We have clones available to us... blue dream. We are planning to start with about 25-30 clones and pick the best ones....sound like a good plan?

bluebloodletter

Sounds good to me, but how many are you going to choose to grow to harvest?

phorbinsbuds

Well, not entirely sure about that. I think growing about 15-20 would be sufficient with 200 watts right??

bluebloodletter

Okay, you mean 2,000 watts, right? 2k is enough for 40 square feet. If you are planning to grow 20 plants at one plant per square foot, you'll only need one of the lights. Or you can give them more space. Or you could just grow all the clones. Or you could grow them out for mothers and have 160 plant Sog to flower Ok..Ok...I'm getting excited...sorry.

Don't apologize, I appreciate all the information. So really we should be growing closer to 40 than 20 straight through until harvest right? Can you give a comparison in yield with the 40 plants, and then the 20? If we give them more space, and obviously the less amount of plants the more light each gets...does that usually equal out or no? Sorry if that sounds confusing basicly my question is:
Do you compromise yield by growing less plants or does the fact that you give a smaller number of plants more space and more light per plant, will that equal out to a similar yield as it would have been with the 40 plants?

bluebloodletter

that depends on the amount of light and space you want to use.
That's a broad question. You will of course get a much smaller yield by growing half the plants, but it will be more than half. Square footage of canopy is very influential in figuring yield IMHO. This is based on the observable fact that a densely packed SoG, will outproduce a ScroG(requires extra veg time) of the same square footage but fewer plants. It will outproduce but only slightly,say 15-20% even though 4-6 times the number plants will be used. My best guess for the yield differential of 20 and 40 plants? 75-80% more? There's really no way to know without just growing them.

phorbinsbuds

We have a ten by ten area so maybe we will just do the full 40 plants....thanks for all the help

bluebloodletter

No problem, will you be journaling it?

phorbinsbuds

most likely, yes... i am a bit weary of posting alot on this site but i have been doing it from a diff. IP address than my house... i think it'd be a good idea to journal it..

Built the box today, turns out no AC will be available to pump into the attic which worries me a little bit. We built a floor, and put two by fours at the top and will be buying some heavy cloth tomorrow to line the outside of the box with. Any suggestions? As we rumaged through the attic however, we found various pieces of wood that were already there that definitely indicated the tenants prior to us were growing in the attic as well. I am a bit concerned about the temps up in the attic, but we will cross that bridge when we get there. Thanks for all the help guys, will be doing a journal to keep yall posted.....

Blue- you said you did attic grows in the pacific northwest.... how were your temps? We are not even a mile from the ocean, and are hopeful with enough ventilation we can keep it under control
