Yes I’m running 2 lights 8 plants. I will do more in the future but didn’t want to over complicate it the first time. Also I’m running 220v so it is the cost of running one light.
Surprised no one has pointed this out yet, but your wattage doesn't get cut in half just because you're running 220v, your amps do. 220v just allows you to run more appliances on a circuit, but it does NOT save money.
1200 watts is still 1200 watts whether it's running on 110 or 220.
And just to echo what others have said, definitely shut one of the lights off for a while. Those plants are still rather tiny and aren't anywhere near big enough to take advantage of that much light, so you're just wasting electricity/money. If you have dimmable ballasts, you could even get away with dimming one down to 400 watts and it would still be enough light for those 8 plants. Once things start getting cramped and they're each over a foot tall, then you can think about turning on the other light.
Wish I could get it higher, I keep burning up humidifiers running them 24 hrs a day to keep it at 50
You putting tap water in them? If your water is as hard as mine is, then you'll get scaling in your humidifiers (much like on your faucets in your sinks/showers/etc) and they'll crap out fast. Get yourself a gallon of RO water from a water machine and use only that in your humidifier. $0.25/gallon is very much worth not having to replace a humidifier every month, and if your water is hard like mine is (400ppm plus) then you will be replacing them often. Humidity may not seem like the absolute biggest deal, but it is in fact necessary. Put clean RO water in it from now and, and grab one if you think you'll need a new one.
In another month or so when they start getting bigger, you'll want to take note of the humidity during the first 5 minutes of lights on. This is because when the lights go off, your humidity will rise. During the first 5 minutes of lights on, if your humidity is over 45-50% you'll need to be 110% sure that mold/mildew/etc will absolutely not be an issue for you. If you are not 110% confident in avoiding mold/mildew, you'll need a dehumidifier as well.
As for your setup itself;
i just started my first grow. Was curious on what you veryones opinions are as far as how I can improve or anything I’m doing wrong.
Running 2 600 w lights with a 8 inch exhaust and carbon filter. Temps sit between 75-80 and humidity between 30-50 depending on if I run both humidifiers. Also will be using the roots organic line. Oh at 6.3-6.5 with blue lab. Growing northern lights,master Kush,jack herrer and blue dream. 8 plants total. Plan to do a Scrog.
Looks clean, very clean. Your tent looks quite textbook, everything is properly placed, pH is pretty right on, however as others have pointed out your temps are just a tad too high and humidity needs to be more consistent. Get an air conditioner if you don't already have one, once it starts getting hotter outside I guarantee your temps won't be sitting between 75-80 with just an inline fan once your ambient temps start to rise. 74-77 degrees will be your best bet, you shouldn't be going past 79 degrees without CO2. Better to spend the money on an AC and never use it then to not have it and need it. Don't underestimate how quickly your temps can rise and invest in an air conditioner/cooling if you haven't already. If you live in a state with low enough humidity then you may even be able to get away with an evaporative cooler, will help keep things cool and humid.
However, I'd advise against the Scrog for a couple of reasons and please don't take what I'm saying the wrong way.
Scrog can be an incredible method for increasing yields, but it isn't something I would recommend for someone on their first grow. Scrog will only work when you have an idea of how your plant will grow. Some strains stretch a lot, others don't stretch at all. Some strains you'll need 4 plants to fill a 4x4 Scrog, some sativa dom hybrids can fill a 4x4 Scrog with a single plant, and some indica strains might require 9 plants to fill the same 4x4 Scrog.
The main issue that comes to my mind with you doing a Scrog doesn't even have much to do with the fact that this is your first time growing in general, but you have 4 strains and no experience growing any of them. The biggest hurdle with going Scrog or even SOG is knowing 100% about the strain you are using. You could have years of growing experience, but running a new strain in a Scrog won't always give you optimum results. My current grow could be a good example here, I'm running Mendo Purps, Jack the Ripper, and AK Skunk now. The Mendo is vegging like mad and the only one that isn't single cola dominant, so I put 3 of them underneath my screen and let my single cola dominant strains (JTR and AK) grow like normal in a vertical set up. I'm using two different growing methods (Scrog and Vert growing) because different strains require different methods for growing.
