My setup, a homebuilt box 60 inches tall (5ft) by 44 inches wide(4ft) by 22 inches deep. Ive got 3 fans, an intake an exhaust and a circulation fan. A carbon filter for smell, but thats besides the point. Im one week along... and not sure what to do...
This is my firstgrow...
I am planning on using a Screen. I wasnt sure what would be best...
This is where I need advice....
I have a 400 watt MH/HPS MH for veg HPS flower.
SHould I use the screen to stretch out the branches so they recieve light, Top them and flower below the screen
OR
Veg until Ive tucked and weaved most of the screen up..??
Help?

Im not the biggest expert on the matter but i believe it really depends on the strain and how much it stretches. I would say flower once your branches start coming through the screen because most plants will stretch a lot in flower. Depending on how much space you are working with you can top and train below the screen before flower to get a wider canopy with less plants.

Finish the screen entirely in veg before you flower.

Hey punk that makes no sense they double in size whren u flip it to 12/12... i wud run out of room

double to triple in size... Double is underestimating the plants ability IMO.

Doing a ScrOG can be difficult if you don’t know the characteristics of your strain. First off, I hope you have females growing (from clones or feminized seeds), you don’t want to have to pull a male out of a screen.

Your main concern in your box will be controlling height. YOU DO NOT WANT TO FILL UP THE SCREEN BEFORE YOU FLIP TO 12/12, you will be fucked if you do in my opinion. You will continue filling up the screen for up to 3 weeks after you flip, while the plant is going through the stretch phase, basically until true buds start forming. Since you don’t know how much your strain will stretch, I would recommend filling up the screen about 50% and then flip and continue filling the screen until buds start forming.

You didn’t say how many plants you are growing, fewer plants mean more topping before you reach the screen, more plants mean less.

You didn’t say how much grow height you have (the height between the top of the pot and the max height the plant can grow without getting burned by the lights) but with a 5’ high box and 400 watt light I’m guessing about 2’. I would recommend setting your screen somewhere around 8 - 10” from the bottom of the plant. You don’t want to run out of height.

Make sure you have good air flow in there, the screen will get dense and the plants will be more susceptible to insects and mold.

Ya i got 4 in there.. that helps.. thanks... i got shiva skunk and blue dream? does anyone know how they like to stretch? Also, after i transfered them into their new containers, they were clones, the edges of the leaves are yellwing/ what loooks like burning.
I have a premix grow formula, rainbow mix, i mixed in, and i did not put to much.
Im thinking i might mix a little bloom there their next feedeing just to give them more nutrients but idk what the problem is
Yellowing and edges kinda dropping down?
anyone help?

Are you in NorCal? The NorCal Blue Dream is a real stretcher, at least 3 times bigger when you switch to 12/12. You'll need to be careful with this one.

Don't know about Shiva Skunk.

Yellowing and edges drooping, could be overwatering but can't be sure.

thanks man... that helps... but idk if its overwatering cus its been prettty smooth i can tell when its dry i poke my finger in the soil. Maybe it was just the transplant shock.. but now im not thinking so..
recently i noticed the leaves becoming more droopy, and also i noticed 2 yellow tiny spots on one of the leaves... what could this be???

so the tips are still yellow and bottom leaves kinda yellow as well. not fully yellow. Also near the top but not at the top, there are a few spots on the plants. idk what this is. i dont see any bugs and its only on like 2 fan leaves. I also dont feel like the plant is thriving how big are they suppose to be after a weeek and a half. they were clones i transplanted.
I was thinking maybe to add some more nutrient a little bit of bloom even though they are in veg.
I added rainbox mix grow to the soil so i thought it shud b good. but idk. thanks
