Using water only through the grow?
This is Tad here with KIS. Eyes on Fire makes a great point about these types of soils. If you want to go the entire grow with just water then you have to be sure to give it a large enough container, as we can only fit so many nutrients into so much soil. I typically say a 7 gal container is the minimum size for a full cycle plant on a regular cycle. I haven't done enough work with autos to determine a minimum size. There's a lot of variables though when looking at nutrient uptake such as lighting, temperature, humidity, watering, etc....which can influence how quickly the plant grows and how long the nutrients "last."
@Mr green I would like to point out however,that in my runs of several soils as a water only system @KIS and @Biotabs F69 have gotten the closest to a full harvest with a water only line IMO. But with a few fairly minor tweeks all is right with the world and you have a greener more lush flower/Plant(s) throughout the mid flower cycle lending to far more badassery in the flower department lol so get some Tea recipes and/or a decent bloom boost top dressing prepared when sowing so it has a little time(or before you sow beans ideally by a cpl weeks) to start breaking down.Watering with a dose of Mammoth does help it along over a few weeks.Happy harvesting
Thank you Tad,Means a lot. Many fail to see that Nitrogen for the longer 2 month game needs to be upped with flower foods. I usually see 5 gallon really do well if its deep and well packed do the best all around with medium large and small strains(small is overkill in 5 ,sooo) but little extra feeding tends to be required or less is needed,Have a good'un.
well one I use if I dont have many products to make a custom super batch like Im doing now actually.But Id take a few gallons of soil.and add like 1/2 cup bonemeal,kelp meal 1 cup.bloom and veg granules and water it in with mammoth to start the process and lend a little speed to it all.should do fine if you let it breakdown for a cpl weeks or more ideally.But if I were you I would buy a bloom top dressing from tea labs or build a soil.both have some good products.Havent use BAS top dressing. But tea labs if on point man. 45 wuit shipping for 1CF and well worth it