You say you're growing Northern Lights, Master Kush, Jack Herer, and Blue Dream. With Scrog, you typically want one strain per screen because you're going for uniform growth. An indica dom strain like Master Kush and Northern Lights are not going to grow uniformly with Blue Dream.
Jack Herer is tricky, because in my experience it has a handful of phenotypes. It will either grow similar to your Northern Lights strain or it will grow like Haze.
If you're dead set on using the Scrog method, I recommend you start taking notes on the way each of your strains are growing. By then you will have a better idea of how they grow and if they'll do well underneath a screen. I'm assuming you went with 2 clones of each strain yes? If I was growing in your set up, I would likely put the Master Kush, Jack Herer, and Northern Lights underneath one of those 600 watt lights in 3g pots. Those 3 strains are going to have more indica like growth (I know Jack is a sativa hybrid, but in my experience it takes after Northern Lights quite a bit in terms of how it grows) so they won't grow and stretch very much. All 6 of those clones in 3g pots would be perfect under a 600w light.
Blue Dream on the other hand? With enough time those 2 Blue Dream clones are capable of filling those screens all by themselves, there's a reason commercial growers love Blue Dream so much, you can't fuck it up and it just doesn't stop growing. Those 2 BD clones are going to stretch, and hard. They will out grow everything in veg and will stretch WAY more than the other 3 strains you've got going. Those 2 BD clones could fill a 4x4 screen by themselves effortlessly. If it were me in your shoes, I'd be aiming to have the 2 BD clones underneath a Scrog and just leave the other 6 under the other light with no screen.
I'm not trying to be a dick or discouraging by any means, just realistic. A good Scrog grow requires you know everything about the strain(s) you are growing, as well as the ability to foresee how things will grow, where the branches should be tucked, how to trim and maintain both your canopy and the underside of the canopy, and of course you'll need to be experienced with topping and training.
I recommend doing the Blue Dream in the Scrog and that's it as Blue Dream will do all the work for you. The other strains should be grown normally. Don't go too gung-ho and use this grow as a means to practice and gain experience. After your first grow is done, reflect on it and figure out what went wrong, what went right, and what you could do to improve on things.
The absolute biggest mistake anyone starting out indoor growing can make is spending too much money without yielding good enough returns. Again, not trying to be a dick, just wanting to save you from some of the stupid mistakes I made myself. Looks like you spent a decent chunk of change on all of that equipment and the nutrient line up, I'd guess you've already spent close to if not over $1000? That doesn't even include your electric bills either, you're looking at around $100/mo (depending on your charge per kW) a month and that's just for your lights. Growing can be incredibly fun and rewarding, but if you go too balls deep without knowing what you're doing then you'll end up wasting a lot of money. I've made this mistake before, wasted plenty of money on my first grow and ended up with weed so bad you couldn't even call it scwag. Not only was I out $400-500 for the shit grow, but I ended up spending money on weed anyway. Gain some experience and knowledge before going too crazy my man. You wouldn't spend $1000+ on cooking equipment when you still don't know how to make an omelet right?
Just trying to be helpful and hope you don't think I came across as an ass. I'm just someone who's made plenty of mistakes in my time, and in fact still do so. You're on the right track. Get yourself a grow journal going and don't be afraid to ask questions. And just remember, at the end of the day it's just a weed. Don't baby them too much, don't overwater/over-fertilize, be patient, and ask questions. I'd also recommend that you post pictures/get advice before you flip your lights to 12/12. In veg, you can recover from literally every kind of problem unless the plant is just totally dead. In flower, you're SOL.
Hope this helped.
