What did you end up going with the 1" or the 3" did you have any luck finding the parts
Click to expand...
I did...finally found the feet for the 1" spacers and they arrived today. So the plan is to use these PVC spacers and place my tubes in alternating rows. My row spacing is going to end up being approximately 11 1/2 inches and my plant spacing on the tubes is going to be 5 1/2" on center. So still pretty tight but a lot more room than what I have been doing. And really, the big difference here is going to be 11 1/2" vertical spacing.

No, not really. A few gnats towards the end but that was about it. Yeah, the buds are pretty disappointing. They definitely smell good and are sticky but they are really loose and leafy. Almost embarrassing. Oh well, I guess those are the breaks sometimes. Just gotta keep trying different things.

hahaha youve got nothing to be embarrassed about bro this was a fantastic log and I learned a lot! thanks again for seeing this run through to the end. :D

QUOTE="Sativied, post: 11640183, member: 539919"]Just thinking out loud, but if the perlite is dry and the coco wet the roots would grow towards the wetter side. It's something I need to keep in mind with small plants in large soil pots too, in that case watering from the bottom (letting the medium suck it up) or at least soaking it thoroughly every watering encourages it to use the entire pot. Water moderately from the top has the opposite effect and tend to turn the top layer in a root mass. From what I read you water plenty with run off, but is that drain at the bottom or on the side like a hempy bottle? Perhaps the coco+roots suck the perlite dry before the coco dries out? Based on the size of the plants and the amount of them I did expect more roots. Just shows again what a great job you did though, keeping them healthy with less roots is even harder.[/QUOTE]
I think Sativied is right with this. If you grow in airpots the root ball is thick but they stop/die off where they leave the media. Its called air pruning and makes the root ball fill in more than trying to grow long and binding up at the edge of the pot.

Those pictures are using the 3 inch spacers which makes the row spacing over 15 inches which is just too much. Going to be 4 rows total.

Looks like a good design. I think the vertical grow will get you closer to your goals than the flat SOG. If you end up with more total height for the four rows than you want, you could set your bulb up with a light mover.

Chapter 3 Update
Day 0 - Official start tonight or tomorrow

Here is the setup:
20150603_103418.jpg

5 sides of an octagon. 4 Rows.
Each side has 5 plant sites spaced 5.5" on center.Row spacing from plant to plant is 11.5"
Total capacity of 100 plants.

This is a recirculating design where water will flow into the top tube on the left and then exit the lower left tube back into the reservoir.

Diameter of this, measured from the center of plant sites, is 75 inches. I've built a full octagon that was 90 inches and one that was 60. 90 was too big...60 was too small. Hoping this will be just about right. There are a lot of variables at play such as:
  • How much will the plants lean towards the light which is hung vertically in the middle.
  • Will the tubing that returns water to the reservoir become obstructed by roots?
  • What impact, if any, will the roots have on the overall water level in the tubes?
There are many more data points I intend to collect but these are the main reasons I opted against building a full 8 sided octagon. As you can imagine, a full octagon poses many access challenges and I did not want to have to add those challenges for this experiment.

Tonight or tomorrow morning, I will be germinating the following in 1.5" rockwool cubes in 2" net pots:

  • (40) Humboldt Seed Organization Blue Dream
  • (20) Humboldt Seed Organization Blueberry Headband
  • (20) Humboldt Seed Organization Sour Blueberry
  • (20) Female Seeds C99
All of the seeds are feminized.
It is important that the seedlings have a tap root extending no less than 2 1/2" from the bottom of the net pot. Because of this, the net pots will be semi-buried in perlite. I'm hopeful they will able to be transferred into the octagon within 14 days.

Another update will come once the seeds have germinated, the water intake and return are completed and all of the other misc parts are up and running.

Looking real good. I put my 20 hso blue dreams in a cup of water last Sunday for 24 hours. After that I use the paper towel method Monday night. I checked them this morning and 19/20 all rooted nicely. I'm sure you should have no problem with the blue dreams. Plus I think I bought them last year too.

Chapter 3 Update

I'm a little late getting started but the seeds went into rockwool on Thursday. Everything is tested and water tight. I've got the seeds sitting in perlite because I need them to grow their taproot out of the net pot by about 2 inches before I can transfer them. Hopefully it works.

The only other thing worth mentioning is a minor line-up change.

  • (20) Humboldt Seed Organization Blue Dream
  • (20) Humboldt Seed Organization Blueberry Headband
  • (20) Humboldt Seed Organization Sour Blueberry
  • (20) Female Seeds C99
  • (20) Barneys Farm Chronic Thunder

Love the lineup - that should be a lot of amazing smells in one place!

I hope so. I swapped out the extra 20 Blue Dream for the Chronic Thunder for a couple of reasons. Since I've grown the CT twice now I can use it as a control plus it's somewhat unlikely that I'll grow it again so use up the seeds. This will leave me with 20 seeds of each of the other 4 strains.
