Okay, so I am transplanting my plants from their 2 inch rockwool cubes to my hydro, so all i'm doing is basically putting them around those water-rocks inside a plastic cup. My plants are just over 2 weeks old. I have been reading that you are not supposed to water the rockwool too often,but...

Okay, first timer grower here with a basic question, is this the best way to set up all my timers? on/off Light/exhaust 18/6 Space heater 6/18 (when lights are off) *optional Airpump - 24/0 Nutrient pump - 15 minutes every 2 hours, once during the lights off cycle fan -24/0

24 if Temp isn't a problem, i believe.

No, it's in a cold basement and the temperature has droppped to as low as 54 degrees before, but usually just to like 57 or so... I know it shouldn't go below 60, so that's what i meant.

what about at night time? I have been having temp problems, so i should probably turn it off at night, right?

Okay guys, first time grower here, got a bunch of instructions at the hydro store and a huge amout of equipment, forgot all the insttructions and figured out everything except one or two things. Here are myquestions: First, should i have 3 air stones in each of my 3 tanks, and should i just...

cool, i moved the light up 3 inches... By the way, I was referring the distance between the lights and the canopy, to clarify

Great, well i'm going to bed and will be up in like 4-5 hours, so i'll have a gander in the morning and see if there's any signs of stress, and if not i'll continue. You guys have been amazing, thanks.

I just realized that chart was for a sodium and i've got a MH light, are they roughly the same?

Dude, that chart is amazing, thanks. I think my temp is fine considering i have this huge empty closet (16 sq feet) and only a 400w, and a fan, and a HUUUUUUUUGE exhaust ( at least it sounds huge lol).

Okay, so one seedling may be as close as 6 inches.... As long as the temperature is good, then i'm okay? Then why does everyone else have so many temperature problems??

Glad the subject caught your attention, because i'm assuming most would be screaming "no!". However,i just added a 6" inch high powered exhaust fan, plus a humidifier with a fan RIGHT next to the plants, and the plant temperature seems totally fine for the seedlings. I have a thermostat in the...

i was 95% sure i had the answer, lol

When should i turn the fan on? It's at 12 days since i planted them.

that's what i thought, thanks bro. I just installed my exhaust, and it works BEAUITUFLLY! Now I just need to hook up my hydro set up and i'm done.

Hey guys, installing my fan and was wondering if it should suck air out or blow it in??? I'm guessing suck are out of the closet?

Perfect explanation, thanks. :)

Hey guys, so I noticed since putting my seedlings under a 400w and a fan, the humidity has been going 30-40% quite frequently, and the rockwoll is drying out remarkably fast. I was going to add a humdiifier... However I was told that tons of people need dehumidifiers as well, what's the...

it's a standard 6" diameter metal tubing (like you'd have for a furnace) that curves to a square piece.

Oh, also, how do i know which way to put the fan in. Plus, I have like 2 3 feet of room on oneside of the closet which is very concealed, but then i don't think i could install a carbon filter. does anyone know any ways around this?
