How much room should i leave between my screen and light box? I know they are going to stretch and I am prepared for that I just want an estimate on how tall the actual bud will be.
I'm using cfls (4-100w replacement soft white 2700k) in a air cooled light box so they can grow right up to the glass and not get burned.
Some basic info to get an idea:
I have two 3 gallon pots and have been lst'ing and topping to keep them small.
Using perlite/mg soil (like it or not)
Nutes : generic mg food, will be switching to ff for the flower.
One bag seed and one fem mix from white label
been vegging for about a month

Any good estimates?

Respect The Herb - With the CFL's you keep them close to the canopy. Take a peek at they countless CFL grows on RIU and compare for a good representation of what you can expect. There are many CFL screens done here on this thread that you can locate with some time researching.

Topic of Discussion - Gravitropism

In light of recent talk of vertical scrogs, U- shaped screens, V-screen, stadium, etc. I wanted to get a bit more in depth with where the idea that these are less effective in comparison with horizontal (flat screen), is derived. I explained previously in discussion that gravity has a key role in plant growth and thus vertical screening works against effective use of this controlled "stress" if you will. Without understanding these controls it is hard to argue for or against particular designs. I would like to post some information for the advanced members and for those who are interested in learning about the mechanizes that dictate directional growth and how it relates to trellising. These controls are known as Tropisms.

Dr. Ambers [FONT=&quot]It is my strong conviction that the technology or the applied science in a field of knowledge can make efficient progress only when pursued with sound understanding of the fundamental science upon which that technology is based. Progress in technology without a foundation of fundamental science can take only two forms, I believe. First, minor improvements of applications or treatments which are already essentially known can be made by technology alone; and second, occasional (though rare) accidental discoveries of new applications or treatments may be made. Practically every major advance in agricultural technology in the past half century has stemmed from fundamental scientific information.

I understand that, and will be moving the lights with the growth of the buds. I just need to know how much room to leave between the top of my growbox and the screen. I'll keep looking around, i've read that i should leave myself 8-10 inches for the but that seems a bit optimistic. Or is that about right?

There are other factors to consider, length of time in screen before flowering etc.

I would leave more room than you can use, say a few feet. This gives you ability to "grow" and install hardware etc.
I suspect the best way for you to determine this however is simply research others who have used similar environmental controls.

Here's a little reminder of why it is very important to take care when training. The flower sight where this cola grew must have been damaged during training, most likely by being pulled back through the screen (my apprentice has been punished accordingly). Because the wound did not have time to heal before flower, it essentially molded this nug from the inside out. Luckily I was able to salvage quite a bit of the cola, but if I hadn't noticed this until next week the entire nug could have been lossed to mold. I noticed this because about a dime size spot on one of the nugs seemed more mature than the rest, you can see it in the first pic. I've seen this before growing outdoor so i just went ahead and cut down the cola and starting breaking it a part. Considering how big this nug would have been in two weeks I probably salvaged about 35% of it.

I had that happen once before Robert but the bud never made it above the screen, just 1/2 way and was hidden. Unfortunately, it was back in the chicken wire days and the bud grew , engulfing the wire. I think it was the wire, being galvanized or whatever, but those metals or gases "rotted" that bud pretty good. Looked just like typical bud rot but wasnt as powdery when you crush it in ur fingers. Good point about using care though, I've snapped far too many arms in my day but its a risk u take when you keep the screen as low as I do. Yes, they are often repairable with a good splint but had I taken my time, let the arm bend slowly, it would have never snapped and would have never stressed the plant like that and now I also introduced the slight risk of that plant hermi-ing

Key point here is,....take your time,....the plants arent going anywhere, any time soon
