Mid Flower Overall Observations
A few thoughts/observations on these plants, the growing styles, training, etc…
-
Pyramid Pots (coco only, ie, Forbidden Runtz setup): Yes, I likely have a very long tap root and lots of feeder roots as was the point of trying this setup. The question is, has it translated into more/improved growth? I’m not so sure. I believe if I grew this exact seed the exact same way in a 10 or even a 7 like normal I’d have a very similar plant. The tap root likely grows the entire grow regardless - all the pyramid pot does is allow it to be straight for a longer distance before curling around at the bottom of the pot. However, the set up does definitely provide more space overall for roots to form in. So I suppose the jury is still out, but I’m not sold on the pyramid pot concept based on just this one plant. Certainly hasn’t made it any worse, just not sure it has made it any better either. That said, after she’s harvested and I peel away the pots, we may get to see a layer/wedding cake shaped mass of roots, which will be pretty cool. That’s when we’ll know how well it worked.
Pyramid Pots with Water Res Underneath (Watermelon WeddingCake set up): This has been highly successful to this point. The plant is gargantuan. Super healthy, super productive. I’ll do this again for sure, with a few changes at least. First, the amount of coco pot up top could be lessened. The magic here appears to be the res - the coco is simply a vehicle to get the roots there. I think a smaller single pot of coco up top and no pot underneath (just all open space in the res) would work better and give more space to the roots. That would also allow water feeding to begin much sooner - she did not get the res filled this time until about the stretch because it took that long for roots to fill the upper pots. I wonder how much bigger this plant would be had she been water feeding through most of veg. I would also do a much better job of sealing the space between the pot and the res lid, as what I have going on is a very rudimentary, rookie job. That part is easy. I might go with the 30 gallon res and just use the one, 8”, holy grail of air stones, which I have already along with the appropriate pump. That would provide a much wider field of bubbles and in theory get even more air to the roots. I don’t see a need for any temperature control for the res, which I mention cuz I’ve seen people using chillers and such. The water temperature in the res has remained pretty constant, and feels cool to the hand - like a cold swimming pool feels. That seems to be working fine. Maintenance of PH and TDS seems pretty easy as well, although I definitely need to learn more about TDS level/feed level based on the plant needs through the various parts of the growth cycle. This time I have gotten away with simply maintaining the res feed level at the level I’d be feeding at were the plant just in coco, so on week 2 of flower the res was filled with week 2 of flower mix (for example). But the increase in growth is undeniable. In coco alone I highly doubt this plant is as big, and the experience of growing the first WWC in straight coco supports this.
@Rexer was right - coco is awesome but can’t match water plant for plant. Or at least it appears so far.
Regular (non XXL) Autoflowers in Coco (White Widow, my first regular auto in coco): I pretty much knew this, but regular autos in coco dust regular autos in soil as well. The WW is huge. Far exceeding my expectations. Also realize where the name White Widow may come from - this plant is shiny, almost silvery/white, from the frost that seems to form on every leaf. I can’t wait to see her in another three or four weeks. I’m also wondering on this plant just how big a pot I can fill with auto roots in coco. I’ve filled everything up to 7s so far no problem. This one is almost filled now in the 7. I mean FILLED. So I wonder if a 10 is worth trying, or if I’d just be wasting coco. Have to try it once in a 10 to see where I can max out roots.
Training: I am totally sold on my “Sombrero Training.” It works very well with enough light. Seems to create a ton of yield and also allows for gigantic colas, which are always fun. I’m finding it works better when topped above the 5th node rather than the 4th. It allows for more flexibility regarding the lower nodes and your lower ring. I don’t think I invented anything here, but it’s a pretty effective style of training and relatively easy to do.
So that’s about it for now. Nothing earth shattering, just some observations to chew on. All of this is liquid - a work in progress, fluid.
Thanks for listening to me babble.
