General Cultivation Q&A

I've was checking out my mates's recirculating system, which uses clyballs in orchid/net pots sitting in tubs, which in turn drain back to his tank. He was talking about the airstones he's put in these tubs and how they're supposed to help more oxygen get to the roots, when it struck me : why not pump oxygen directly into the tubs? Oxygen is heavier than air (specific gravity of 1.15 or thereabouts IIRC), which means the you could work out the volume of the tubs and inject a measured dose of pure oxygen into them at fixed intervals, which would displace the air iand increase the oxygen available to the roots by a factor of 4 or so. Have I discovered the secret to a mas…

hey, A fair few people have been asking for this thread so here goes. Ill try to get some pics when possible as usual . If anyone has anything to add feel free.... Canna/dutch master/natures own- 250gram compressed block (expands to 2 kg aprox) 5kg compressed block (expands to 40 kg aprox) 20 kg granulated bag 50 kg granulated bag With the compressed blocks you need to expand them into a large rubbermaid style container(50-70ltr). It takes about 30 mins and expands about 8 times. The substrate is too hot to handle during this stage but after a hour or so is bearable with gloves. The coco still needs to be cleaned throughly. To do this i use the largest pot…

My set up is very simple, I know nothing about what I'm doing so i'm just guessing as a i go. Set up consists of, 4 letre bucket (res) i have the water pump in the bucket pushing water out the hose. then water pipe then goes into a 8" piece of PVC about 1 metre long. ( i think this is a DWC setup?) then i've put cuts in the pipe where my pots are. the problem is that there no water pumping out the output pipe back to the bucket.... Do i need another pump on the output end? Or is the pump just not powerfull enough? thanks

Hi guys and girls. I have had two grows now with shit results. I have only managed to muster 2 oz each run off 4 plants under two 400w hps lights. I am convinced that i am useing a pritty shitty strain. I come to this conclusion as i have a decent set up and my plants seem very healthy. Based on this i plan to send off to spc and get myself some clones. The only problem is i have no idea how to plant them once i get them? As i have never been involved with clones b4 only seeds. so........ How far under the light (400w). What media? (they will b in soil eventually) What nutes/ hormones? any other suggestions? I really have no urge to kill $150 buxs. one last q…

I was looking up some seedbanks for no reasons, and I noticed some indica strains, that some seedbanks made a note:"If you have cooler dark periods while in the budding stage, can increase the "purple" colour" Anyone can give me more information?, is this possible on some indica strains, you can increase the purple colour on the buds if you made the dark periods a lot cooler? Thanks for your time Urbanhog http://www.gamers-forums.com/smilies/contrib/sp/chefico.gif

Can anyone tell me how deep MJ seeds should be planted in soil? How long does it take to emerge from soil? high_hoper

I recently had some clones sent to me that were rooted in Rockwool, it seemed to keep its shape better than grow wool and didnt stay water logged. I've just started to play around with growing from seed and I'm, trying to get a good foolproof method going. I like to see whats going on each day so I dont use soil and so far I'm not real impressed with the grow wool blocks that I,m using now......when I squeeze the excess water from them, they stay squashed and look like they could suffocate the newly emerged seedlings roots. Any one else use grow wool ?.....any tips ?

I have several healthy plants just placed into flowering (today) as they are quite short they contain considerable foliage: about 65 * 50 centimetres. As I have read that pruning should be done at this stage (before flowering) I was wondering which and how much leaves to prune? I have asked a friend who told me not to touch the plant, to let nature alone, but have read that pruning does improve yield. All comments and ideas ars welcome. Also I have been pulling a plant over to increase it’s exposure to the HiD which has placed a branch directly into the shade of the main stem. The branch has not shown any signs of discomfort even though it’s growth has slowed. Should I…

Hello everybody, I've just set up a recycling system using a pond pump to pump nutrients through polytubing with drippers. As this is not on a timer it will be on all the time, will this mean that the roots may get flooded or will it be alright as the water will drain through? All advice much appreciated Cheers Holyreality

I have a plant on the inside of a window in my bedroom and It seems to be growing slow, I have friends that planted the same time i did and there plants are 3 times the sieze of mine. My Question is...... At night time, I always put the aircon in my room on, and the unit is very close to the plant, could this be stopping the plants growth?

there are these things called dutch pots whcihc are being sold at grow.com for 455 bucks with light(400 Watt High Pressure Sodium light kit), 400 Watt UltraSun lamp , that's kinda steep. Should i get the normal kit without a light for 225 and buy flouros, or build my own one, Please Help crzc
