There is no way i can make the beds bigger now Kanga, it fuckin near killed me digging them to 600 mm deep as it was, maybe i could put some logs around them and make them higher and do it that way. As for growing them to monster trees, i said to bushy i didn't want that, i want to bend them over at 8 foot then let them go.
Hi mate, don't become disheartened, if you've dug them down to 600mm (double what I thought) you should be OK by putting logs around them and building them up. The only reason we made this observation is because where your plants are now at this stage in the season, with the MMWW genetics in the CC; you're looking at 12 x 12 foot plus plants & probably more like 15x15 But tying them back, giving them a haircut etc. I think you'll be fine - still some hard work ahead mind you. I also believe that plants tend to flower a bit earlier and stay smaller due to hole constraints.
Another thing with the MMWW particularly is that it loves fertilising and some extra chook shit around the very edges of the hole should pay dividends when its flowering time.
This is a lesson I learnt last season, as I had a monster MMWW 16x16 that didn't have much in the way of hot ferts and the smoke was pretty mild compared to the knockout smoke from the same strain that Kanga bought to the table. Even with that scenario, I was able to blow some veterans away with the size, smell and taste of the colas.
One thing on your side is that the Nimbin Purple is generally pretty early flowering, because it's 50% Shit, which was selected for its Afghan leaning traits. This should reign the size in a bit - hopefully
Anyway If you can build them up Il think you'll come through this with flying flowers.
