i have a 4x3.5ft tent - last go around i did '7' various strains under '2' 315's - i thought that was not enough lite- tried adding an 8bulb, 4ft fluor fixture, but it brought the temps up wayyyy toooo much...
or make your tent explode by using 49*3,5L pots in a 7*7 row lol.
i know they are fitting the tent. these pots are about 15*15 centimeters or 6*6inches
6 litre paddi veg 3 weeks in coco there's so many different reply's which I'm grateful for but just 3 rows or 3 or 3 rows of 4. I be happy with but thanks guys for all the reply's
6 litre that's what I'm using al70. but scroggs a great idea only thing I been thinking of is I wont be able to get at the back of the tent to get to some of the plants to thin them out when I put them into flower. and put a net over them. any ideas guys or would you just let them go. im in dire straights guys so any help I really need it.
If you have the time to water/feed everyday, or the ability to automate your irrigation, running 1-2 liter pots allows the media to dry out quicker and allow you to feed more frequently, thus boosting yields. That being said, if you don't have a ton of time/resources using larger pots and peat moss will allow you to only water 2-3 times a week.
To solve your problem with accessing the back plants, consider building a short rolling table so you can pull it out and work on them. Those less cared for plants will be where your powder mildew or insect pressure starts every time.
If you want or have to grow many plants (for instance you should always germinate a full seed pack or have many cuttings) then :
High Number : 1 imperial foot x 1ft : 1 plant
MaxProductivity vs Effort :1.5ft2 or 1.22x1.22 : 1 plant
SmokeALottaDope : : 3ft2 or 1.7x1.7ft : 1 plant
I recommend to bloom no less than 5 (FIVE) PLANTS from seed within the above plants/ft density. From my experience this will ensure you yield first crop
edit : Regarding pot size @ yes more media for bigger plant - @ 1ftx1ft per plant (3 automated waterings pd) 7.5cmx7.5cm Grodan Block per plant ! @ 1.5x1.5ft/plant 7.5Block onto Hugo; and for 3ftx3ft you might employ more media around under the hugo... Yes, more media will produce more bud so if you have the time and space.... rw is tricky and hope my reasonings work with Coco
