Mars 300w led

1 marshydro 300 can handle a single plant or 2 smaller plants. LST and scrog both good training techniques to gain a higher yield as both provide better light penetrating.

Eh if you are wanting to actually fill that 3x3 out with that one plant you will definitely need 2-3 lights... if you plan on just doing an average sized plant 1 light will work... but don't expect to have the plant reaching wall to wall and that mars 300 preform by itself.

Feel free to check out my journal to get an idea of the area they cover.

Yeah that'd work fine.

 

girl scout is auto , blue dream is not auto flower

 

Hard to grow autos and photos in same area unless you keep the photo in veg. 12/12 lighting will reduce autos yeild.

wow didn't know that 12/12 hurts auto yeild ( never done one ) so autos in flower you can give more then 12 hours of light ?

 

You can pretty much run it whatever schedule you want, but generally 20-24 lighting is best. I run mine at 20.

Correct

+1 to upinsmoke. I ran mine on 24-0 for 4 weeks and now tapering down to 20-4 reducing 1/2 he e cry 2-3 days. They seem to be reacting better to this schedule and got my preflowers. I still feel my plants are behind though.

Check out my first grow log:

First ever grow: How do the girls look?

 

I originally was running 24 but switched to 20 hours because it seemed like the plants were stunted. Once I switched lighting to 20/4 is seen a significant amount more new growth.

One for veg will work ok. These have very narrow spread so the light will only really give you good par reading in a 1-1.5 square foot area under the light. You can raise the light but you'll lose par. Two should be fine for flower in a 3x3 tent. I run one on for seedlings. Two on for veg, and three on for flower in a 2x4 tent, although 4 wouldve been better. Remember they only put out about 130w even though they advertise as 300. You typically double the light in flower as the plant is supposed to double in size. My new set up will be a combination of hid and led, got a 4x4 tent so I can start perpetual harvests.

 

I did 24 hours threw my entire Grow did great

1 mars is enough to flower 1 plant as another said .. 2 mars = better
