    Just bought a 300 watt LED marshydro I'm aloud to have 12 plants, looking for a reliable seedbank for autoflower strains. Anybody got any tips on how I can get the most bud out of a 10x5 room And one maybe 2 300 watt marshydro hydro? Lst? Looking to get maximum harvest in minimal days if anybody has any tips. Planned to use fox farm organic soil and 3 gallon pots for ten auto flowers and lst under 2 of the 300 watt LEDs. Any input out there?

    Hate to say this but .... Those Mars hydro panels will not grow more than one or two plants half ass. The stated " power " is false they are about 1/2 of stated power based on actual pull from wall. So you are ACTUALLY putting out about 155 each.

    The panels CAN do 300 but are built to " throttle " down as to give the diodes a longer life.

    I would say target a more manageable amount of plants to start - say 3 or 4 .
    This way you can concentrate on them easier than trying to juggle 12.
    Once you get things operating , you can start up a couple more , so on and so on.

    Autos are easy , plant and go. Once they pop they cannot stop. They veg only for a short period then start throwing pistils around day 35-40 ( typical ) from seed. The breeder estimates on yield , harvest time , size is a GUIDE ONLY ... Most perform better running a bit longer until they are mature , NOT on week you are on.

    Stateside :
    DC Seed Exchange
    The Vault
    and a few others ( look at seedbank reviews on RIU )

    Overseas :

    I buy 90% if my autos from here - I always got my shit from them .
    They take CC , and it is secure. It DOES NOT appear as a bad purchase thru card.
    I have even bought with my ATM debit ... You tell bank to open card to SHOP international . It takes less than 5 min. Then you are good.

    I ordered here OVER 15 times , never an issue.
    They have a huge selection , both regular , autos , hybrids , premium.

    Good luck

    Found a good seedbank how much can I get off two of the three hundred watt LEDs and a ten pack of autoflower seeds?

    Have to agree with BZ-at best, your Mars will 'grow' a couple of small plants. That's using both of them at the same time-there just isn't enough intensity to grow anything larger.

    Autoflower is smaller though than a photo period? What's best to grow a few autoflower plants

    You can always augment whatever led lighting you have with 2700K and 6500K spiral bulbs. 6500K during flower, replaced by 2700K when flowers start to appear.

    Yeah, I corrected it.

    10x5 room with 1 or 2 mars hydro '300's? Just so you know..they are not 300 watt panels..they are just called mars 300..they actually draw just over 130 watts at 110 volts. It's good for 1 or max 2 plants..but with 2 full sized plants..you need side lighting for sure. 1 mars 300 can cover about a 2x2 area. For a 5x10 room..fully stocked with plants..you'll need 2 600 watt hps's or equivalent in led's. If you add cfl bulbs..you want the blue 6500's for veg and replace them with red 2700's in flower. Someone else posted the info backwards.

    2 Mars over 2 or 3 autoflowers in 3 gallon pots would provide around 4-6 ounces of decent bud every 10-12 weeks. This would require a 3'x2' grow space; if not a little less.

    Have you checked out Viparspectra lights? Better pricing, same concept.

    Have you considered nutes,calmag, reflective material/tent, fans/ventillation, ppm meter, odor control, water source etc? The only way to make it to the finish line is to create the proper environment.

    Here's what I tell most new indoor growers. Good lights, Good genetics and absorb as much knowledge as you can before you start. Looks like your going for high yield, so do your research on lights and pick something large enough for your grow space. Also sounds like you want an LED that is cheaper in price. Check out Optic LED for affordable, high par led lights. If you want large coverage for really cheap, go with HPS/MH but in the end that option cost you more with energy cost. RESEARCH RESEARCH RESEARCH !!!
