A Question About Light
@StoneOtter Earlier we talked about the
@ViparSpectra XS1500 Pros a bit in the swick thread. I want to follow up on that please.
I started my seedlings at 25 %, then moved them up to 50 %. They are vegging now and two days ago as you know, I raised them to 75 % but have subsequently reduced them to 50 % and to recover from what could have been too sudden a boost of extra light. Maybe the lights were too intense and too close all at once because overnight, the Parmesan showed the calcium deficiency and the Gelato showed some yellow flecks on the upper leaves.
However, another thing to consider is that they are doing a pre-flower stretch and maybe what they needed was a boost of microbial activity. I gave them microbes and microbe food with their calmag and all looks well several hours later.
I am going to raise the plants back onto their swicks when I feel they have reverse wicked sufficient moisture into the towels. That'll raise them back to where they were before I increased the light intensity two days ago. What I want to know from you, is how and when to increase the intensity back to 75 % and how to establish the optimal distance from the plants at 75 % please. Still no pistils yet.
Anybody else who has used the XS1500 Pro lights please feel free to contribute with your ideas and experience.
top notch work my friend
I can't wait to see how they bud up!
I am happy about the plants today but annoyed a bit because my fan died. Fortunately it's cool weather but I'll have to get a replacement tomorrow.
Far more important than maths and science!
