Hi
Tejasdirt here
I joined this forum JUST for this thread
Not not new to growing, I've at one point or another have dialed in a 150 hps mini fridge SWC scrog,
And a ppL floresant server case mini Hempy v-scrog to produce 3-4 oz per run
I have had 400 watt soil amoir grows (too much heat)
And now have a 250 hps custom built (to fit in a small in use closet) grow cab with 4 inch inline and scrubber.
I have been trolling ALL forums about LEDs (even got sucked into buying a 20*1 red that screws into a normal light socket for $150 4 years ago) Live and learn.....
So I am asking for opinions.
I have the above mentioned 250 hps cab 18 x20x45 inches (will need to be retro fitted)
And
A amoir whose flowering side would be 18 x18x 70 inches ( needs to be completed out)
Due to family emergency that took me unexpectedly away for a few weeks and a burnt out exhaust fan, ALL my genetics dried and died.
So now have 4 feminized grapefruit seedlings in a Rubbermaid tub veg chamber.
I have just purchased a mars 48*3 reflector I was going to use for my veg amoir, and get a mars II 400 for the bloom side, due to space limitations.
Do y'all think the marsII would be overkill for either of spaces? ( the amoir will be a v-scrog, 3 square feet growing area, while the custom cab would be a flat scrog )
Is more better like Hps?
Or would the 48*3 reflector that I just purchased and just shipped (AMAZING) be ample for flowering in either of those spaces?
Any opinions would be great!!!
Thanks
Tejasdirt

I've been following this thread for the last little while, very impressed with the results! I'm planning on purchasing the 1200w MARS 2 for my 4'x4' flowering tent. Is the standard spectrum still getting the best results?

Will Vicky send me shipping info once she has tracking number? Just need to make sure she has my friends address since I am out of state till mid October. Thanks Sara.

Hello everybody!
I have a question that i hope that somebody can answer. I have just finished my grow of some plants called supercritical autoflower from greenhouse seeds. On their webpage it stands that yield is up to 800g/sqm. I grew about 24 plants on a 2,88 sqm space, in a grow tent that is 2,4x1,2m. I used 2 pcs Mars II led grow 700w from the begining to the end, that is aproximately 500w per sqm. On my big surprise when i harvested and dried everything my yield was less than 15-25 grams per plant,, my total yield was 280 gram, that is less than 100g/sqm. IHave done everything else correct nutrients everything, so my question is, did i use too weak lamps for that space?? maybe 500w/sqm is to little? Because i dont want to give up on mars II, i was thinking maybe if i use 2 pcs mars 1200w next time on that space that will almost be 850w/sqm. Since i am a new grower with led lights ( this is my first LED-grow ) i hope that someone could tell me how much of led-wattage is required per SQM in the flowering period to get maximum yield.

happy for answer

Hi mate i read on this site somewhere i cant quite remember who wrote it but i know it was some one well respected on here that as a min you want 35w per square foot. Maybe someone can second it??

I forgot to add this is for flower period its a bit lower in veg period not sure on the numbers though.

 

[sativacat]

35w per square foot sounds pretty low. Im running a Mars II 700w in a 2.6" x 2.6" tent. That works out to about 100w per square ft.

That sounds like the bare minimum suggested/required for CFLs in a stealth grow. A proper CFL grow would be at least 100w veg/150-w flower, ideally 350+ watts, but buying a comparable LED will use HALF the power, and produce BETTER plants. Which is why I made the switch

Those CFL wattage suggestions don't apply to LED, as you need more height in the grow area since LEDs need a lot more distance between the plant and light.
