Im looking to setup a DR90 tent in my bedroom with a 600w hps. Im trying to work out ventilation. There is only a vertical slider type window in the room(with one of these similar old-style vents on it -...

Im having a problem with either rootrot or brown algae from day 1 on this run. Its dwc, res temps are 68 and plenty of DO and non-organic nutes, but the clones used had the problem before being added to the system and I havent been able to get it under control, veg is ridiculosly stunted. When i...

Im looking to run a strain that is - single main cola - indica (doesnt have to be 100% indica, but no full sativas) - high yeild - short flowering - easy to clone They will only be vegged maybe a week after rooting then straight to 12-12, and I dont want them going over 2-2.5foot. Will be...

Im running 2x 600w hps under 2x diamond reflectors at the moment, but there isnt enough spread with those relectors, the outside plants barely get anything at all. So I'm looking to get a larger reflector for more spread. I was looking at the Magnum xxxl hood, but most people say dont run...

Ive been looking to add some sort of carbs to a DWC grow and have read a lot about some companies using molasses as the base for a lot of Carb additives and a lot of people just say use molasses. However in hydro afaik, molasses isnt a good idea, I've heard it clogs up stuff and causes foamy...

I got a 120 Litre/minute airpump and im looking to power 12x airstones or diffusers. I noticed though there is 4mm and 8mm tubing size diffusers. Would I be better off going for a 12x 8mm manifold or a 12x 4mm manifold (bearing in mind if I use the 12x 8mm manifold I wont have to use a reducer...

Simple question, but i cant find a solid answer. Does acoustic ducting reduce airflow? If so, by how much %? I recently upgraded a 6inch intake to a more powerful fan, but it didnt increase the airflow much. Im wondering if i replace the ducting with non-acoustic ducting (without the...

Im trying to find some info on bomb seeds (im looking at berry bomb but any info on the breeder is welcome). Not much info on them just 1 or 2 thc bomb threads. How is the breeder overall? Any info appriciated, thanks.

Im running 2x600w sunmaster 7200k mh bulbs currently in early flower. At the end of the 2nd week of flower im looking to switch over to hps for a few weeks. But some people are saying Dual spectrum hps bulbs are better than just the standard hps. Would love to hear some feedback on this, has...

Just saw the following breeder - http://en.seedfinder.eu/database/breeder/Green_Hornet/ Anyone grow any of these before? They have some tasty strains, but I cant find any info on them as to wether they are any good. I was thinking of getting their Original Swiss Strawberry.

Im running 36 clones (un-topped) under 2x 600 hps's in a 31square foot space, they are in DWC. The strain is Afghani kush from next generation seeds. Currently they are in day 11 of veg and have great root systems and are about 5-8inchs tall. Im not doing scrog or topping/lsting, just...

I got 10 fems of Greenhouse seeds - bubba kush from attitude. It was in DWC under 2x600w hps 6 germinated. 3 were hermie 3 finished but were terrible (less than 1oz between them). Now usually I'd say it must just be me and my shit growing. But I also grew it alongside (some of the bubbas even...

How long on average does it take to get roots in a decent bubble cloner? I have 2 built and running at the moment - 4.7 gals tap water(water is ph8.2 and 100ppm .7conv from tap) - plenty of air, 2x 12" airstones in each cloner with its own 400 litre per hour pump, loads of bubbles - 2 drops...

My water from the tap is PH 8.2 and 96ppm (.7 conversion). Is it ok to use ph down in a bubble cloner? It takes about 20 drops to get it to 5.5 in the container im using, will that be ok? Will that have any adverse affect on the clones? even with the ph down the ppm only raises very slighly.

I had to pull a hermie out of a 6 site dwc container - GH Bubba Kush. I cut the roots out, but there is a possiblilty of some roots left (not much, a few inches) in the root mass of the other 5 plants. Will this cause a problem? My res temps are quite low as it is cold here at the moment (res...

My first time cloning. Im cloning in root riot cubes on a shallow bed of hydroton in a heated propagator. At the start I had a small bit of water at the bottom of the propagator, but it was leeching up through the hydroton into the cubes and the cubes were staying soaked. So I drained the...

Im looking to keep a mother that I can chop 50 clones from every 2.5-3 months. I was just wondering how many watts of CFL will I need? I have a 150w envirolight blue CFL. Would this be enough, could I get away with any less? The plant will be a bushy indica, hopefully keeping it to 2'-3' in...

I'm having a problem with 70% humidity, I cant get it below this during lights off (on 12-12) if it has been raining outside. Im using a DR240w tent with 8inch exhaust and 6" intake. Intake is on full and exhaust is about 70% (both on 24/7) with 3x oscillating fans on also ( 2 on 24/7 on...

I have a 6 plant dwc tub with 6 different strains. 5 of them should be fine as their flower times are roughly the same, but one of them is an auto. How can I deal with this? It looks like the auto will finish maybe 20days before the rest, but all the roots are tangled so taking out the auto...

Im using root riot cubes and a heated propagator and I was just wondering, do you have the cubes sitting on the bottom of the heated propagator or would you have to have them raised up so they are not touching the bottom(same would apply for rockwool cubes)? If so, is it ok to line the bottom...
