I am actually going to replace the inner lenses with the 50's. Either the inner 4 or 8, I'm not sure yet. I'm getting 1000µmols form 39" with only about a 12 more inches to raise my light, and the plants are creeping up on 18". So if they double after stretch, it will be around 1500+µmols. I'm shooting for 1200µmols. The outer edges are great though. There is a big differce between literally the edges of the 4x4(300µmols), and 3.5x.3.5(600µmols)...some of the plants in the 3.5x3.5 zone even have some branches getting 700+µmols. Now that I am not just focused on the testing chart dots, the coverage is better in practice. Doing a little lens work will should keep it at closer to 1200 at 24" and still keep a good strong curtain of light on the out edges.
For comparison here is 2 days ago,
Now Today...
39"
You can see it looks like mag or N starting...that's the broad ties effect on the plants health. They seem to have liked the treatment and are a shade darker today. So time will help push through.
Branching and main shoots are doing great
Here is my little DWC project I transplanted form the 3gal soil
Was aclone, but it was mainlined to 4, then they went to 12(3each) and is super bonsai'ed out.
I hade to totally cut a hole in the bottom of the net pot to pull the roots through.
Some early results with the ESC already. For next 3 pics...
Left is control and
right is ECS treated at transplant 28 days ago.
More roots=more fruits. There is roots coming out on all, but the ESC tend to have more, brighter, whiter, and bigger ones showing.
