The XL Runtz are performing although one of the two also got stunted and is a little behind on her sister. I've been trying to balance everything. PH, temps, nutes.... With these smaller grow bags, the buffering capabilities of my super soil are less. Furthermore, this grow I didn't add the hydro corn, I didn't add the biochar either. The one 20 liter grow bag seems to perform a lot better while my experience is with auto's that anything over 15 liters should not make a difference. But the difference is: they keep their water better in the heat, they can buffer better and these are aspects that are important in a hot grow tent. The SP 3000 is still performing wonderfully! Very thankful for the opportunity to try it out and recommend this light to all!! So with this lesson learned I'm going to focus on better-growing auto's perpetually, I like how they perform and what they can yield in only half the time. The left one should be getting ready soon. The other and the Forbiddens will take two weeks I think... If they really recover. Thanks for dropping in again!!
