You can always drop some mylar from the ceiling (A little wall) to lessen the space/increase light distribution. It's cheaper to close in your space to work with what you have than to spend on upgrades to cover it all... unless you already have the schematics done and ur mind is set. Either way it seems like it's gonna be a killer grow. Good Luck with everything. :eyesmoke:
very good advice thanks man and i really hope so dude.
I'll try get a journal sorted when i get set up:eyesmoke:

Going to start one myself. I still have enough brain cells to post journals on my grows currently.. just lazy lol I have one in week 8 flower and 4 clones in a 2x2 in week 3 of flower. I kept them short and flowered quick to work with my tents. I have 1 plant in a 2x4 and wouldn't have been able to fit another in there if I wanted to.

What about 4 x Spider Farmer sf 4000's in a 8ft x 8 ft tent
is that sufficeitn enough for Co2 supplementing :cool:

I've fallen in love with this light just shame about the $600 per unit price tag o_O
The boards won’t get as good of coverage as the bars but they will work. You can get Kingbrite 480w boards for half the price of the SF TS4000 or 480w bars for about the same price as the TS4000.

4 480w fixtures are the minimum wattage I would recommend for 8x8. That gets you 30w/sq ft.

Personally I would go with kingbrite or Meijiu over Spider farmer, same quality for less.

I have 4 mars hydro ii 900w panels 100 LEDS replaced only blue spectrum as i think these burn the hottest (460nm + 440nm)
All other LEDs seem in good order apart from a couple which i will also replace.

My grow space can either be 6.5ft x 6.5ft( 2mx2m ) or 8ft x 8ft (2.4mx2.4m ) I haven't quite decided yet but
i think the smaller one will accomodate the mars 900w x4 lights better for full coverage in flower.

The lights have been through 3 grows but i have no umol/par meter to test their current output.
According to MarsHydro 15inch is the sweet spot for best even coverage.

I'll be running everything top notch:

RDWC 9 X 9-GALLON BUCKETS + 1 EXTRA FOR RES
18 PLANTS
WATER CHILLER
RO WATER
CO2 TANK (800-1200 ppm)
ADVANCED NUTES
SCROG + LST
6.5FT X 6.5FT TENT
ETC..........

SO PLEACE HELP ME.................Do I use my 2015 MarsHydro 900's or Opt for better.
I'd say use what you have and add white lights. Your blurples are better suited for veg than flower. Don't rush into buying, there are lot's of lights to consider. Many are satisfied with Meijiu lights from alibaba, but don't expect great warranty service. DIY strip lights are very popular here, check out some of the builds.

I'm kinda warming to the strips now tbh and if i DIY around my 4 mars 900 panels i should theorically hit my 1000+ umols :roll:
If i do then win win for the co2 supplementing

I can't thank you enough for this post.....insiring my creative side....i love diy and electronics.
I'll be 100% giving it a try so if you imaging a 2m x 2m tent and 4 mars hydro 900w panels positioned centred in each 1sq meter space.
any space around them i will try and cover with strips....some work i bet but HOBBY is the name and LEARNING is my game.

Thanks again.

Ill try and take a sketch of what i may want and ask for your opinion fi youve done it yourself ?

Personally I would upgrade..... Got some good suggestions already. Not mars though, longevity issues still exist. Jumping through Social media hoops for some free lights works too I guess.


I'll recommend mars hydro when both @The Dawg and I are finally invited to the staff BBQ in China! Fuck yeah

@1212ham

Please reply to my image post bro i sketched up and tell me if this is actually do-able ?
And also ask why you say implement more white light.
My knowledge is more mixed spectrum in good retion to one-another shouwld be good.
what spectrum will these strip lights put out in the specrum band ?
will they be more close to hps rather than metal halides high blues

WOULD THIS GET ME 1000+ UMOLS if i keep the lights close as i can to the canopy ?

Yes, they would work. Not sure what your fixation on co2 is about but they would do the job
My fixation on Co2 supplementing is that it boosts up 30% more yield if utilized under perfect optimal continues conditions i.e.
*higher air temp
*higher light intensity (evenly ove canopy)
*controlled humidity
Controlling the environment as perfectly as i can.
Lets say i'm some what of a (if i do it - I want to do it right kinda guy) especially this time around...!

My last 3 grows were just OK and im not pleased with my results even though the avarage joe might have been.
BTW don't even use wilma 4 pot systems their tiny 4mm feed lines clogg up so bad i didnt even realise and without doing regular cleaning
as the novice i was my grows suffered during late flower and end results :wall::wall:

This time around im going as automated as much as my budget will let me and also to the best of my ability.

RWDC
10 x 42ltr(9 gallon) storage pots......each 9 storage containers housing 2 x 14cm net pots.....so 18 dUTCH iceberg lettuce ladies spaced
The 10th 42ltr stroage container will be my res and placed outside of the tent for each access.

I'll try and draw another disgram and upload tomorrow if i get chance :eyesmoke::joint::weed: I MAYEBE BUSY H@H@

I'll make another sketch tomorrow of a 8ft x 8ft space see if you feel I'll benefit more.

basically my goal as youve probably gathered i want 1000/1200/umols/par evenly over my canopy
So Co2 acctually works for me., peace out for now :bigjoint:

Much as it pains me to say it, 4 x Mars-Hydro TSW 2000 looks like the best fit for that odd size
If you go 8x8 your costs go up but you have many more options
I maye just go up to 8x8 tent for more options and room for scrog and i think the 18 pladies would appreciate the leg room :eyesmoke:

First, unless you’re getting 1,000 micro moles or more across your canopy the co2 is a waste. I suspect those lights aren’t giving you that. The 6.5 x 6.5 size isn’t well suited to most lights ... especially the newer bar/strip style fixtures. You should probably look at QB style fixtures.
You can certainly grow with your existing lights, but start saving for more efficient, better spectrum options
well i guess i should go with 8ft x 8ft and thats most likely what i will do more room to work inside and more options like you say ?
