Critical Mass Tree Grow x 2

.... ive never been more impressed in my life...

Heath, Can I ask a few q's about the critical mass grow?

1. Regarding veg, what was the size of the area used to get those 2 plants to that size? I'm assuming they must not have been vegged in the main room due to the plastic wrap.

2. Secondly did you have the veg farms recirculating or just on the air pump drip ring?

3. Are you still using the same old 8x6 space or is this a new area? If it's new what size and how far do you hang the lights from the centre of the farm?

4. Why have you changed the feed pipe from the side entry 22mm overflow pipe to the 25mm top feed through the pebbles?

5. Are you still using 40mm overflow pipe for the drain and how many drain outlets per farm?

cheers m8

Hi KS,

1, 6ft x 8ft

2, I recirculated, I just rigged up a 1 inch feed pipe off a pond pump and ran it 15 mins every hour.

3, Its new and its now 9 x 6, The bulb is roughly 1 to 2 ft away it gets a bit tight near the end though!.

4, Just to make it easy to set up, there is no yield advantage but its easier to simply have a pipe feeding from the top rather than through the side.

5, Yes I still use the 40 mm pipe and have two outlets per tub , one isnt enough as you have to slow down the feed. On my last grow I had one individual plant which weighed 44 0z and I struggled with 2 outlets due to the roots restricting the flow. My next tree grow will have short lengths of 40mm pipe which will join a 4 inch soil pipe to improve the return back to the rez.

what strain are you going to run?

hi heath im sure you dont come back here and look at old post but its worth a try.i was wondering if you might be able to give me a diagram on your room set up for the critcal mass tree grow. thanks heath

Hi iculikeit


0 x 0 x 0

0 = bulb x = Tree

is that what you mean? if not ask away.


Heath

yes that is what i was wondering thanks. i was looking at what you posted o x o x o and i was wondering do you think it would be any better doing 3 trees like this using the same watts

.........o
.......x..x
......o x o


one last thing i say u on another site. you did a vertical grow where you ran a sog i was wondering in that grow how far away where the three rows from each other top to bottem

I really like the idea of a tree grow, does anyone still have the other diary of this grow which includes all the information of constructing this setup?

I have an area of 16ft length by 14ft width, 6.4ft height and would like to grow 6 plants like this using 6000w of HPS/MH instead of the stadium grow which I was considering.

I thought this way I eliminate 200 plants and replace with 6 and achieve a simmilar yield. Granted it will be be anything like heath's I understand that but it's less risky than growing 200, less butterflies believe me.

I also noticed that you let the plant stretch quite a bit, they look quite large for 6 weeks from clone. I have no problems with getting them to stretch, use halo or I can place light further away so in effect it is less compact and they reach for the light.

Would that be down to strain or was that delibrately undertaken in order to make the plant a monster and stretch it like that. I get about 4inches a day using halo with new clone sites forming also within 24 hours of use. Usually around 5-6 ft at 6 weeks without trying to stretch them, not sure if this is good or bad?

I am also interesting in what medium you were using, will reread the thread again as I might of missed it. Im thinking rockwool 3inch cubes and clay pellets with a 40mm flow 24/7? perhaps originallu starting with a 1inch cube and transplanting in 3inch cube.

Also interested on bucket size, 5 gallon pots perhaps, would you have worked up to that size assuming im right, starting at say 1 gallon size and slowly increasing bucket or pot size?

Would also need to know what size pump i would need and make if possible, not sure on size of resevoir or pump to control tree's, cannot believe im saying tree's. Would your pump be able to handle 6 tree's and if so what make is that and is it quite? Them piston compressors make a hell of a racked last time I had a bubble bucket setup way back, even tried burying it in sand in a box to reduce the noise.

Any information on setup anyone can find will be great, will start construction as soon as iv found what im looking for, soz for all the questions, im blaming it on the Chronic.

Heath I pretyy much run the same sytem as you and was wondering if you could take a look at my journal and see if u see anything im doing wrong/right. really wondering about the pump times. Do you run 24hrs a day?

what strain are you going to run?

does nobody read anymore?

Wow thats great i am planning to try this method and was wondering if you could give me a few pointers?

where both plants in 1 aqua farm or in two?
How tall were the plants after 6 weeks of veg?
what kind of nutes did you use?
and finally, where did you position the verticles throughout veg and flower period?

I would be very geatfull if you could help me with these

Oh Ill be using recon by dna

So you don't use co2, in all the pics that I'm seeing I don't see how your keeping the room cool. Are you running ac or just air exchange???? I currently have a 12 x 6 with a liquid coold hydrogen burner and a ppm 3 and consideering ditching the aircooled dual grozilla and super sun ii and running the bulbs naked like you. I'm running the australian autopot system in cococoir. Current plant stock is super skunk 6' tall and 6' wide with two hps over top aircooled and two naked hps 400 in your configuration. Just got lady bugs but plant is fighting off infestation. Do you super crop your six footer's to provide your monsters or do you just let them roll all the way through veg? Hope this finds you well and your smoke smooth!! Later!!

Hello heath
i've been looking for the critical mass plant but can't find any, i've found a critical haze but thats it, are they the same thing?
cheers

Look up mr nice seeds. he has the critical mass seeds

what is the deal with vertical grows? do you get more yield or do you just like to be different?

Would you ever consider writing a tutorial or something. Seems like its hard to get answers out of you, share the knowledge.

the first 2 trees. you had 1 400w to veg them. then you had 3 600 w to flower.

you used a drip system.

what were all the roped or ties ?

the strain was critical mass? does that smoke well?

Hi bestgrow,

I spend quite a lot of my time "sharing the Knowledge" its not difficult to get answers most of them have already been answered in this thread. I post on many other forums so its not a case of me not wanting to help its simply a matter of time, I apologise if I gave the impression that I was holding back on how I do my grows.

To summarise the tree grows:


The ties are to stop the branches from snapping under the weight of the buds. The same effect can be had from throwing a net over the plant at the start of flower and as the plant grows through the net it is supported. I prefer tying them up though.

1, The lamps used were 600 w hps growlux bulbs with lumatek digital ballasts. The bulbs are hung vertically without shades, this allows the bulb situated between the plants to basically do twice the work of a bulb in a shade as all the light from the bulb is used.

2, The plants were vegged for 6 weeks from a rooted clone the original clones were in a 1" rockwool block which had been rooted under an ordinary household florescent tube, before being transplanted into the aquafarms.

3, The nutrients were used at a EC of 1.2 throughout veg and flower, I keep on veg nutrients for 2 weeks into flower to help prevent premature yellowing of the leaves at the end of flower. I let the PH drift up from approx 6 to 7.

4, The system used is basically a fast flowing dripper system, I have found the higher the flow (within reason) the better the results.

I know I will have left something out but I promise if any of you have a question from now on I will try to answer it if I can.


keep it green


Heath

Wow, thats perfect! thank you so much for the details. I am planning on turning 2 into 6, so what do you think about this design...

The size of the boxes are irrelevant. the green are the plants and the blue is the light. Any thought?

anyone, do you get more yield when you dont use a reflector?

You get better light usage, so you get more yield per watt if your growing trees. But some people swear by SOG for most G per watt.
