I am one week into flower. I am doing the spider mite CO2 poisoning right now. This time I am leaving exhuast vent open while I taped everything else sealed shut including the intake vent and door with some duct tape. Using a online calculator to figure out correct regulator flow setting to...

Yes, I am talking about spider mites. I am trying to kill them!

Sir, I am talking about poisoning spidermite. Sorry for the confusions.

Hi everyone, Just couple of questions about CO2 poisoning with a CO2 tank and regulator: Should I leave exhuast vent (fan and light off, of course) so that the CO2 can raise and push out oxygen through exhuast vent when CO2 tank is running and building up at bottom of sealed grow cab? With...

Hi everyone, Should I leave exhuast vent (fan and light off, of course) so that the CO2 can raise and push out oxygen through exhuast vent when CO2 tank is running and building up at bottom of sealed grow cab? With this first grow, I taped both intake and exhuast vents. But I think to tape...

Hi everyone, This is my frist grow using a bubbleponics system and is first week into flowering. The tank water levels might drop enough soon which will requires me to add some more water before weekly draining. Do I just top off with just water without any additonal nutes? It seems like...

According to Roseman's tutorial on this website, use of UBV lighting during flowering will increase yield. Unlike Roseman's CFL garden, I am using a 600 watt HPS. Will I still benfit using UBV lights? Please let me know soon because this Friday is one week into flowering and I will...

I think I figured it out. I am having root rots! From allowing too much light in the tank for first three weeks and algae had attacked the roots. Now, I need to figure out how to save the plants. One plant's root is all rotten and already started to break off in pieces.

One thing that I noticed is, right after I added extra dose of nute last weekend as described above (4ml vs 8ml per liter), two sets of leaves on one plant turned dark green over night while other leaves on the plant stay yellow or lime green. See posted picture #5. I really think the lack of...

I just looked at that on-line CO flow rate calculator again, actually it says that it will take about 40 minutes to bring my grow closet up to 10,000 ppm if I set my CO2 regulator flow rate at 1.0 cfh. I just left it like that for 4 hours without the light on. If I understand correctly, the...

I am using neem oil spray and it seems to get rid of the mites. Problem is that the plants still are sick and probably was before the mites.

Huh? Need to be at 10,000 ppm to kill mites, correct? I have the closet sealed shut. Including taped intake and exhaust vent while the CO2 posioning. Already done that three times in last two weeks, with the light out for four hours. I do not have a meter but according to on line calculator, I...

Hi, Thank you for your time and here are my growing problems: The plants always have been lime green or yellow since I got them about 4 weeks ago. I think they was dark green when I got the clones (one God Bud, rest are Sliver Haze) so I am positive that I am doing something wrong here. I...
