8-7-07 Day #49 of Flowering. Cab Temp: 77F RH: 40% Nutrient Temp: 75.6F PPM: 1200 pH: 5.8 Hey there, It's been a while since the last post as I've been very busy. I know you are probably anxious to see some new pictures so here they are. The bud sites are getting very plump and we are very near harvest. The grandaddy purple strain is not known for its high yields but more for its potency. Yesterday we took a trip down to San Francisco to renew or medical script and also pick up some grandaddy purple at the clinic there to see what ours would have to compare to. Anyways, the pictures that show full shots of the plants are good examples of what topping can really do for you. Rather than having one large cola at the very top of the plants that hog the majority of the light, we have several smaller mini-colas that branch out from the middle and get virtually equal amounts of light. We are right at the point where some of the leaves are starting to yellow and die. To answer some of your questions horrorbusiness: yes, you can use what you linked to for your grow. That is actually what our grow turned out to be since our drippers aren't working too well lately. The bubbler system's water level needs to be just below the net pot for the entire grow. When the roots drop down they will just be suspended and dangling in the nutrients. You can go to the hardware store and buy a sanding bit that basically burns holes in plastic very well, or a regular drill bit works. As far as doing nutrient changes we have two extra buckets that we place the entire mesh pot into just like it were another system. The roots are fine to dangle in the bucket just don't let them sit too long. Happy growing!
