermiculite perhaps. Maybe test straight perlite against perlite with some vermiculite? I might play with that some in veg first.

I have installed the light rails and 1500's in room B, changed out 5 of the six 400 watt HPS row end lights for 240 watt 6 cob setups that will give better coverage with less watts and less heat, allowing me to run the 1500's. I am considering moving the carbon filter thats in the corner so I can swap that 400 for a LED as I have three more of those fixtures built.

I have a few more fans on order as I am changing things up in there to facilitate even better air movement.

All in all this run will be a real experiment, always learning and trying new things keeps me from getting bored and frankly I am tired of fighting the pH on the different peat based mixes that are available and that is a variable even with the same product and different batches. I will be running the divine gelato 3 in the rows and probably mimosa for the 2 odd balls. Also considering giving the chem gro 4-20-39 stuff a try. See if they like that, but first I think I will stick with the GH just to figure out the new medium mix and then try the chem gro on a row to see how it compares.

Got some new cuts from my homey, one is the Pancakes. Probably be giving these a try in room A, I will be staggering these again.

Happy growing folks!

I suggest looking into adding some biochar to your soil mix. It works wonders for buffering nutrients and pH.

Room B modification completed. 1500's on light rails, LED fixtures on row ends. Some new fans in the mix (ceiling).

Looks good!

Are those Timber LEDs?

So one initial observation on the chem-gro 4-20-39 after just mixing it up once.

You can't make any sort of mix thats rich enough to be considered a concentrate. You get this stuff wet it needs to be in a large volume of water thats being mixed as it's added. Failure to do this will cause some of the compounds in the bag to react and precipitate out. So this eliminates any possibility of using my magnetic stirring plate for this one. Instead I just used a 10 gallon bucket and put about 5 gallons in with 60 grams of the 4-20-39 that I added while I was running a paint mixer on a 1/2" drill lol. Get it to about half speed and it's really churning but staying in the bucket, more and well, probably need a bigger bucket lol. I didn't see any precip after mixing. I tested about 30 grams in a liter of water on the stirring plate and you get a ton of precip. I don't know where the line is but my gut says don't try to get any richer than the 60 grams in 5 gallons.

I mixed the calcium nitrate and magnesium sulfate on the stirring plate in about a liter of water and then added them the 30 gallon drum after the 4-20-39 is mixed in. I didn't see any issues with precip. So we will go from here and see if the plants get pissed or not I guess.

Trying to figure out what pH level they wanna be at, so far I have been going with 6.2 but if I see any mag def I will try raising the pH before just adding more magnesium, they are getting 2 grams per gallon of mag sulfate so there is no way I am not providing enough magnesium, if anything it's too much but I figured with the coco the extra 2/3 gram per gal over manufacturer mix instructions (1.33) should get me anywhere I need to be. lol

These are the manufacture baseline recommendations:

-20-39 Recipe – For a great baseline would be 2 grams per gallon of 4-20-39, 2 grams per gallon of CaNO3 and 2/3 that amount of MgSO4 (1 1/3 gram per gallon). We suggest you try to keep your pH right around 6.2 for the duration but some fluctuations are not uncommon. During middle weeks of flower, you can add 1/3 the amount of MKP for extra K (potassium). Certain strains can tolerate a higher EC than others and you are welcome to push those strains if you like but we feel the base mixture will do a great job,

So my 30 gallons got 60 grams of 4-20-39, 60 grams of mag sulfate and 60 grams of cal nitrate.

I can see myself being very likely to increase the 4-20-39 a little and maybe backing off the epsom a tad. Right now as mixed it's only around 875 PPM with tap h2o so there is definitely room but lets see what they think.

Anyways, enough of my random babble. Happy growing to all you good ppl! Stay safe from the 'VID

I used their 5-11-26 mix and I did have some stuff settle. It didn't matter if I mixed it back into solution or not and the plants were happy either way.

 

[Renfro]

I used their 5-11-26 mix and I did have some stuff settle.

I ended up with a lot of precip. I let it settle in a 1 liter flask and it was about 1/2 inch deep on the bottom. Mixing it in the larger volume of water eliminated that issue so I should be good to go.

 

[Renfro]

So far I am noticing that the vermiculite I added to the new mix has really helped the coco sustain longer watering intervals. Of course the real test will come in mid flower when the straight coco was needing water every 4 - 6 hours.

On a side note, my homey threw me some Animal Mints cuts to play with. He had given me an Animal Face cut that he gave me a few more of those as well. It's good to have buddies with the connections for breeder cuts, thats pretty much all he gets. Pancakes, Space Runtz and one called "Fire" lol. I guess room A is going to be a genetics test run, the Animal Face is supposed to be much like the Glue so I am stoked about that one, just got the cuts late so I won't have a row of it but maybe an odd ball plant or two? We will see, tough choices.

My back is killing me, gonna take a few dabs and veg out in front of a movie.

 

[mistergrafik]

Animal Face .. I lost my only cuts during a move. Man I wish I still had her. Didn't have any of the colors I wanted on the pheno I got but nonetheless - Was able to flower one & it was heavy. Threw a few bananas late flower; there was a power outage that I blame for it but as always keep an eye amigo!

jumped to the future and subb'd to ur next grow fro. You should do something to achieve a full row of the face if not a room full

 

[Renfro]

Thats what my buddy says, maybe I should take cuts of her for the next room B run? That would be next year but, if I go for a row of her now it would delay the start of room A by a few weeks and the plants I already potted would have age on them... I dunno, sometimes the logistics work themselves out in veg lol. Too many choices. I could also consider a tent run using the LED, maybe use the ebb and grow controller and setup one plant in there in a 10 gallon perlite bucket. lol

 

[mistergrafik]

Could be worth a mother to full room! Next year isn't far away - and no delay on your room A ..

Or you could just blast one mega dank plant through to flower in the LED EBB & RENFLOW tent.

Either way I'm subb'd. Me & my cat

Just a thought, but have you tried covering your grow containers? I run sub-irrigated planters boxes and cover them. Soil evaporation starts at the soil surface and works downwards. A plastic cover over the top helps to create a rainforest effect trapping moisture evaporation and conserving water at the same time giving your dehumidifier a bit of a break. Feel free to ignore me. Your killing it!

I did try that with a few grows, (the last couple), and I didn't notice much difference in humidity or watering frequency.

Wow that's a lot! I made a stock solution of 200g/gallon of the mix, using at least 8 gallons at a time. I used 5 gallon buckets and boxed them painter style to be sure everything was well mixed. I ended up with a thin layer of precipitate but nothing like that! I also started with hot water as that helps things dissolve more easily.

Double check the mfr's instructions; I originally ignored the step of making a stock solution and it was not a good move.

whats up bud, hope all is well.

same shit, different day. you know the drill! lol How are you buddy?

 

[Jenko]

What did you get in weight of the first grow??

 

[RegularRhino]

I just finished reading all 92 pages of this thread... wow and thank you Renfro! I am so glad that some states are starting to allow cultivation outherwise so much of this accumulated knowledge would not be reaching as many people. I am also glad to see that you got you plant count increased a while back, that much talent needs to be fully utilized. Thanks again for taking the time to share here, I am subbed for sure!
