Hello boys and girls,
The Quest is whole grow efficiency. Now focusing on veg lighting and specifically on how much light per area and what light cycle to use.
I put this under advanced tech section as in FAQ the efficiency was under advanced tech section.
I have looked over couple of sites but I have found fairly little info on how much light to use in veg stage and should the amount used change over the course of veg grow.
While true watts (what is pulled from outlet) are not perfect … it is fairly good and simple. As for area … sq ft … sq m … m2 all good for me. I will try to use sq ft as many users (I guess) are used to imperial system rather than metric.
In rooting phase only very little light … In flowering without co2 35w/sqft a good start point, and after 60w/sqft bit overkill.
While most light setups will work more or less… I do strive to find the sweet spot and rather with less iterations than with more.
Someone pointed out that veg stage is important as plant builds most mass during it.
My guess would be to start iteration with ~ 45w/ sqft. Comments, opinions, recommendations on this?
On light schedule my starting point might be around 8/4/8/4 8on4off. Comments, opinions, recommendations on this? Reason being that the 4h night might be enough for the plant to utilize stored resources (that were build up during the day). Naturally looking to save on energy bill during 8h off.
I have intentionally left out what type of light to use… or what is best… there are many discussions on those already and we have to focus our attention.
Ciao
