good info here. If you want to grow multiple plants in a tub...you must wait until you have a sexed female Mother plant, then do it. Root tanglement is a real problem when growing more than one plant in a tub...you might be able to sex clones in time, but I doubt it. 1st...clones cannot be taken until plant is at least a month old...by then there will be roots everywhere. If they tangle then you have to cut the males out and that will leave dying organic matter in your rez as well as choke out some of the other roots...

And, as mentioned above...You can grow 1 or 2 and get just as much yield, probably more with less plants. goodluck
latewood Reviewed by latewood on . Number of plants in an 18 gallon rubbermaid I'm growing from seed and I want to have at least 2-3 females in a rubbermaid dwc under a 250w hps and some cfls. Could I start with 6 in an 18 gallon tub? I will be sexing from clones as early as I can. could I start with 8 plants then cut the males? I'll probably be scrogging it to get good light coverage.
