im going to grow about 30 plants in a greenhouse in a raised bed, the ammount of light atm is about 11 hours (9 direct) and by the time it finishes about 12.5.

1)how far apart should i space out the seeds.
2)how soon will the males show?
3)any advice would be great

Height wont be an issue mate, your grapefruits are taller. Tallest rocklock is just over 30" from top of the pot, smallest is 17" from TOTP just might be a little bit bushy for a cab with other plants in with them, gotta watch for shading although your probably use too that with ya bubblebombs. I'm hoping to fit at least 12 in this cab and i cant do that with these but something like grapefruits i probably could. Still a fucking sweet plant all the same def one id do again 12/12

the only one ive done is ultra skunk, only used enviros and a couple of 70 watt hps in cab, great plant even in those conditions, fat cola, sticky, dark, easy to grow, hates lst....all my choices are 7-10 flowering and mostly fat cola types.....big genetics.

10s a little too long for me try to keep as many as poss close to 8 weekers, looking forward to trying this ultra skunk myself sounds a great one for a 12/12 sog grow.

I started these about 5 weeks ago and since then they have been under 2-23watt 2700k cfls and one 14w 6400k , also I threw in a crap 52w? led panel just for the hell of it.
The plant on the right is a mister stripey tomato clone and the rest are my "Esel" strain.
everything seems to be doing well but I was curious if anyone has done a 12/12 under a 1000watt hps and if so, how far away did you have the plants? I have plenty of room in my tent but the closest I can get it to the light without disturbing the other "main grow" is about 18" ....is this too far? too close?....any ideas are welcome

So I'm just germinating 3 x Barney's LSD and 3 x Barney's Tangerine Dream. I just have one LED panel at the moment, but plan to buy another in 10 days. The existing one is just finishing off a Nirvana PPP, which has around 6 weeks of flowering left. I'm toying with the idea of just doing them 12/12 as that's what the PPP is on, but I'm a bit worried the yield just won't be there. I'm not in a rush to harvest, so wondered if you guys could comment on the viability of having seedlings on 12/12 for a week or so, then going to standard photoperiod. Would they start the flowering cycle and go past the point of no return, or would it be possible to let them 12/12 for a week and then switch to say 18/6 or 20/4 and then revert to "veg mode"? I've only grown a few times, so apologies for the noobiness of my post!

Dont know many that grow that way on this thread were all indoor guys n pots and shit. Both questions tho are gonna depend on strain so when it comes to spacing i would just be guessing, if your doing multiple strains then chuckem in pots and atleast you can move em, once there in the ground thats were there gonna stay. As for show sex 2/4 weeks after 12/12 again depending on strain.

Makes out his product can go toe to toe with hps so think ill give it a go, he'll know if it doesnt thats for sure and so will everyone else lol.

Which thread would that be? I'm chasing a second LED panel now, and could do without the import taxes I paid from the USA last time, although I fear the "already here" version will be even more expensive including taxes + shipping.

Gonna give it till me grapefruits are done comming into week 4 now of 12/12 so 7/8 left if i remember right then ill probably get one of thos leds in. I'll do two grows one hps one led with grapefruits and see what happens. Your cab is about the same size of mine roughly rekon youd be able to get 8 rocklock in there...just, be a squeeze tho. Im after girls that stay within there pots so i can do some 12/12 SOG grows partly the reason for a 30 odd strain grow, see what works with the 12/12 sog. Thinking grapefruit 12/12 SOG would be good to start with, might do a mini one and see how it goes but could imagine 40 stuck under two 600w........now that would be nice.
