Yes that makes a lot of sense, thank you very much. Keep rambling for me. Hey if one were to do a 4x4 1 plant perpetual scrog. 1 flower and 1 veg room. What is the least amount of light you could you use for the veg room? Let's say for example the strain needed to be moved to flower when 80 -90% of the screen is full and you have been vegging into the screen ( screen and everything on wheels). Could you get away with using a 400w mh to veg 80-90% of a 4x4 scrog? How about 250w mh with a kick ass hood? How about if you wanted this same 4x4 veg room to supply 2 4x4 flower rooms but still only use 1 400mh for veg? Could you just pack the 4x4 with more plants so that you don't have to fill up the screen 80-90% since more plants would cover the 4x4 in flower more quickly. For example have 4 plants in the 4x4 veg room instead of one. 2 plants for each flower room. Or maybe it would have to be more like 6-8 in veg? To use the least amount of light possible during veg would it be better to not train into the screen during veg but grow plants tall and then when ready to flower, bend them over and throw a screen on? I'd really rather not run more than 400 in veg if I can get away with it and not sacrifice too much quality/yield.
I couldn't see using much less than 400 watts for a 4x4, but if ya want, give a 250mh a try.
400 would probably be perfect if you are trying to fill a screen as you'll likely still get some stretch from your plants with a 400.
I would definitely rather go with 4-5 plants in a 4x4 myself to cut down on veg time.
It could take a long time to fill a 4x4 screen with 1 plant.
30-40 days is all it would take with 4-5 plants.
A lot of your Scrog training is going to begin after flip during the stretch.
I have decided to put on a Screen late and bend down some plants, but that's definitely not ideal.
Your plants will branch out more and fill in the ScrOG in faster if you put the screen on earlier.
The faster you get the top shoot bend down under the screen, the faster all the side branches will shoot up to the top.
When you get those down under the screen, their secondary shoots will start to shoot up.
With two tents or rooms you could kill it.
Not sure if I'm reading you correctly, but if you have a couple tents, just start one 6 weeks after the other.
( I did read your whole post, I swear. I didn't catch the Scrog on wheels thing though, That's killer. Disregard the rest of this post about moving lights, lol. Much easier to roll a scrog right into the room.)
When you pull your flowering plants, replace them with veg plants and switch the lights from the flowering room to the veg room/ veg room to flower room. That would be a good pound or more every 6 weeks.
If you have 3 tents/rooms, just do the same thing. Just keep replacing your harvest plants with veg plants, and swap the light out.
That would give you a 30 day veg which would be pretty good if you were using 4-6 plants in a 4x4
Should pull a pound or more every 30 days running like that with 3 rooms.
My very first real hydro grow was a 4x4 and I pulled a pound and a half with 1200 watts.
I also had root aphids, spider mites, temperature issues and had no idea what I was doing with PH and Feed, lol.
