THG, Really more like two cabinets side by side w/ common wall. One veg, one flower. Run duct through common wall into a tee. Extend one arm of tee through top to exhaust. Inline fan will draw air up through single riser connecting to both cabinets via tee. Each arm of the tee must have an...

THG. Origional question was: How many times per minute or hour should air in grow cabinets be exchanged? 4u2sm0ke responded: I exchange air every 2 minutes. Working back I derived: rate / vol = cfm / vol = cfm / cf = m. m in 4u2sm0ke's case is 2 or 2 minutes. PuffinNugs suggested: "youll...

Stoneage. Example: width x length x height = cubic. ie. 52" x 31" x 83" = 133796 cubic inches. 1 cubic ft = 12 x 12 x 12 = 1728. 133796 / 1728 = 77.4 cubic ft. Vortex fan 4" = 172 cubic ft per minute. Therefore Vortex 4" would flow at a rate of 172 / 77.4 = 2.22 times per minute. In other...

4u2sm0ke, Thanks. That makes it a load easier. My current ducting is 4" and moving to 6" would be a real pain. Cheers.

Fellow growers, I'm in the process of updating my ventilation equipment. How many times per minute or hour should air in grow cabinets be exchanged? Have 2 cabinets, 1 veg - T-5's (35 cubic feet), 1 flower - 600 hps w/ cool tube hood (90 cubic feet), for a total of 125 cubic feet. Planning...

Sixx, I was under the impression that a nute solution too strong for your plants would cause a drop in ph, and a too weak nute solution a rise in ph. I couldn't give a good explanation for the chemistry behind this phenom, and someone here will be able to give a better explanation if needed. Cheers.

HF, your attitude:cool: and humor :D will serve you well on this forum, and your results will speak for themselves:eek: . Good luck w/ your floating grow! ps. The Hemp Goddess will not steer you wrong, and her results are second to none. Cheers.

Don't forget that styrofoam will attempt to float.:eek:

Question here for all who do not adjust ph into the 5.6 - 6.1, with 5.8 preferable range. Talking hydro here, but soil growers have near the same max and mins for their nutrient uptakes as well. According to the charts in the sticky linked below, most of the common nutrients will be taken up by...

hxxp://www.marijuanapassion.com/forum/showthread.php?t=57109 Looks like one of your bugs. Cheerrs.

Smeg, how hot is your cabinet? I just went through an extremely hot - (100+F day, 85 +F night ) three week period, and the bottom two or three side shoots of each plant withered and dried up. As soon as the temps moderated, only 93F day, 80F night, the problem seemed to dissapate. I tried an...

Just went through the same thing w/ some BLZ bud seedlings. At 5-10 days they developed yellow central vein. Battling some high temps 95+ F daytime, and 85-90 F eve temps, so I re-calibrated PH instrument. Sure enough, ph too high. Running hydro, so I adjusted ph and all new growth was fine...

RB, Your Mandala grow looks tasty. I have grown out the Satori from seed a few times and like everyone here who has experienced the result, you will not be disappointed :D . I experienced two different phenotypes. I preferred the shorter, denser, more indica looking (very spicy, piney, large...

OGK, Does the actual quality of the THC degrade?, or is it the quantity of THC left on the leaves? If the actual quality declines, then most of the hash makers out there are degrading their bubble due to freezing of trim.:eek: So, should we store our trim in a 'wine celler' type...

It has taken UK and Dutch seed retailers anywhere from '10 days' :D to '5 months and still waiting' :eek: :eek: for the packages to arrive. I would say the average is 2 weeks. The 5 months and still waiting package was confirmed received in the US, but tracing from here is fraught with...
