I think your misunderstanding what a perpetual grow is. It has nothing to do with what type of light your are using or what size your table is if you even have one. I have seen perpetual grows that only utilize t5 set ups. To have a perpetual harvest you need only seperate flower, veg, and clone areas, so that when you crop out, you have plant stock to move in the flower room right after and so on. It also does not matter how many plants you have to make it perpetual. You could have one mother that you remove one or more cuttings from each cycle. I hope this helps
what you dont understand is lumens per square foot. u need so many lumens to grow so many plants. for a perpetual setup you NEED to grow MANY plants. PERIOD.
harvesting every 2 weeks, lets do some math: it takes 2-3 weeks of veg + 8 weeks of flowering to produce 1OZ/plant
Day1week1: start 3 clones to guarentee sucess.
Day1week2: start 3 more clones
Day1week3: start 3 more clones
Day2week3: move first clone to flower
Day1week4: start 3 more clones
Day2week4 move second plant to flower.
by this point an individual taking the strongest of 3 clones and killing the weak 2 would have 7 plants, to continue this cycle untill week 11 (8 weeks flower + 3 weeks clone) would mean the individual has 11-12 plants and starts harvesting 1 plant per week.
ok now we get to the real math now that we have an equation.
9 plants flowering x 5,500 Lumens per plant = 49,500 Lumens to properly flower these plants.
4 plants in veg (one mother, 3 clones 4,500 lumens for the mother, and 1,000 per clone) = 8,000 lumens.
now remember his question
could I do it with just one 4x4 table and one 400hps cooltube
can it be done with ONE 400 WATT HPS?? No it can not be done with 1 400 watt HPS. for this reason
actualy it was me who said it was impossible, and thats for a reason. a Hortilux Super 400 watt HPS light produces 55,000 Lumens.
55,000 Lumens (the BEST 400 watt on the market BTW..) is only enough to sustain the flowerin room. he still needs to support the clone room.
this isn;t about tables or BS. i use organic nutes, grown in SOIL, watered by hand for my grow. this is about the lumens produced. and the simple answer is get another light.
