Before I drop an update so we can all
‘ooohh’ and
‘aaahh’ over newborns, here’s something of interest.
Some of you will be aware that this phenomenon of super tight node-spacing has happened before with this light of mine (and me wielding it!).
I wondered a lot while growing the Blue Dream last year whether the light was not quite right and that’s what caused it. Maybe it contributed, I don’t know. But the way it’s happened again with these new ones looked so similar to the BD it set me wondering again about the combination between intensity of and distance from light, and whether I wasn’t getting this quite right. I’ve been using the lux meter this time to set things and I hope this will help.
So recently
@Heavenly Hybrid pointed me towards an instagram post by Nebula Haze which is relevant to this. Nebula started some seeds under a QB for the first time (4000k HLG 65) and they actually sprouted multiple nodes without even breaking out of the soil. And the nodes were pretty much on top of each other. Like, in an
impractical way lol! They have no stems!
Here’s a screenshot...
Now, it was identified out that NebulaHaze had her QB’s waaaaaay too close at only 1.5’ so this is an extreme example. But many responders to the insta thread agreed that QBs too close will do this.
When I grew the Blue Dream I didn’t have any measuring device so for this run I got the LX light meter that measures lux and looked at the RQS guide for using lux to set these style of lights. I also read around this site and elsewhere that, while RQS suggest 5000lux for seedling, that up to 20,000lux was ok. SO I had these ones, the Candida and Bubba at about 15,000lux at 3’ away I think and I think that was too much.
I think I might build a germination station sometime down the track. I was thinking about it for this one but time ran out.
At this point with my new seedlings 4’ from the light they’re coping about 11,000lux and maybe that’s too much still, but if I drop the intensity, or raise the light any more I can’t get the light I need to the older plants. So, either a germination station, or construct some screen covers for use in the tent to reduce the intensity for babies (and clones!).
@InTheShed has successfully used fly screen to do this so I’m thinking about something like that, or the light diffusing plastic I used outside.
Anyway, I just thought this very interesting, so thanks HH for bringing it to my attention.
It doesn’t explain why that Blue Dream
continued to stay flat and not really stretch in flower. But I’ve learned some things recently that tell me those aspects probably had more to do with my pruning and topping practices (and not getting it quite right).
Updates dropping soon
