I want to sound proof the door completely. BLOCK almost all of the sound coming out of a room. How do I do this? I was thinking building a wall made out of wood and put it in front of it. And then stuffing pink fiberglass insulation between the wood and the door. Seal up all cracks with this...

I need a way to cover a large DWC - what can I use that's cheap and works? I was thinking sheet metal? Plexiglass? Wood (can I paint it)??? Worried about it getting wet and the repercussions from getting water on it or humidity over 2 months. Maybe use chicken wire and place net pots in...

stupid stupid clones. they are wilting. sometimes they turn into mush (too much humidity) other times they turn into dried out crackers. right now they are turning yellow and brown. once the roots hit they tend to flourish. is it possible to OVERSOAK rockwool? want to just keep it in the...

4,000 watts of light. 10" fan - 790 cfm (230 watts). 8" ducting. DWC grow. There will also be an A/C and a Carbon Filter in this place but I have not included it in the drawing. Is this circular design really bad?

i was going to build it. 2x4s, ply wood (or similar), and tarp.

4000 watts + fans + a/c + hydro set up so about 5000 watts 12/12. for a 2 bedroom apartment... how is that???

so that's the question. how many watts does it become suspicious? is there an amount? what's borderline?

8'x8'x6"(depth) DWC with 128 plants. SOG style grow. Immediate clone to flower. 4 1000 watt cool tubes. 1 8" fan with carbon filter. 1 10" fan 790 cfm to exhaust lights. either 1 118 watt air pump or 4 18 watt air pumps? which is better? same price. what do you guys think of this set...

What were they? anyone figure it out? were they all the same kind? or all different? like if you got 10 seeds were they all the same?

Want to force it to flower and finish in 8 weeks. Current set up - clones set at 24 hours then it hits 12/12 for 8 weeks. I was thinking: clones set at 24 hours. then for 2 weeks 11 (hours lights on) / 13 (hours lights off) or even 10/14? then 6 weeks at 12/12 Any other suggestions? Maybe...

had some napkins where i wetted it and put in seeds. Sprayed daily. I open today and 3 of the 4 seeds sprouted but ALL have black mold dots on it??? What can I do?? HELP!?? Are these seeds gonners? spray in hydrogen peroxide? bleach? just spray it with water (to get the most off)???

no light leaks. like 3 months into flowering....

i thought oscillating fan was just for strong stems?? wouldn't a fan just create more heat and just move that heat around?

thanks guys. really helpful repped you all.

Like it doesn't seem to progress. still looks the same after 2-3 weeks. like it flowered. but the trichomes are NOT changing any more colors... i think the plant is just dying... like some parts that aren't getting any sunlight are turning brown and drying out...

it feels like a 95 degrees in here. is this horrible?

will that 12" cool the lights and do the Carbon filter? or what? will 1 424 cfm cool 4 1000 watt lamps?

so i cut one of the two. it had small buds with long hairs already growing right by the intersections of each branch. i cut it anyway and trying to root them. don't know if it'll work. what's moisture stress??? btw?

Getting 2 fans. 1.) one for Carbon Filter - clearing out a 10x12 room. 2.) one for cooling down 4 1000 watt lights (all attached, air cooled, sealed)
