There are 2 ways to go about it...sterile or beneficial bacteria. The above mentioned thread has excellent advice on sterile. I run Hydroguard but I have an aquarium chiller on my rez and keep temps 65 to 69f.
If you have bad smells you have a bad bacterial infection and choices are to clean and...
I run a 50/50 mix of OF and HF with 30% perlite added. Like others have said the first 3 to 4 weeks will need nothing except maybe calmag depending on your water source.
I'm assuming your a new grower so I would suggest if after the 4 weeks you feel the need to add nutes(depending on your light...
I'm a big fan of ir and uva..I added it around a year ago to one tent....now all 3 have it. I'm convinced it adds flavor and potency along with better yield.
I'm anxiously waiting to hear reports on how the "mint" white diodes perform. Let us know!
My vote goes to grow it out.
Looks pretty good....dark green in the bud and looks happy.
There are a lot of lessons to be learned yet...no need to toss the opportunity to do so.
You are getting really close to a harvest window but it takes a look at the whole plant to tell how close...I personally lower my nutes but continue until harvest. That decision is up to you.
When checking trichs make sure your looking at the calyx and not the sugar leaves and consider the...
Yes I have 2 Mars fc8000's with uv/ir add on bars in 4x4's and a Spider farmer se5000 with uv/ir in a 3x3 but I never run any of them past 75% which will extend their life....hopefully
Odds are you'll never need all 1000w but it's coverage will be much more even and complete than what you have...
You could definitely get more out of your 5x5 with a stronger light. 450w for a 5x5 is on the low end....30 to 40w/sq ft is the general rule of thumb. So up to 1000w on the high end without co2.
If your going to make the plunge look into adding uva and ir too :eyesmoke:
Your sacrificing a bunch of head room with that tent...like Bullmark said I'd grow in there without it.
Cut a hole in attic board to vent through if it's a vented attic.
