The problem with certain hydrohuts is that they are apparently made with some sort of vinyl or problem IN the vinyl that apparently causes some sort of gas or emission that THEN causees suffocation in cannabis plants. That link is to an announcement by the Hydrohut people admitting the issue and offering to fix any defective Hydrohat. Included in the announcement is an e-mail address so he can contact the Hydrohut people and have his fixed.

If you read the thread very carefully he pretty much says that everything that went into the hut turned yellow.....and whenever something came out of the hut it improved.
Classic symptoms old chap!
Weedhound Reviewed by Weedhound on . IT ALL WENT WRONG at first they were green, and now dying. it a little difficult to explain, but heres my best to do so. the three that u can see that are already pretty dead looking were brought to me about 2 1/2 week ago for cloning ( there all suppose to be grape ape) after pulling 50 clones i threw them under a air cooled 600 mh in a 4x4 hydro hut. my 50 clones turned yellow and dyed. after a few days my leaves started going yellow, thinking it was n deficiency i feed them with foxfram grow big. but nothing Rating: 5
