Hi growers. I am doing an indoor DWC hydro grow with two plants. One of them is a landrace Malawi Gold pure Sativa strain which has grown too tall now being about 6 weeks old. This is my 3rd harvest and the biggest problem I’ve had with my previous 2 harvests is that I wait a little to long to start flowering and my plants outgrow my tent during the flowering stretch.
I got a new tent which measures 48x48x80 inches. My MG plant currently is 32 inches tall from the top of the reservoir to the top of the plant and 47 inches tall including the reservoir. I have topped her twice for 4 main colas. I know that I again waited too long to start flowering, but that being said I was wondering if anyone had any suggestions on what I can do to control its height.
Is there anything wrong with simply topping the 4 colas back down to a more manageable height? I know leaving in the metal halide bulb for the first few days of the 12-12 schedule can help reduce the stretch a bit, but I doubt that would be enough because this girl is growing like a champ. Any suggestions would be appreciated.
