I would start flushing hj at week 7 or so. if herijuana is estimated at 8 weeks its probably gonna take 9 maybe 10 to finish properly. If i have no idea how long its gonna flower, i'll flush shy of week 8. I've only grown a handful of different strains but none have finished earlier than 9...

What was the estimated flowering time for your seeds? If i haven't grown the strain before, I usually start my flush one week short the estimated harvest, usually week 7 or 8 of flowering, and I flush until they are ready to harvest

Are you filling your res with a nutrient solution or with plain water? if you fill your res with a nutrient solution the ppm rises because your plants don't use 100% of the nutes you give them. So the nutes that are not used start to build up

you don't need to wait for a scale. you can start mixing in small amounts of salt, like 1/4 teaspoon, into the alcohol. if the salt dissolves completely, add a little more. keep doing this until the salt does not dissolve when you add more. the salt dissolves into the water in the iso alcohol...

very cool, i remember doing an experiment like this in high school lol. The stores around my house sell 99% iso for only like 30-40 cents more a bottle, but next time I can't find any i'll try this.

you guys should check out Nasa's Astronomy Picture of the Day. I can spend hours on that site. http://antwrp.gsfc.nasa.gov/apod/astropix.html If you click on the calandar link near on the bottom of the page you can see APOD pictures from 1995-2009

I agree and I posted a link to htg earlier in the thread.

because I'm stoned... I'm using my laptop as i drop a duce

yup, they just sell replacement bulbs. Some carry low wattage hps (70 or 150 watt) that are usually sold as security lights or spotlights; these lights have built in ballasts and come with a bulb. I recommend just going to the local Home depot and have yourself a look or buy online

you totally hijacked this thread lol

you can get bho from wet leaves/bud but it works much better if you dry your leaves/bud. also with wet material, the extractor gets clogged easier and may cause a blowback I use all the leaves, trim, and popcorn-buds from my grows to make bho. let them dry for 4-5 days until they are crispy and...

if you buy a mh bulb you'll need a ballast to run it. you can get an 150w mh or hps system for pretty cheap and it will work much better than a flood light. http://htgsupply.com/viewproduct.asp?productID=53025

i feel your pain lol I had one hell of a time trying to get my master kush clones to root. try to keep everything sterile. I use a little rubbing alcohol and clean my razor after every couple of cuts. just keeping things clean has upped my cloning success rate *edit...

I never had any luck with bubble cloners. I think its because i can't keep the water temp down. Anyway, I've grown a few super silver hazes and have always had a hard time cloning from them, it always takes a couple of days longer. Try cloning with peat pellets or rockwool cubes, they have...

I had the same problem with one of mine because the the lid was warped a little. I bought some binding clips and put them around the rim and all of my leaks stopped. check them out, i got a box of sixty for 5 bucks at walmart...

Yeah, those booster fans are shit. check out s&p inline-fans (http://www.hvacquick.com/spfnconfig.php?fm=td). they're very quite and relatively cheap, i have a 4in and a 6in and am very happy with them.

I had a chromium crusher and i hated it. it always got clogged up and mushed my bud together into hard chunks. also the metallic finish started to chip off. I have a xxl sharpstone grinder now and i like it, plus it was pretty cheap (I get quite a bit of keif from it too). I suggest spending a...

what kind of inline fans do you have and whats their cfm?

I've looked at a couple of these "tricks" (I tried using a banana peel during germination) and none make much of a difference. I think that it's more of a wishful thinking kind of thing. If you don't want to mess with sexing and pulling males, just buy some feminized seeds.

you can do that if you want. I've done it and none of my ladies were stressed enough to produce pollen sacks. It took a while for the sex to show on a few of my plants and it ended up taking a lot longer than i expected. Also if you veg long enough (~6 weeks or so) they should start to show...
