Help me understand correlation between soil amount and plant yield.

[Guest]

Just to chime in... I clone using rapid rooters, rockwool, ez-cloner, or peat pellets. Plant the rooted clone in 32oz clear potato salad container. Veg under flouros until about 1ft tall; Approx 4 weeks. Uppot to one gallon pot for one week under 800w dual spectrum HID's. Move the one gallon container into flowering under 1kw HPS. I use a flood style table, bottom feeding. When dialed in I have yielded as much as 38 grams off of one LifeSaver. Usually pull down 25 plants averaging about 22 ounces from each table. So it is safe to say that one ounce per gallon is about right. I started in 5 gallon grow bags but noticed that they never used all the dirt, so I kept bumping down the amount of dirt until they were rootbound at the end of flowering. Ended up at about a gallon, so I switched to gallon pots.

Pics in my gallery of the pots.

That is definately an interesting approach on your grow method. Seems like quite an effort with the dual spectrums, 1k light, and the flow table to pull slightly less than an oz per plant, but I consider anything over a pound per 1k light a successful grow.
I love those potato salad pots you are using.

I am usually shooting for 9-12 plants at 3 or more oz's per plant, in just regular old nursury pots, and hand feeding. I have not been able to get over 3 oz's per plant on the Sour Bubble consistantly, but I only veg them 6 weeks so I can get more grows in. Most other strains I grow I can clear 3 oz's per with minimal effort including Lifesaver which is one of my favorites.

Growdocs a bad example,hes using beds and unrooted clones(which would be more compact if he was using wee pots,tho that would be extra work for the guy,so who can blame him,with them numbers)and seed.

I used grow doc because he used beds rather than pots. How much more room can you give roots than that. And his buds dont seem too airy.

Strainwhore do you have a sun systems 800W combo,or the growzilla?I have the sun systems,I believe its much better than growzilla.Growzilla buts their lamps side by side which is not good IMO wheras sun system has them end to end like it should be.Its a great vegging fixture for sure,I use it before going to my 1K MH for veg

Dude "unrooted clones"

 

[Guest]

Tell you what GMT,i would like to see 1week rooted clones in the same bed,and seeing as a dont have a galley myself mate,i cant be negative about anyones plants

Good stuff here everyone. I think its important for soil growers (especially relatively inexperienced growers like myself) to have a grip on the mechanics of root growth and transplanting beyond tossing another bag of soil into an oversized container. Rules of thumb like a zip per gallon and successive potting up are good to know, but its seems to me that understanding the timing of these steps and being able to read where your plants are at can really lead to improved yeilds.

Here's a question. Would an extra week of veg between the final transplant and flipping to 12/12 add to a plants root mass? In theory you would get whatever roots the plant could add in that week plus the roots the plant would kick out during the stretch. Or on the other hand, would the plant just spend that extra week recovering from the transplant stress?

Great question.

One thing I have to do is draw the line on veg time. When you grow with 1k systems, it is very expensive to run those lights and you cant always wait for the plants to show sex before flipping 12/12.
From seed you have to expect 50/50 M/F and to up-pot all the plants prior to determining sex is a big waste of money, time, and effort. I only use 1-2 good looking males for breeding, so to up-pot all of them before 12/12 isnt worth it.
Now for clones I definately up-pot a good week before 12/12, for the rare occurance of transplant shock, and I know all will be females so it is worth the effort and I do get great results.

I have been up potting after flipping 12/12 and sexing for seed grows for as long as I can remember and really havnt noticed any negative results. I have pulled over 5 oz's occasionally from 4 gal pots using this method.

Clones only for me prior to 12/12.

Thanks! I save every one I can get my hands on... There really isnt that much effort. I've got it down to an assembly line basically. I reuse my bloom soil as veg dirt. I dont ph the water or feed them anything while they veg. They spend all but one week of their veg time on my shelf system. I bottom feed the trays. Pics in my gallery.

I notice the huge boost they get when you turn them over to flower; but I also noticed that if I uppot them the same day I turn them over, they are shocked for about a week, so they really only got 7 weeks full flowering.

SOOOO since I had a Northern Lights Company dual 400 laying around (to answer Skeletors question - shitty hood, just bought a growzilla) I decided to pot them in their final pot a week before I turn them over. I give them a nice shot of transplant solution at uppot and after they go into bloom. Full Earth Juice line plus Fossil Fuel (humics), fungi, bacteria, molasses. I have noticed a substantial increase in yield. 3-4 ounces a crop increase. Once they are settled in the bloom room, I simply dump 10 gallons of fertigation water in the flood table to feed them when they need it. NOT a full hydro flood table set up, just a wooden box lined with pond liner. Saw it done in High Times with the most amazing Citral growing in it. Have been trying to duplicate that guys grow ever since.

My new bloom soil mix is a modified Moonshine Man Mix / Coco Fiber / Perlite - a 1/3 each.

I am thinking about changing the way I veg. Seeing Chemdogs grow in the High Times Master Grow Guide - I want to start vegging them for only one week in 1 gallon under HID, then uppot them to at least 3 gallon to see if I get more out of the same space. I can get 3 gallon pots that are almost the same size as my gallon pots. I will post the results.

On a side note - If anyone has ever heard of Dr Greenthumb, he used to have forums on his site and he stated that he blooms out all of his plants in 5x5x5 Kord pots...it was discussed on OG once. 5x5x5 - thats only a half gallon of soil, but the results were fucking amazing! I am sure he had his work completely dialed in and fertigated with every watering, but I thought I would share.
