when i first started growing, 4" fans (and hoods etc.) were common. i didn't think they made them anymore, lol...
Any Experienced hydro growers? Need tips on growing hydro.

SQFT is assuming 8 FT ceilings.
4" 200 CFM = 50 SQFT
6" 530 CFM = 130 SQFT
8" 670 CFM = 170 SQFT
10" 810 CFM = 200 SQFT
12" 1140 CFM = 285 SQFT
Those are running at 100% exchange every 2 minutes, that is the fastest you should ever need to run exhaust, absolute worst case scenario, add a speed controller and drop to half these speeds and you should be able to keep temp/RH without the hurricane and wastefulness.
A 12" fan can empty my entire home of it's air in about 20 minutes (over 3000 sqft, aka 25,000 cubic feet.) If you exhaust outdoors overkill is a huge expense, you have to heat or cool way more air...
I run a 4" 190 CFM fan at 50% in a 4x7 with over 2100w.

My point is that a 12" fan is cheaper than buying 2-6" fans.... as is a 1000w setup compared to 2-600w setups. Obviously you missed that.
And hes growing 3 plants this time.... what about next time?
What about in a year?
Having one large fan is the way to go. Run splits and controllers but it is most cost effecient in the long run if you have any plans of expansion

Your not running vented hoods?
You can use a little more air flow with 2100 watts to keep them a few degrees cooler. You dont Ned to set things up so all your air is being replaced... I never even brought it up.
Run outside air through your hoods then back outside. Run a split for a carbon filter.
120cfm for 1-1000w hood will keep it cool. Anything less than 75 and your getting some good radiant heat in your room.
Also.... I grow in a shop with a lot more sq ft. I experienced having underpowered equipment first hand... it sucks

i like to dry 45-50% rH round 60*F for 6 or so days.

A 1000w light with 6" fan in a 5x5 space with 6 plants is perfect imo. I'd do 6 plants and run ebb n grow buckets. It's pretty much idiot proof and with only one res for all the plants, it's easier to maintain, easier to control water temps (look out in Dwc, you'll get root rot if your not careful and it can be the biggest headache, especially for a noob) If temps get too high. Yeah, the ebb bucket systems are kind of pricey but you can upgrade the system to run 48 plants. So in the long run its cheaper than most set ups.

Right on man, I saw those online somewhere, I want one too, it looks so beasty with the tubing they use lol. I'd rock that thing out no doubt, maybe some day. What's the price tag on one of those?

Hydro is way easier than soil. If u mess up all u have to do is dilute ur res. Way easier than soil imop

really? things happen fast in hydro, you need to be able to respond quickly. i guess some could, and some couldn't.

The key to great taste and smell is 50% genetics and 50% conditions. If you keep a plant in optimal conditions it will produce a better terpen profile which gives you more taste amd smell.
When curing, hang the whole plant afyer cutting fan leaves off. Leave tue sweet leaf until the stems crack when you bend. Throw them in jars and open the jar twice a dday for one week, Rollin the jar to create new surface air on your buds. This is called decarbing and will purge the chlorophyll from the plant matter. Once youve hit the 7 day mark, ooen the jars once every other day for another week.
If the buds start feeling soft and spongy, let them sit out in the open for a couple hours.
After the cure the smell will come back.
I get better smell leaving sweet leaf on, and it protects the trichomes on the bud so they always look fresh

If you have a good ph meter and ec truncheon then hydro takes allthe guesswork out for beginners, it does however require conditions to stay dialed in. The extra work was worth having no second guess stress for me

Good info on the drying and curing MD
