Questions about my setup. (My first Dwc grow)

[Toker1]

I run two 300w Mars hydros in a similar space. I keep 4 bonsai mother plants that can push out approx.150 clones per month.
The major issue I see with flowing with those is the 3w chips do not penetrate far down. You really need the 5w chips for flowering to yeild decent. HID lights will yeild higher than the two 300w MH.
I would only expect a few ozs yeild.
The humidity is a bit low, unless you are at the end of flower. Also the light up 30” is way to high for veg. I think mine are like 5-6” away from the canopy. You should lower it incrementally one day at a time and see how they react. A PH of 6.7 is getting up there. Try PH down to 5.5 then let it swing up to 6.5 before you drop it back down to 5.5 again.
Feel free to ask about DWC here. Been doing it for years. Good luck on your current grow!!

Welcome, young Jedi...

Looks like you have it on point. DWC isn't difficult, try and get into a routine of checking pH of the bucket daily. That's one of the best indicators of troubles brewing. My nutes will buffer down to 5.5 when they are mixed and I will slowly raise the pH over the course of 7-10 days between rez changes. This allows the plant access to micronutrients locked at either end of that pH range(5.5-6.5). I started with a pair of the oriiginal Mars 300's. Mine pull about 125W each. Older, less efficient diodes like those used in these fixtures need roughly 50W/ sq ft of consumed energy to give you adequate light levels. If you can manage the heat load, I would use both during flower to get a better result.

If your lights are the old model Mars300, those are nice lights,
Don't know nothin about DWC though.
Several folks use those old model Mars300, maybe they will chime in an help you.
Your 6.7ph, should be ok, without havin to flush, but your next watering, you should go in with a 5.5ph, maybe that will get your ph, where you need it, 5.5-6.5, like you already know, especially since you said your plant is doing good.
The reason I say go in with 5.5 is what Nebula says to do, and trust me she knows. GoodLuck

One plant is good for 2’by 2’space as long as u train her properly, and you got plenty of light,go with manufacturers recommend heights.im not a hydro guy but these are general basic rules to follow. I’m sure other’s with more information will chime in. Lol

Quick update i am only running one plant. Didnt think i had the space for any more then that. Which is why i decided to try Scrog and Got Feminized seeds.

[JediKush]

My Set up: 27x27x63 grow tent

2 300w Mars Hydro LED lights

2 4 inch inline fans 1 pulling in one pulling air out (have one on bottom and up top)

1 6 inch clip fan ( one the plant)

General Hydroponics 3 step nutes and use Hydroguard as well.

General Hydroponics PH Up and Down for adjusting and have PH and TDS Pens to check

5 Gallon bucket air pump and stone

Temperature at plant level stays steady at 40% humidity and and 77 degrees.However i have my lights set to 20 on 4 off and the temp generally drops to 72 degrees.

Also running ScrOG due to my limited height and have been following LBH's Scrog tutorial for that.

Genetics: Sour Diesel Feminized from Crop King Seeds


Current Status: 2nd week and topped when the fifth node hit about 1/2 inch and plan on topping one more time before flower.

Questions: My biggest worry is my lighting. Do i have enough for my grow space? And should i look at something different for my next grow?

What Kind of Yield can I maybe expect?

How far should i keep lights from plant? I started at 30 inches from seedling and havent adjusted.

PH is 6.7 and steady and plant looks good. I know optimal is 5.5 to 6.5 and plan on bringing down when i do a resevoir change here soon.
Is this enough of a difference to worry about?

I appreciate any help or feedback and am open to answering any questions.

Thanks
