Here is the update. These sprouted from seed four weeks ago today.
A quick recap for those just joining: 4 plants in a 3x3, sprouted under CFL, put under 600 watt metal halide for veg, and will go under 600 high pressure sodium for flower. Have a 400 CFM fan pulling air through the hood and out the tent.
The first two are an overview of the four.
Here are some height and width shots. The height pic is of on my tallest, #4.
#4 has always had a bit of a differen look to her. Always just a tad taller, and that height is starting to show more and more. She is a solid 1" taller than the others, perhaps up to 2".
This next shot is of #3. She is the widest, bushiest, and in my opinion, the best developed of the three. I think this is because I did a better job unbundling the rootball at transplant. Or maybe she's just a strong one. Either way, she is beasting right now. The stalk picture is also of #3. You can see how well close those first few nodes are before they start seperating out. Also, you can see a growth shoot starting out from where the cotyledon was. Weird...never seen that, but my first grow.
An interesting note on #3 is that when I initially put into the Fox Farm Ocean Forest to sprout, it had the worst nute burn of the four. It has since developed into my best plant. The absolute lowest, first shoots that grow out have almost caught up to the top, and the stalks are thick and strong. I have little doubt this will be the best yielder of the 4, when I thought it was the weakest.
The final picture is the temperature and humidity as I opened the tent today. This device sits on top of the soil, so it's a good guide of what the plants are feeling. Humidity is up a few points from normal, due to watering yesterday, I think. It's usually in the mid to upper 40s.
Anyone with any ideas on how much longer to veg? I'm thinking no longer than two weeks. But maybe I should sooner. Any input appreciated.
