Well my seeds have arrived from a land far, far away and I'm ready to start them soon. I am going to crack them in water, then place in rockwool under fluros (or should I put them straight under a 600W HPS that is way up high?). Then grown in tubs with clay balls and a recirculating system. My question is...when the seedlings have filled out the rockwool with roots, do I just place the rockwool into the clay ball medium or do I have to remove the rockwool? Jimbo

As the title suggests..im just wondering how often i should water when ive mixed 30% perlite into my potting mix...its seems to be dryer alot quicker and bcause the perlite is mixed in...does that mean i can water even when the substrate is still slightly damp? any tips? Cheers, Flon

How do you keep your airstones at the bottom of your bubblers and reservoirs, and stop them floating to the surface? Is there anything toxic in plywood (the glue maybe?) or is it okay to use, in the nutrient solution, to hold the airstones down? All replies appreciated! P.S. like my new Avatar?! Cugel.

I've just planted a clone outdoors by heeling it in...(planting it at an angle) so that the stress of bending her down horizontal to the ground will be much less. https://cannabis.community.forums.ozstoners...si&img=4470 Already hardened off for about a month, all I did was add ammendments to the soil and plant at an angle, putting a good hand and a half deep soil over the root ball and trenching the soil under her so that she isn't laying on the soil. This girl was way too healthy to fit in the flower box. More pix in a week or three. She should be ready to harvest in late Sept, to mid Oct.

Hey all, i took some clones off my plants that were 4 weeks into flower, 6 days ago. A couple got abit droopy and they sort of recovered but now i've got yellowing patches on the leaves and tips. Is this because they havent rooted yet? I used jiffy cubes with clonex and im sure the cubes are not under or over moist. They have been foliar fed every 2-3 days with a week nute solution. Temps have been a little high 25-30C and also using a heat mat. they arent looking well, help would be much appreciated.

I planted my seeds (after leaving in damp tissue over night) about a quarter of an inch under the soil and as the light(250watt hps) was only about 6 or 7 inches above the soil it dried out the top layer of soil after 18hours of lights on and when i watered them to make moist again the water pushes the dry soil off a bit each time so that eventually the seed was very close to the top.Well yesterday i raised the light about another 3 inches higher and went to put the seed a little deeper in the soil but it had sprouted and i had the light on and the root got about 4 seconds of intence light before i coverd it up again. Is this going to be ok?Or would i have shocked it?Al…

bought a prop dome and it has holes at the bottom, i dont need the rockwool swimming in water do I? Or can i just spray the top and bottom when they drying out?

Is it still necessary to aerate the water if using an aeroponic system..? just seems since the roots are hanging in the air it wouldent be required. any help.?

I came across this article at this web site.. I would appreciate some feedback before i go ahead and buy a timer. Thanks.. http://www.intelli-cycle.com/information.php Growing with an 18 hour Day/Night Cycle The Theory The theory behind the 18 hour Day/Night cycle is that during a normal 24 hour light cycle plants will usually acheive high growth rates peaking at 100% capacity during the first 50 - 60% of the day. The growth rates will then diminish rapidly and the last 20 - 30% of the day acheives minimal growth. So by reducing the length of the day we are triggering an increased growth mode where the growth rates are at their peak for the majority of the day. Th…

Im sure it was another site that i read about this,. but i would like to know if anyone here has heard about doing this. Some people were using grow nutes the week before final flush/rinse of the root/medium system to reduce the amount of phosphorus (i think thats the name ) being consumed by the plant. (Nasty stuff for us apparently) I think this is an effort for a better quality smoke. Normaly i would use flower nutes & flush with straight water for 10 days or so. For the 10 days prior to that should i use just grow nutes or should i use flower nutes? I have posted nearly the same question on this other site ive been lookin at but no answers yet. Lookin for some…

I read this on another forum (not as good imo) and wondered if there is any truth to it? I am running at 5.6 all the way through, but if it's true....??? Jimbo

I read to soak rockwool cubes at ph 5, what do you do??

I have had my plant under 12/12 for 2 weeks now. I noticed yesterday that she is a female,...but she has red pistoles. It is only the lower part of the plant upper part has no pistoles yet. Is this a problem or stain related?? I can't quite get a good pic as my good Cam is getting fixed ATM. Any help very much appresiated. - BTW It is just a bagseed grow for my first go. In soil under 500watt cfl
