Yes, you can have a balanced pH in Hydro. I don't have to do anything to my setup except for every 5-6 days and the pH is always right on. I use the flood & drain method, so this may not work for you. I have a 5 gal bucket hooked up to my main res (10-12 gal) via a float valve. As water is...

You're talking about the flower tent right? thanks for the compliment. yeah, i would like to have the carbon filter up in the top, but with that daystar ac, i don't have enough room depth wise to fit it in there. It's a 4" can filter, pretty much the smallest one I could fine. I could build...

You can let it go and die off naturally, or you can trim off the yellow. If you decide to cut it off, the plant will recover (see pics).

Definitely get a fan. Having a fan in there will create stronger stems and overall stronger plants. you should always try to exhaust your grow room's air into a different room or area so that fresh air is always flowing into the room. If the air coming in is at 80+ degrees...well...might need...

You should probably cover that rock wool with either hydroton, aluminum foil, or something to keep the light off of it and promoting algae growth. How far away are your lights? R u using R/O water or tap? What's your ppm? 6.6pH is a little high, I'd bring it back down to about 6.0. The pH...

no problem. you will learn a lot, fast. the learning curve is very steep, especially with a site like this. good luck.

What's the size of the room? What light are you using now? As close as you can get your hand to the light and hold it for 20 seconds without burning is how close your plants can be to the light. An oscillating fan will also help cool it down. Ice will work, but it's a temporary solution to...

You'll want to run 18/6 (I run 20/4 personally) until the plants are as big as you want them to be. Then going into 12/12 for up to 8-10 weeks (depending on the strain). You'll know when it's ready by the hair's changing color and the trichome development (magnifying glass). Your plants will...

I would just be concerned about the height of the plant. I've got a couple that have been vegging for about 6 weeks and they are well over 2' tall. Not sure what LST is. You would want to get rid of that small table you have in your drawing for sure. Your going to be flowering some very...

it's a tent from htgsupply.com. it measures 20"D x 36"W x 64"H. I built my own tent for veg with pvc, duct tape and black and white plastic (see pic). It's much easier to buy a pre built one, but more expensive. If I had to do it again I would get a tent that is a little deeper than 20"...

no, males don't bud. they just develop pollen sacks that will eventually open and pollinate any females that you have around, thus producing seeds in the female plant. here's a decent shot of what your female pistils should look like. males=trash (or hash)... your pick. i choose trash.

here's my 400w eye hortilux hps flower of strawberry ice. plants are about 4-5 weeks in. I use GH 3 part with liquid karma. All hydro baby :)

your plants will have a mild smell while in veg and then a strong odor once they get about 4 weeks into flowering. you could just build a small carbon scrubber to attach to the "out" port of your box. You could also place it on the outside of your case to save space on the inside. Here is a...

you won't really need a fan blowing "into" the grow area. It's more important that you have plenty of air moving "out" of the growroom. Of course have holes where air can passively flow in the area from the lowest point (coolest air). Having an oscillating fan inside will also help to keep...

i've found that htgsupply.com has pretty good prices. you might want to check with your local grow shop (if available). my digital ballast doesn't make any noise, it's my inline fan and reservoir aerator that make the most noise. no experience with a/c units but i imagine (from the ones i've...

Hey verysexybob, nice post. quick question: do you water your plants at all during that last 72 hour dark period? Or do you let them just suck all the water that's left up into the buds? Thanks.

Yep, I have a video production business (mostly weddings) and own rentals. Burn all day everyday if you want to...except Saturdays. Not too good showing up on the job after burning some white widow.
