2023 Spider Farmer SF-7000 x 2 1st grow

[SoOrbudgal]

Sorry about your shit neighbors i have really good ones on either side of me. They know i grow outdoors in summer. But my place is really tidy and we all take pride regardless of our incomes. I don't go to overboard with plants but it will stick towards the fall rippening. No complaints and no busy bodies. I get more visitors in summer here an my tent is in the only spare bedroom and gets the room very warm without the air on. I do better in fall temps indoors and humidity is better. Gets really dry indoors during summer in the house. Like now, I'm not running the central air yet just opening windows allowing breeze but it's hot an dry outside like in the 90's not good so early folks are barely getting veggie gardens up do to late winter an rain just 2wks ago .

I was trying to keep RH in the low 40's late flower SoOrbudgal and it was this that pushed the temps up. I could maintain 45/46 RH at 80⁰F but any lower on the RH and temps slowly rose if ambient was above 65⁰F.

A lot of the heat in the room was produced by 4 very inefficient 80W LED flood lights I used for corner fills. I only have an air-conditioner rated at 1.6kW cooling that only drew 480W at the plug, smallest available wall AC that are readily available.

The room is currently getting a make over. It smells of rat piss, is filthy and I need to get rid of my original lighting rack that effectively lowers the ceiling height by a good 10" and also move my storage rack and spare equipment and nutes out of the room and I had mounted the two SF7000's way too close together

All of that will take me a few weeks as I'm mostly out of state for work.

Growing outdoors here has proven really difficult over the last 4 years and now it's impossible with my neighbours who are doing all they can to make my life as difficult as possible.

New layout coming soon..stay tuned

Thanks for the report Bluey those are some strong " beams " in that series. It gets above 85f in my 3x3 with 250watts i won't grow indoors for much longer.

Well update on the lights

They work well

I recommend them if you have the ceiling height.

I ran the drivers outside of the grow room. Managing heat and humidity became an issue in late flower but was only running a very small AC to keep temps down. Upgrading that before it gets hot outside.

Day 34
temps were too high..dropped temps
Lights too low. Raised them to 29.5" from 27.5". Currently dimmed at 60%
Increased room circulation air flow
Ready for 2nd & 3rd top..waiting for a bit of recovery first.

Lights on. VPD 0.8 and will rise once temps increase and AC kicks in.

5th nodes now reaching for the sky...topping soon.

I've got a 240ltr water tank that I'm filling only to about 120ltrs...automated watering 3 times a day atm.. I will switch to two after topping...it water's for one minute through 3 mini sprayers I can adjust for flow in each pot...that lasts me about 6 days. Currently getting 10 to 20% run off.
I will give a pH'ed flush of plain water at least once every 5 days...about a 10ltr flush, and I keep neuts at about 60% of that recommended

Thank you, I'll check it out.

......So the real question is what's up with them plants in trash cans, you going for it?

......

The reason for the trash cans is that I know with the 405nm early on and all those 5000k white LEDS I can fill those pots completely with roots early on and reap the rewards at end of harvest with enormous yields if I can get my light pretty even across the entire canopy...yes it takes over 4 months, it needs more veg time to get length on the lower down colas so I can pop them up into the canopy....the reds help with that at flip too I'm told.

I'll post yields in about 16 weeks time, let's see

Driver and board details...about a 9ft power cord

[Bluey]

To add to that they can use 1 of 3 different diode manufacturers..I specified the Osram version and they were the most expensive but only by a few dollars...I questioned them on that and they sent me photos of both Osram reels and batch and bin # stickers....I have no reason to doubt them and didn't inspect the diodes under a microscope

Last harvest I ran the reds 12/12 250 to 400mm above the canopy...300 to 350 seemed to be the sweet spot with my highbays and floods at about 600mm above....buds got that big, larger than my forearm and fist they all got mould..I had 8 of them big ones on each plant. They all died before reaching maturity. I managed to save the medium size and small buds but had to harvest too early.
i was planning to turn the reds off 2 weeks ir thereabouts before harvest time but never got to that point.

This grow I will run them from flip again through to about the same, 12/12 is the current plan...if main sf7000's are at say 700mm above canopy Ill keep these reds at about 640mm above canopy and see how that goes.

I'm only running the booster reds as everyone says the SF7000's are a bit light on in the red compared to the deep blue/violets and I already owned 5 of them.

I tested the lights before using them in the first grow and they were drawing 30watts a piece so as described there.

This is where I bought them. No issues. https://m.bavagreenled.com/sale-1387...agreen-ir.html

Lots of DIY there friend, I like it! So the real question is what's up with them plants in trash cans, you going for it?

One of my favorite things about this hobby is piecing and parting things together, ever time I come into fall it's always a crunch to get a thing done so I can flip. My irrigation is a hodgepodge of timers and pumps and things but all of the rooms environment controls work on a trolmaster thesedays, I love my grow but interweb control allows me to love vacation at the same time.

Iv got gavita uvr bars but haven't used it yet. Them GC 680s I run dip into uv range and I can tell, its one of them thing i "did get in" before the flip 3 years in a row. Lol. Im lookin at IR for a up coming project, you've run your IR in flower already? Short blast? Sun up/down?

Control panel and RJ11 ports for daisy chain dimming and a control switch to act as master or slave.

Pretty sure the dimming switch is standard 1-10v but I read somewhere in the specs it's 0-10v...no biggy..this light won't be used under 25% I wouldn't think.

[Bluey]

The driver is a MOSO driver...it's rated @ 600w output and on paper a very good driver.

MOSO specialises in driver's for outdoor usage exposed to the elements, street lighting drivers etc and they are all made to that high standard of IP67...The cabling is first rate although the connectors are not the highest standard, I think they will do, time will tell.

EDIT: The control board has a really nice dimmer knob, but the RJ11 ports do not have any weather sealing and are no way rated for any moisture ingress. They do not seal when connectors inserted nor do they come with covers if not being used. I doubt the switch or dimmer is rated but this needs to be brought to Spider Farmers attention. Don't spray water mist anywhere near that control panel.

The cable between driver and light fixture is about 2500 or 8 & half feet long. This will allow me to mount the drivers outside of the room if heat becomes a problem.

The lights are running at just under an indicated 40% dimmed...and the light fixture doesn't appear to be running any higher than ambient of 26⁰C, although they would have to be. The driver is warm to touch, I'll measure it properly when lights are back on for a few hours, but I'm guessing around 40⁰C to 45⁰C..

With my light setup Im at a height of 720mm to 800mm above sprouting fourth node (100 to 150mm high) and getting 290 to 330 ųmol/m²/s directly above sprout and going 360 to 390 right down the middle. Today is about day 18 since the seeds went from paper towel to coco....I haven't mapped the area for flower but can run everything at up to 100%...I'll be moving a light or 2 and a pot or 2 to balance the lighting over the remaining females.

5 year manufacturers warranty on all MOSO drivers.
