    WHAT SIZE WATER PUMP SHOULD I USE FOR A 45 GAL RESEVOIR?

    A bigger hose on the outlet won't reduce flow. It may appear to be less because that pump out of a 1/2" hose will have more pressure than through a 1" hose but the 1" hose will flow more water. The only thing that will reduce the flow is if your head height increases or you reduce the outlet...

    Humidity in flower. How worried should I be?

    Thanks for the input. I've got two clip on fans keeping the canopy gently swaying and one underneath to stir up around the pots. It's also been raining for days around here so I'm hoping that slows soon. Sounds like if I start seeing a max above 65% I should pull out the dehumidifier though.

    Humidity in flower. How worried should I be?

    I'm heading into week 2 or 3 of flower and as expected my humidity levels are rising. I'm finishing this grow out in a closet tent but will be moving to the basement to a dedicated space after this. Currently temps reach about 80F during lights on with humidity ~45%. It drops about 15 degrees...

    mars hydro 600ts vs vander 2000w

    I wouldn't bother with the blurple. If you have to wait to save a little more for the Mars Hydro I would definitely go that route.

    LED that markets it's actual wattage draw?

    ^^^ What they said, and to add to that, 2/3 is a good rule of thumb when comparing like to like fixtures as far as quality goes. A top of the line LED system will replace a 400w HPS in a shit reflector with proportionally less wattage than if you're trying to replace a 1k DE with a well designed...

    1st Timer, CMH/LED, multi-strain autos. What could go wrong?

    Happy 420! We are at the end of week 5 and fully entering flower! The growth over the last two weeks is amazing to witness as a newb. Hell, now that they are into stretch it's crazy how much they grow every day. I pulled the deformed Blackberry to free up some room. 4/19

    31 Days. How do they look?

    Thanks for the input. I topped two, did a true FIM on one, whoops, and tried very slight LST with the others. Since this is the first grow I am worrying more about keeping the environment right and getting watering and feeding down. Have to get a yield before I can worry about maximizing it...

    31 Days. How do they look?

    My first time growing. These are an assortment of auto's. They are 31 days from the seed being placed in a peat pellet and 23 from being transplanted to their 3 gallon pots. I'm curious if they seem to be where they should be and how they look, other than crowded. Lol.

    1st Timer, CMH/LED, multi-strain autos. What could go wrong?

    4/1 I decided to try topping a few as they seem to be growing well after recovering from the heat stress. The one BB still looks like hell. 4/5

    I’m probably a jerk for asking...

    Running at 50% percent usually refers to dimming the fixture after it is built. That being said, most builds are designed such that, even when run at 100%, the diodes are not actually being driven to their max current for efficiency gains.
