there are many factors to get females even out of feminized seeds...FYI (another whole story...I did a thread)

We have had so many of this same question over and over and over. I bet I don't have to go 2 weeks back in the boards to find 2 or 3 of the same thing...OK I have ranted.

the point is; some of you newbs, don't realize...there really is no such thing as growing hydro in one container...even if you have one plant in a container you are still in need of flower containers as well as veg containers...

i.e. You could take the tub you are talking about and put 4-6 clones in it, but from seed; you can't put any more than 2 in a tub, even that bigger one if you are starting from seed. The roots will become a problem before you can sex and move all of them to individual or 2 to a tub after sexing.

Now you said you made a homemade drip...In my room I veg 2 to a tub in drip. I just got thru growing out some SexyOrangeSkunk from seed...I started in rockwool, then I put them all in netpots filled with hydroton and placed them in my homemade ebb and flow propagation trays. Once roots poked out of netpots...I set 2 to a tub in my veg room. I was gonna do some drip, but I decided to use DWC,on these SOS, due to the difference in size of the 4 plants and the fact that I had tto restart my perpetual coning program...I take 4-6 clones every 2 weeks now...anyway. I placed these SOS plants and 1 fantasma(AK-47x) in 5 gallon buckets to flower. I just can't get away form the size these suckers get in 5g buckets. Now how many tubs do I need???

So you see what I am getting at? When you ask how many plants can you grow in one tub? Just one tub? One. peace
