Just a point on mars hydro recommended fan Size or any other for that matter.
There's no one size fits all. It's based on temp coming in.
I wouldn't worry about the 2x2 if the temps and rh are good
Exactly..
We need more tests with more cultivars.
It's all well and good witnessing how they respond in veg, but how does that translate to flower and the end result.
They also do a lot of growing in the dark.
It doesn't have to be 18/6 or 24/0
You can have anywhere in between.
I subscribe to a dark period, so if its winter 20/4
In summer 18/6
See that's the problem.
Lot of light and not enough heat.
Though I typically veg with MH, I've found with LED it's best to hit them with 25%, then 50% as they get used to it at 18/6. Then 100% on flip to 12/12
You would actually get better growth at lower intensity because your not trying to...
Crazy isn't it.
Think they were advertised as fd6500 @ £309 but go down in price the more you get and are actually fd6000s, same as my other one.
The add is very confusing though.
I had to message them to get confirmation on exact size and wattage just to be sure.
2 of em are for another mate.
From what I understand the omega is a few points lower umol per joule than my omega 3.0 but your getting more total light output out of that on full whack cuz it's 720w.
The other will be much the same.
I got a mate of mine on a couple of em , bit cheaper than those but can't find them...
I'm sure we've probably discussed before but..
Bump your temps up more, 82f minimum
How many hours of light and what wattage per How many feet of floor space?
I've ran a few set ups in the past using one fan with two tents.
For it to work everything has to be fairly equal.
Length of ducts, thus resistance, and tent sizes.
The issue you've got is the 3 tents are different sizes , the extraction will be divided equally between the 3 but that means...
