wilma 20 pot grow and no room:(

i've got a wilma 20 pot. 15 just cheese growing and there 19 days into flower.
wow there bushy lookin healthy but it's overcrowded in my 1.2x1.2 tent and was jus wondering if any expirenced growers had any advice on maximising my yiealds as i've read that being overcrowded could cause them not grow to there full potencial..
ohh and hello really glad 2 be apart of this forum
any tips and advice at this stage of my grow would be appreciated...ty

if you went straight from rooted clone into flowering you should make it, but if you vegged them first they become to large. How long did you veg them for ? and any pics ? I'll be able to help more with that info

hay.. i vegd 4 3 1/2 weeks then switched the lights and there from seed. i'll try get some pics up. i've only gt a moby camera atm and wen the hps is on you get them fuzzy lines on your pics.
there looking healthy thou. but was worried that with them being so close that i mite not get the best bud development. i dont know.
i'm using a 600hps and know that it penetrates so far into the canopy.
the biggest are at around 30 inchs and they all have buds forming.
i'll get some pics up asap...cheers 4 replying
